We've surpassed our goal! Now a look at what's to come.

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

Hi Everyone! 

We are a quarter of the way through our KickStarter campaign and the reception has been incredible! We have well surpassed 80k and there are supporters from all around the world. Thank you to all the backers out there for the incredible and generous support that you have given us so far. 

On the manufacturing front, we have been working very hard to find all of the suppliers and components needed to support our first batch of orders that are scheduled to ship out in May. Our plan is to line up all the orders so that once we get the needed funding we can pull the trigger as quick as possible. So far, we are right on schedule. 

We have been listening! The NanoLight is the first large scale project that has come from our drawing board and as such, we value your feedback immensely. We have received quite a lot of interesting feedback since the launch. Here are some of the top items that came up:

1. Can you make the NanoLight Dimmable?

This is now a work in progress. One of the great things about a dimmable bulb is that when you run a bulb at a dimmed level, it actually takes up even LESS electricity! We are working on a prototype and should have an update for you later on. As with our other NanoLights, our goal is to be able to offer the dimmable NanoLight at a competitive price point and without sacrificing efficiency.

2. Can you use the NanoLight in a fully enclosed fixture?

Most LED light bulbs or CFL’s have a problem of overheating within a fully enclosed fixture, which causes the LEDs to start failing well before their expected lifetime. The reason for this is that these fixtures do not allow for sufficient air flow, thus trapping the heat inside and overheating the bulbs. We cannot claim that the NanoLight will work in absolutely all enclosures, but we can say that the NanoLight emits less than half the heat energy as compared to other LED bubs or CFLs. The chance of overheating is far lessened. After receiving various question regarding fixtures, we realized that these bulbs are going to end up in all kinds of installations. Of course, we want to make sure that the customer gets a long life out of these bulbs so that they pay for themselves over the long run. As a result, we are happy to announce that we have added overheat protection as a standard feature of every bulb. If the bulb gets too hot for whatever reason, it will automatically dim itself to prevent damage or shortened life.

3. What happens to the NanoLight during a blackout or a brownout?

The first part is easy to answer. During a blackout, the NanoLight will shut off. It’s the most energy efficient light bulb. We never said anything about it being able to run when there is no power. We recommend you have a flashlight on hand during a blackout. During brownouts, the story is more interesting. In some parts of the world, brownouts are deliberately invoked by the power company when power demand cannot be met. Many items connected to the power grid draw less power when the voltage is lowered. Thus, a brownout is a measure taken so that a blackout can be avoided. We have a variable AC power source that allows us to simulate different world voltages and brownout events. Some of the feedback has prompted us to do a more thorough study and even adjust some component values in order to extend the operating voltage range as much as possible. We are happy to report that the NanoLight will continue functioning normally with the same light output level during most brownout situations. If the brownout is very extreme to the point that the NanoLight cannot get enough power to function normally, it will dim. Through the various tests, the NanoLight has not failed due to undervoltage.

4. What's with the funky look of the NanoLight?

For many people, it's hard to get used to the look of the NanoLight. We knew right from the start that the look is highly unconventional and we had a lot of uncertainty about how it will be accepted. We were hoping that people would realize that most bulbs are hidden away in enclosures and never seen, and for those people, the look should not be important. In certain installations though, we think the NanoLight is quite fitting, offering a unique futuristic look. We can’t wait to see what people do with these bulbs!

STRETCH GOAL

That said, we have not stopped thinking outside of the box, and at the same time, are trying to have a little fun with the look of the bulb. We are considering the idea of imprinting artwork onto the shell of the NanoLight. We are working with a graphic designer to come up with some ideas. We will release some concepts once we hit a funding level of $120k and depending on feedback, we may offer all NanoLights with an imprinted design. This may just be the most energy efficient light bulb and also the most artistic!

Thank you all again for your support! We're excited to get started in making your NanoLights!

      Disappointed that you moved the color temp warmer. With all this success you'd think that instead of offering cosmetic 'designs' on the bulbs you could offer different color temp choices. Please reconsider!

      Art is pretty although prefer plain as a cost measure so perhaps keep art to packaging instead. Futuristic look you've achieved the way to go. Um, I'm not very scientific and don't pretend to understand LED or its technology, but can it come in full-spectrum light? Enlighten me (pun intended). Will pledge more as budget affords. You make Canada proud.

      Doesn't do anything for me. Don't bother adding the print.

      The reason this lightbulb is innovative is that it functions as a black body. Think about the shape of the interior and the placement of the holes... The biggest problem with an LED-based bulb is dumping heat and to that end you see designs with big, massive heat sinks. The OTHER way to radiate heat is as a blackbody, and I'll bet dollars to donuts that their first design was black on the outside.

