I'm sorry to hear about another setback!
I'm seriously starting to loose the confidence in this Project. Cool project but ruined in the execution.
Oh yeah, I forgot I backed this project... Either way, I look forward to the surprise of receiving mine one day.
Interesting that the lowest grade product should have the burn-in issues. Presumably the difference in grades is the bins the LEDs come out of. That being the case, the LEDs with the lower output may have low output because a specific quality problem, like contamination, not just process variability. That could be a real problem for you.
The fact it shows up after a few days of burn-in is very worrying. Many, many, really many years ago I stopped burning in an electronic product I was responsible for, as we were getting zero failures in burn-in. You can't burn in quality. 15% failure is a huge red flag for you guys. Accepting 2% isn't very comforting either.
Good luck with tackling it, and full marks for being upfront about it.
By the way, thank you for the light! It happened to arrive in fine condition and it works well.
Indeed, the top-cap looks like a good addition to make!
wow i do not know if i should still wait for the bulp to appear or not
are there any backers outside the US on the list of the receivers?
@FabianKasper - Oh please, you're actually loosing confidence? Your need to HAVE IT NOW is such a first world problem. Let the creators go though the creative process & worry about more important things. Look forward to receiving a Nanoleaf when it's ready. : )
Yep it would really help if there was some way to see how far up the lists people are to receiving their lightbulb. Personally i should have received in May, and still nothing. I appreciate that you are relatively open though (which i also expect from a crowdfunded product :)
Here's a dumb question, I don't know what Lumen for the bulb I pledged. I chose a 12W (100w eq.)
If you want to keep schedule, you could upgrade the 1,2k lumen receivers to 1,6k lumen. I don't know if there is a huge gap in production costs between those bulbs, but that would give you time to look after the productions problems without getting the heat from your backers for not delivering. Just a suggestion.
Loosing confidence is a good thing... loose it all over the place! :) Losing it, on the other hand... that would be sad.
take your time, as long as it works i'm gonna be happy
This is the first I've heard about the problem. I even went to your web site and complained that I hadn't received my bulb and of course didn't get any response. I was considering complaining to Kickstarter. You should have sent this email months ago.
I got mine a while ago, it works great, and is amazingly bright! So, for those still waiting, it's worth waiting for!
LOL, blame china for their holiday that you knew about a long time ago.
I love to hear funny lying excuses.
You guys already screwed on the color temperature of your light bulbs when you switched from 4000k to 3500K when we all paid for 4000K.
The higher the color temperature the better the light, going lower was a huge mistake.
I'm not worried about the delay. Product development is not automatic, take your time, get it right.
I am worried about a 2% failure rate. With ~6000 backers, that's over 100 people that will see an early failure. What is your replacement policy?
@Laird, thanks for the info!
I agree, just take your time.
I've already gone ahead and bought other light bulbs, I don't know what I'd do with yours if I get it
Plse upgrade if you cannot deliver as you need the goodwill right now! Long Winter nights are coming and cant wait.

WINTER IS COMING!
(sorry, couldn't help it after reading G A Bedard's comment.)
I appreciate the time and effort to make sure the bulbs we get actually work rather than failing in the field. As for the complainers... Kickstarter isn't a store. You're helping to create something that didn't exist before. Delays are inevitable on any complex project. If you can't afford, either financially or emotionally, for a project to be late or never ship, I would suggest to visit Amazon.com next time.
I got my bulb a couple of months ago and it works great. It is the best LED bulb i've bought. But, with prices falling for other LED bulbs I don't think I'd pay $30 for any more of these bulbs. Maybe $15. I have no regrets about being involved in this kickstarter.
I got my bulb several months ago and it has been fantastic. I was unaware of any color temp change until it was pointed out by some unsatisfied contributors, however I have absolutely NO complaints about it. The bulb I received is a bright white, and it rivals the summer sun through my bathroom window.
I agree with Mr. Kling - this is a start-up, not a store. I treat my bulb as a gift in exchange for my support, not a purchase. In that spirit however, I also agree with Mr. Kling that I probably would not pay $30 each for more of them. That said, I have yet to do a comparison to determine if your bulb out-performs mass marketed bulbs at lower price points. Hopefully as production ramps up, the price will fall.
Wishing you all the best for success in this venture!
