One Week to Go!

Posted by Gimmy Chu, Tom Rodinger, Christian Yan (Creator)

Hi All,

We can't believe we only have one week left to go! It has been an incredible ride and has far exceeded our expectations. We're well beyond 1000% of our initial goal with still some days to go. We are learning and growing so much from this experience. Needless to say, we have realized that there is a great demand for this type of product in the world. People are thinking green and we absolutely love to see it! The money that we have raised on Kickstarter is going to be used for even better things. Please keep watching us because we are dreaming big. However, first and foremost, our top priority is to deliver the first batch of NanoLights to the backers on time.

Update on Manufacturing Progress:

We are progressing very well with the manufacturing setup and are happy to still report that we anticipate on time shipments. For the past few weeks, we have been diligently overseeing the LED packaging process and performing extensive tests on the sample order of LEDs that we have received. The LED that we're using in our bulbs is the most critical part of the NanoLight, so we are taking extra care in ensuring a high quality product. Our standards are very high. As well, we are working with the assembly factory in defining every aspect and detail of the manufacturing process. This factory is run by a German guy and we expect nothing less than German perfection. The bill of materials, which includes sources of all parts, is getting close to final. We have conducted our first meeting with the staff of the assembly line to start to train them on the assembly steps. The testing and quality assurance procedure is very much defined now. Each NanoLight will go through a few stages of testing which ensure that the power consumption and light output are within tolerances among other things. About 5 hours of testing and burn-in will be performed for each NanoLight. Although in some ways it is sad to see the Kickstarter campaign coming to an end, at the same time we are truly excited to be entering the next phase. The funding will be released to us sometime in the second half of March. At that time we will pull the trigger on the large scale manufacturing. In the mean time, we will continue optimizing the process and making samples on a small scale to ensure an efficient manufacturing setup.

Dimmable Feature Update: 

The dimmable version of the NanoLight is currently still a work in progress. We have worked out several of the technical details and have a prototype that is already functional and dimmable. We are now a lot more confident that a dimmable version of the light bulb will see the light of day in the near future. That said, we are holding off on the official announcement because we once again want to bring exciting innovative features to the world. Like we are reinventing the light bulb, we also want to reinvent the dimmable light bulb. Since our Kickstarter project is drawing to an end in a week, we are not going to launch this new dimmable light bulb during this campaign. We feel that the dimmable light bulb deserves it's own launch. Please wait for it… we promise you will not be disappointed.

Mysterious LEDs

We have received a lot of questions about what kind of LEDs we are using. So far we have not revealed very much at all. To say a bit more, the LEDs are in many ways our own design and are not something you can buy off the shelf. Many of the parameters that define the LED are under our full control. We are working with a few vendors that supply parts to make the LEDs and ultimately the LED is assembled into a working light source. Of all things, the greatest effort has been expended in designing the LEDs. We haven't stopped. We have gone through several iterations of making samples and testing using a range of parameters. We have evaluated several tradeoffs that are inherent in LED design and we are very proud of what we will be able to deliver to you.

Color Temperature is now Warmer!

Originally we announced that the NanoLight will produce a "bright neutral white with a bit of warmth". More specifically, we chose a 4000k color temperature that puts the white color at about what you get outdoors in the evening sun. This is a very pleasant white colour that is versatile in your home. However, we admit that a 4000k color temperature is not ideal in the bedroom. In the bedroom, people have become accustomed to even warmer light for extra comfort. What we want least is for our backers to receive their NanoLights, install them in their bedroom and then realize that the light color is not quite what they expected. For this reason, we have decided to lower the color temperature to 3500k. The light output will be more appropriate for the bedroom and will still be perfectly usable throughout the home. We want as many of our backers as possible to love their new NanoLights. From a technical point of view, we have managed to do this without sacrificing efficiency and there will be no extra cost to our backers. For the Kickstarter project, we need to limit the complexity of production to only one color temperature but in the future we will offer more color temperature choices.

A New Reward - The World's Most Efficient Light Bulb!

When we announced the NanoLight to the world on Kickstarter, we called it the world's most energy efficient light bulb. As far as we knew, this light bulb was more efficient than anything we have seen anywhere on the market, by a good margin too. However, we thought for sure someone would at least attempt to challenge that claim and point out something that is more efficient, something in existence that we have overlooked. Well, it has been almost 2 months and the NanoLight has made news stories around the globe, but no one has challenged it's efficiency yet. It looks like the NanoLight really is the most energy efficient light bulb out there. But… speaking very literally, there can only be one single light bulb that can be crowned for being the world's most energy efficient. And… we will offer that light bulb now as an extra reward. In this last week in our Kickstarter campaign one person can take that bulb. We guarantee that from all the light bulbs we produce, this bulb will be the best single NanoLight. It will come with a testing report and a certificate of thanks that will describe some of the things that the generous contribution will allow us to do. The backer can also request a particular design or imprinting of text onto the shell of the light.