      I'd further bet that if you looked at an UNPOWERED bulb of theirs with an IR camera, you'd see the little holes as hotspots.

      If this actually works, it will be really cute. A combination of a blackbody radiator with low mass and low cost, and a simple, build-able design.

      My biggest concern would be how it performs in an environment with constantly changing temperatures -- this is one of the two major reasons why most LED stoplights fail: #1 electrical joints failing from temperature changes and #2 vibration from traffic. I hope they've over-designed that part.

      In 2009 I initiated the exchange of all the bulbs in my house by lighting the LED. Last year I finished; today my house is 100% LED! Or almost, missing have lighting to LED refrigerator, microwave and stove. I get really excited when I know something new in the area, so do not wait to get in my hands the NanoLight to do various tests, and then buy more and more. Congratulations on your initiative.

      I like the look, I'd prefer dimmable, but that's not a deal-breaker for me. Maybe a future product... And yeah, 4000K is a tad on the bluish side, but acceptable. One target use for me is in my basement, so I'm in it more for the lumens.

      One comment/question about heat & reliability: one of the main points of failure in compact fluorescent bulbs & such is electrolytic capacitors. Cheap bulbs typically use 85C rated parts, instead of 105C or higher. It sounds like the nano-bulb should be fairly cool in operation, but it is an enclosed space with little ventilation. Do you use electrolytics, and if so, have you life-tested them at temperature?

      I'm in Australia and I'd like our Voltage which I understand to be higher than the US (240V) not to compromise the lifetime of the globe. Please,

      Congrats! All those suggestions for added features are interesting but would definitely increase development, design, manufacturing & logistics costs so best to KISS (keep it short/sweet & simple). Dimmable option is good enough.
      Another thing is once you go into China to try & reduce costs be prepared for intellectual property issues, etc. Don't be surprised if you see clones of your design being sold already! Good luck! :)

      Adding my voice in support of the current design and look of the bulb. It's what first drew me to your project and I'd be extremely disappointed if it got changed. It has such cool factor (in both white & black!)

      Also wanted to say that I'd be more interested in a true-white bulb over a dimmable one. But overall just not any of those blue-ish LEDs in bulbs you can find today -- those are horrible!

      RE: Dimming
      I assume you have looked at shutting off one or two of the three LEDs on many of the faces of the 'bulb' rather than dimming all of the LEDs. Can you share any thoughts on this tradeoff?

      @ Corporate3-6

      found some more information here: http://phys.org/news/2013-01-kickstarter-team-bulb-world-efficient.html

      "214V and 0.1A gives about 21V*A apparent power. The power factor of 0.57 means that about 21VA enters the bulb, 12 are used to power the LEDs but the rest will return each period in the grid as reactive power (and I see a big capacitor in the bulb, which makes me believe that the reactive power is capacitive - the worst that could be). Energy distributors doesn't like reactive power and for good reasons.The very small power factor of this lamp denotes the cheaper schematic used to power-up the LEDs, the classical chinese way of doing things. And they show you only the active power, when the total power used by the bulb is roughly double."

      I don't know if that makes sense but you being an electronics designer can probably tell us what to think of that.
      Thank you.

      For what it's worth, I love the current look of the bulb!

      The assembly time-lapse at the end of the pitch video made me wonder if you might also offer a "fold it yourself" version. I'm assuming the things aren't horribly delicate, and it looks like it doesn't even need any/much soldering, so I would go for that option in a heartbeat. (Who assembles their own lightbulbs?!) From a business perspective (assuming it doesn't involve some liability junk), it might save a little time/cash on the labor (not to mention the calluses) for this initial run...and perhaps on packaging/shipping, though I have no reference for that aspect.

      Wish to see some compare charts or list.

      Really wish the color temp was adjustable.

      Do not abandon the 'funky' shape, that shape gives better light coverage than any on the market - many folks will use it horizontally, others in a shell reflector - your design works.

    16. pclabtech on

      Quick question (it was the first immediate one that popped in my head reading this update):

      How failsafe is the "overheat dimmer circuit?"

      I fix computers that won't boot due to overheating alarms in laptops that is only caused by a wad of dust crammed in the air vents. Remove the dust and the unit stops complaining. Is it possible that the sensor could give false positives and forever dim your bulb? Any way of bypassing this circuit if it fails?

      The obvious artwork - the sun's surface.

      Guys, can you please tell us more about how you are so far in advance of all the other LED technologies out there? Everything else needs a heat sink... you say you don't because your LED's emit half the heat energy, and are also about twice as efficient in lumens per watt as every other LED bulb on the market.

      I am an electronics designer. I am very much interested in helping out fellow electronics guys and businesses, plus I think the light looks cool as hell and want to support you - but I don't want to be throwing money away either. I would really like more detail because so far it sounds like magic beans.
