So I finally received these lights, nice quality and bright. I removed diffuser from one and now its really crazy bright for 1,2W - almost unbelievable for such a small power consumption. Can anyone identify brand of these six LED? Any easy mod to get even more brightness out of them?
ordered one from GearBest for $2.09 w/ free shipping.
Yes!!
And I won it in your LightsCastle Weekly Guessing King Campaign 
Good Luck.
And please me your address,we will dispatch it to your side.
its always in my bag. love this led light.
has anyone tried to leave it on for lets say 8hrs straight?
i wanted to use it as desklamp.
Me too :bigsmile:
I am looking forward to try it when it arrives. I have also ordered a Xiaomi fan for hot summer days. Anyone tried one of those?
Kind regards
Thank you LightsCastle. Just ordered 4 pieces from your website.

Thanks for your order.We will dispatch the items ASAP.
Got mine today. For the price I paid ($2.09), how can you not like it ?. It's fairly bright and built well..
Got one a couple of months ago. Haven’t found a use for it yet, but it is very well made and quite bright too.
I haven't found a use for it yet myself. It was cheap enough. I couldn't pass up the great deal GearBest had. Call me an impulse shopper, I get it....Guilty as charged...
Geekbuying had them for 1.09$, verified originals…also bought (too) many. I use them for:
- gifts
- work light (soldering, car repair stuff,…)
- macro photos (several of them from diferent angles, well difused light)
- behind laptop and lcd monitor (running 24/7) for ambient lightening - these ones have added aluminium foil+thermal paste
Wow, you’re not kidding. Just received my USB lights today. Was not expecting them to arrive this quickly to New York this fast. Arrived very well packaged and all in perfect working order.
Thank you LightCastle. Next flashlight order goes to your company!
I finally got my 10400 Powerbank today (Actually it’s my second one - but this time it’s an original one that I don’t have to throw away…) - with green silicone-sleeve and fitting grteen LED Light.
If they only made that little ventilator also in green…
I like that light - the CRI isn’t great, but it’s bright and looks nice (and it’s cheap).
Hi, i received mine yesterday. Turned it on and after about 2 minutes, there was a burn smell coming from it. Is that normal?
No, mine doesn't smell.
Ran min on a genuine 10400. Don't know how long the total run time was, but it was running for at least 24 hours. I wish there was a moonlight mode or a version that was less bright and could run much longer. Just as a backup or for longer trips.
Its probable that i got a defective item as there is quite a strong smell. I’ll avoid using it as i would not want for my power bank to get damaged. I will contact the seller and hopefully he/she sorts it out.
UPDATE: I received a replacement light and it does not have the burnt smell.
I have also remove the diffuser and the light is very very bright.
If anyone is interested I measured the Tint and the output from two of these handy little lamps (org. Xiaomi, one blue and one red).
They measured very close to each other although I could see a slight difference in tint.
The blue one: xc,yc= (0.414 , 0.422) = 3514K , 82 lm
The red one: xc,yc= (0.414 , 0.419) = 3498K , 78 lm
The color point corresponds to a bit greener than BIN 6B3, one could call it 6S, if this was defined in the BIN chart.
I intent to experiment with adding some red paper or a rosa filter underneath the diffuser to get rid of some of the green, but it is usable as is.
Beware, there are (unknown) tolerances on these measurements although I am more confident with the color measurements than the lumen measurements (Used instruments: Color Analyzer and Integrating Sphere).