Photo Contest

Let's have some fun! …and at the same time help with an important purpose. We want to get as many NanoLights out there as possible so that the world can start saving electricity and lowering greenhouse emissions. For this reason, we would love to see as many uses for the NanoLight as possible. At this stage of the game, we badly want to learn how our product is being used so that we can inspire more people to use it that way or it may point the way to future product innovations. Once you receive your NanoLight, please please take a photo of it in action. We want to see your photos. The world wants to see your photos. We are going to hold a contest (details to be announced) and in return we will be sending out a bunch of free NanoLights to some of the best entries. As entries, we will also accept hand or computer drawn artwork that depicts the NanoLight. Help us come up with some great uses for the NanoLight. We will learn from each other to make the world more green.

One week to go! please continue to share our project with your friends and family.

Best Regards,

The NanoLight Team

      I know that I get in here too late at the game because I only just found out but I'm one backer that is extremely dissapointed about this bait-and-switch act played here.

      I backed to get 4000K bulbs, just like other led strips and down lights etc I already have installed - they are not easy to find because all the cheapos are 3500K or less and hence I was thrilled to find a good design, enough power and correct color temp in one product.

      @Steve Mercer: Changing the color temp requires changing the led that is used in the bulb, the color comes from the coating on the led itself. However that change is not a major one - all the other properties are the same so this change can be done at the production line by just putting a different roll of leds to the machine.

    2. Peter Wysoczanski - Obsidan Order on

      I'd bet money that it has to do with money on why to go with 3500k.. my Judge II uses 6500 to match color... I too would like to get the 5000K to get a better color spectro

    3. Mark Knapp on

      If you read most of the comments you'll quickly realize the 3500k bait n switch is jive ass! Why all the questions about other design features and then pull this?!

      @Edwin - WHO was complaining about how harsh 4000k lighting is? It certainly wasn't me.

      I have changed all of my home lighting to daylight CFL's (Which are 5000+ kelvin). Whilst 4000K would take some getting used to, 3500 is back to being too warm. For people who say that you can't even tell the difference, believe me, you can.

      It seems to me that this is an easy thing to change - probably just changing a resistor. It can't be a major change as that is not something anyone would do this late in the game. How about making it adjustable. A variable resistor should do it.

      As to the bait & switch tactic. I feel you need to deliver exactly what was promised. If you want to change ANYTHING do it for the next batch. Your pledges came in based on specific details. I know I want what I paid for along with many other people.

      The color switch is not a big deal to me. I doubt anyone can tell a difference. They did not change the color to be cheap, they changed it because people were complaining about how harsh 4000k lighting is. Now they make it warmer and people are still upset.

    8. Richard Perry on

      I am another person that wants a 4000K bulb! GIVE US THE CHOICE!

      How can you ask about a leaf pattern, but not for something major as the color?
      I use 5000K+ daylight CFLs around my home, I much prefere them to warm.
      If people want a warmer color, all it takes is a cheap colored lampshade.

      Very disappointed, the cool color was my main reason for backing this :(

      Happy to hear you guys are constantly trying to improve the product. Don't worry about the 3500k haters - most don't know what they are talking about. Can't wait for delivery but remember that nothing trumps QA/QC. Design for reliability and manufacturability and get it right the first time!

      Thanks for your comment, Renee.

      These guys have done some awesome research, and we can trust them
      with the colour temperature too.

      Sometimes you've just got to trust the people who have the actual product, and
      have done the product testing.

      Continuing success to them!!!!

      Renee Green on

      Hi all. Just wanted to support the change to 3500k. I have quite a bit of experience with lightbulbs, especially currently available LED lightbulbs for home use, and the 4000k and higher color temps really are undesirable for home use. It's not a matter of brightness, but that those bright white colors are hard on your eyes -similar effect to walking into Wal-Mart at night and being blinded by their fluorescent lights -VERY undesirable for households. Whether most of you realize it or not, you've likely lived most of your life with household lightbulbs in 3500k and lower color light. That's the color range closest to most incandescents (you know, those 'traditional/cheap' lightbulbs we've all used for the past hundred years). The change here from 4000k to 3500k is a GOOD change and does NOT affect the brightness (like some people think). For those who are skeptics please do some thorough web research on this, or at least wait till you receive your nano light to see for yourself. Thank you.

      I am not over joyed with the change to 3500k. I had intended to use this "bulb" in the kitchen, where I like a bright white light. Nanolight was backed for specific task lighting. Use of this "bulb" in the bedroom never crossed my mind. How about offering backers a choice?