What I was really hoping for was updated shipping dates per original shipping group. I was slated to get mine in September, is that January now? I don't care when it is, I would just like some idea. If they are only making 100 bulbs a week like the update says that will be more than a year before everybody has theirs. I understand delays happen but the lack of communication from this crew is frustrating.
Awesome.. I just wish I had some way to know when I will be receiving mine. BTW, I work with lasers which aren't so very different from LEDs. It is certainly true for lasers that the lower the power the more likely you are to see an issue, since they sell all the minor defects at low powers.
My suggestion (and I'm sure you've already thought of this) is to do the burn in test in a test bed for each individual LED separately. This will reduce waste by allowing you to only discard the faulty LEDs instead of the whole bulb.
Thank you for the update. Keep pushing through!
Thanks for this update. Hardware is very difficult any I'm sure you guys are learning a ton. For me, this is the entire point of backing your project. I certainly hope to receive a light at some point but my greater hope is that you're able to rapidly improve, expand, and evolve your product. One final comment; recently there was an article published on extremetech (http://www.extremetech.com/electronics/164340-nanolight-led-bulb-strives-for-efficiency-at-any-cost-repeats-mistakes-of-the-cfl) - I disagree with the author's conclusions but it would be great to hear the NanoLight's rebuttal to the color rendering index (CRI) criticism in the article.
@Teal Rogers, I think the issue is not concerning with LED quality, but it's a driver case. So, testing the every single LED not whole assembled bulb is no solution. Guys?
@ Scott Stephens - Interesting article. It fills me with preemptive regret for being so naive about this project. Hopefully the actual product isn't as bad as the author and commentators make it out to be. I've gone from thinking I backed an evolution in LED lighting to thinking that I may have backed the "pet rock" of LED lighting.
@ Scott Stephens - The article uses 2 very poorly shot and cropped up photos with no control method on a smartphone camera to dissuade readers and backers. Somehow, I don't remember "green undertone" as the give-away clue to either poor CRI or warmer temperatures. Warmer colour temperatures should... well look warmer, not sickly. CRI can only be really demonstrated in a controlled environment and with a colour pallet as reference. In this picture, we have no idea what the colour of any other object in the picture actually is, and so there's no telling how well either lights render the colour. The author may not have "editted" the picture post production, but it definitely feels like he tinkered with the white balance in between the two shots to exaggerate his point.
A CRI of 70 and warmth of 3500K is definitely not amazing, it's comparable to modern day fluorescent. Still, 2 photos alone should not be proof enough that the nanoLeaf is subpar in performance.
@Steven - I agree with your comments. The author didn't really do anything but complain and cite CRI numbers as being an all-encompassing measure of quality. It seems to me that the design of the nanoleaf will allow tweaking of CRI in the future as there are 3 separate LEDs on each of the 10 faces. Using slightly different LEDs or coatings will allow the spectral distribution to be tailored.
The three white bulbs in my living room reading lamp have been working just fine for a couple of months now. I like it that I don't need to turn them on ahead of time to warm up as I did with CFLs.
I've got 5 Cree 60w LED bulbs at home, once I get my NanoLight I'll get some properly white balanced pictures of both with some good colorful reference objects to see how they really look in more controlled circumstances.
Thanks for your continued hard work, team! Hopefully, the packaging will make a big difference. (My 2nd bulb arrived safely, so glad your team is on top of it.)
@Seana - You've already gotten two? I haven't even heard anything about my one...
Same here. I'm still waiting for the 1st delivery, even I submitted my address a few months ago already. What's the problem?
I still waiting should been delivery in may. ???
Exclusive WHITE 12W NanoLight that produces >1800 Lumens output
Estimated delivery: Sep 2013
I hear nanolight, I don't see nanolight. It would be nice if they send us an update, even if it is going to take a bit longer to get them. Better to know than staying in the dark, right? Illuminate us...
Just send me a notification when you ready to ship.
So...if I plan to move before the end of the year, should I be worried?
Want more updates. Don't leave us w/out bulbs((
where is my lightbulb ????
Thanks for the e-mail updates. Really appreciate knowing how things are going. I support your team and all of the hard work that goes into a start-up. I'm also looking forward to ordering more lights once they are in full production and if they are everything that I'm hoping they'll be.
It's December and have not received 12W nanolight delivery for September.
Now mid December & no delivery or news since October? Is this a scam?