      Complaining before you've seen the final product seems strange to me...
      Don't fight about numbers!
      We are supporting them to get the product to market. It's still in developing... In my opinion changes are normal for this production stage. All backer should know that...

      By the way: I prefer a warm light for my home :)

    16. pclabtech on

      @Ryan It's moot at this point, even after the update, their numbers continue to rise not fall. If I were an actual investor (Oh wait, we ARE) we would have a say into changes that will be made to the initial design. They mentioned they asked backers (but didn't use the word 'backers') their preference. I don't recall any poll, questions, or requests from us on temperature of the bulb.

      I did like the demonstration on Discovery channel, please Lord tell me that was the 4000K bulb.

      BigByWolfe said it distinctly, You don't show, demonstrate, and promise backers something, and then, knowing that there is no chance of failure, change the product at the last week of the funding, with all of the NanoFanbois jumping at us who are trying to understand the reasoning behind such a bad business decision.

      I was supporting you for a bright, non-yellow, 100W equivalent bulb like the one on Discover Channel. That is what I expected to get.

    17. Missing avatar

      Ryan ONeill on

      You have to switch back to 4000K that is what you PROMISED us.
      3500K is more yellowish light that makes colors look wierd.
      Most people buy 4000K+ lights, cheaper lights are what is less than 4000K.
      Go to any home depot, they have a light setup showing the range of colors, over 5000K is what makes you see correct colors in your house and provides you the correct light for any activity.
      4000K was alright, but 3500k is a bait and switch.
      You are violating everyone's trust by cheapening up your lights. It is obviously this change gives you some kind of savings in your LEDs. What have done is just wrong.

    18. Chris Garcia on

      Hey, nanolight guys. Sorry you're getting flak about the color temp.

      I'm thrilled to see what you've worked so hard on; but I'm a backer because I think your idea is cool - not because I need a lightbulb. Keep making the best bulb you can. I'll trust you to provide a nice color temperature. You guys have tried living with the prototypes for an extended period and genuinely prefer the warmer white, right?

      Good luck scaling and shipping with 10x the demand you anticipated!

      Hey Yan/Chu/Rod:

      I sketched up some pictures :)

    20. Bigbywolfe on

      I sent this to they guys directly, but figured I would share my feeling here as well:

      "I'll preface my response with the fact that I am not a scientist, electrician, lighting specialist, business specialist, or whatnot. That being said, let me express, in layman's terms, what this feels like from my perspective.

      I prefer the brightest, cleanest, "whitest" light I can get, which is why I chose the 100W-Equivalent instead of the 75W-E. When I pledged to this Kickstarter it was not to fund a prototype that was in it's infancy with you giving a rough guess at what the final product would be like. You already had the prototype. You had the research. You had a finished product and you said "this is what you will get". Now, with only a week left and no chance of failing even if people pull out because you are so far over your goal, you say "we figure this will sell better in the future so we aren't going to give you what we originally promised". That is unacceptable. You didn't even ask those funding you for an opinion first. It shows not only a tremendous lack of foresight, but a lack of integrity.

      I was excited to support you guys and be in at "the ground floor" of what I hoped would be a revolution in energy saving. Now I'm not even sure if I want to do business with you."

    21. Gimmy Chu, Tom Rodinger, Christian Yan 2-time creator on

      Hi All, i think there has been a bit of a misunderstanding. 3500K is definitely not a significant difference from 4000K. Majority of lightbulbs that are sold in stores for the home that are labeled "Warm White" are 2700K. Cool white would be around the range of 4000K - 5000K. Considering the brightness of our bulbs, even 4000K seemed a little too white for our liking. We felt that adjusting the color temperature to 3500K created a better feel for the home. This is not limited to a bedroom, but for the living room, family room, dining room, etc. The difference is very slight, and to most people will find the difference barely noticeable.

      We apologize for making the change so late in the project, but we felt that once people get their hands on the bulbs, they will like this color temperature better.

    22. George Pabis on

      Are you really going to test every light bulb for 5 hours? Is that really necessary? It seems like a waste of energy. If you can show that your manufacturing process is in control, then you should only have to do testing of samples and not 100% testing. Please feel free to contact me if you need help with statistical process control.

      Isaac Luria on

      Another vote against warmer color temperatures. If I wanted a night light in my bedroom I wouldn't be using an 1800 lumen bulb. Neutral color temps are better for people who are awake. Sleeping people don't need any lights.

    24. Jessie Shoshone 3EV Paintball on

      I'm very excited about this project. Also, I'm a light bulb fanatic. I have a house full of CFL's that emit light from 3500k to 6500k and at a minimum of 60W. With that said, I am not too big a fan of CFL technology and would love to see and extremely efficient and cost effective LED bulb hit the market. I love very bright light, and I find a use for various wavelengths in different settings and in different rooms. I typically prefer a little higher wavelength for an all around type bulb though, and I hope to see you offer that in the future. Not much will prevent me from backing this(and I've considered raising my pledge), but I'm not a fan of going to a warmer color.
      With that said, I hope to see your light "bulb" design become the way of the future for the world.


    25. Joshua Garber on

      Please consider moving production to US after a few production runs. The us production quality and efficiency is usually far higher than most other country factories. Though I think you lucked out with a German manager in South Korea.

      are you kidding me? who's using a 100W lamp in his bedroom?
      i wanna have white light, not yellow one! thats why i decided to place my order!
      if you wanna offer different colors, than do this, but don't change the specifications of my ordered bulb.

      i hope you think about and change your mind. otherwise i will have to replace my order.

    27. Jonathan Hodgins on

      I've never been a fan of the warmer coloured lights, I much rather have it towards neutral. My pledge will sat the same either way, but I would prefer the neutral colours.

    28. Michael Anderson on

      I personally do not want a 3500K bulb. I specifically purchased this bulb because of the 4000K & actually would prefer a bulb of 5500K. I settled for the 4000K because that was what was offered & that is OK. I for one would like to back out of this purchase & get my money back if you can't deliver the product as presented.

      I hope then you consider other applications
      for ex. art studio lights

    31. Kevin Lampo on

      I do not understand why a warmer temp is being considered. Who has a 100W bulb on their night stand? Most 100W applications are in living/kitchen areas. 4000k is the perfect color temp for the wattage output. If you want to go 3500k make a 60W replacement for the bedroom.

    32. stephane.p ~ BigEyes Games on

      I'm happy that you have lowered the color temperature!

    33. Thomas Shearer on

      Bad news about the color temperature change. If I wanted a sickly yellow bulb, there are many already on the market. 4000K is my minimum for lighting color, so you just lost my support. Save one of the 4000K bulbs for my reward; you can keep the 3500K.

    34. pclabtech on

      Oh yea, I forgot when I posted earlier... please keep the 4000K temp for the bulb, I too am using it for other purposes than general room lighting and do not want a warmer bulb.

      I forgot to mention how long I've used Jonathan Ott's full-spectrum eyeglasses and lamps.

      Direct halogen light has been implicated in cancer--the retinal nerves directly affect pituitary function.

      Would I mind reading in full daylight? 5000k? Well, what's the CRI?

      Just because a bulb saves energy doesn't mean we need to force the public to get used to uncomfortable light.

      If you stick with incandescent colours at standard wattage, everyone will be happy.

      The change to a color temperature of 3500k is a bit disappointing. Since I would use a 12W NanoLight in either my living room or my workroom but not in my bedroom, the 4000k in the original promise was one reason to back this project.

      Carl Hinke on

      I'm really excited about NanoLight and, as an old, retired guy I don't have much money to kickstart. In my part of the world, Asia, it is highly unlikely incandescent bulbs will become dinosaurs for decades. And, personally, I don't find the energy consumption of incandescents troubling.

      I'm a big reader and I'm far more concerned about the comfort factor of the light's quality. Thus, it disturbs me to read here that NanoLight will be 4000k when Wikipedia tells me incandescents are 2700 to 3300k and 4100-4150k are 'moonlight'!

      Well, kids, I've never read by...moonlight! What you needs to hit is a comfort zone determined by wattage equivalents: 75-100W incandescents are best for reading.

      Every 'energy saving' lightbulb I've seen so far generates horrible light. Don't make the same mistake.

      I just insist that the color temperature of the lamp was 4000K! And not a drop of less! I have a feeling that YOU think not about what is best for the buyer, and about what is best for you! IF YOU ARE NOT CHANGE I'll take my money!

      Pretty disappointed to see dimmable won't be in this batch of bulbs, not even at the 100 dollar level. Also I would have much rather seen an increase in CRI then any change in color temp. With a color temp change you are going to annoy some backers that bought into this campain because of the 4000K temp, in contrast nobody would have complained about a 90 CRI.

      You just lost my $45 pledge. As it was 4000K was a bit warmer than I wanted but now dropping the color temperature down further to 3500K is just not acceptable to me. You could have at least sent out a survey to all of your backers to see what the backers wanted. I wasn't planning on using this in "the bedroom" and who wants to use 100W equivalent bulbs in the bedroom anyway?

      I am delighted that you have moved the color temp warmer. My 35 years in the lighting industry has shown me that this is what the vast majority of customers want. Most people have a very strong preference for warmer light. It may not be the very best task light but it is what people will want to buy and use.
      It also gives my lampshades a more beautiful color.

      Thanks for all your attention to detail,
