Cool :+1:

Actually, quite warm

Fresh snowfall here, bet it would look cool at night on it.

Don’t eat the yellow snow

Thanks for the testing djozz. Are you leaving these leds in the Q8 long term?

Yellow snow, you can have it.

Ewww, didn’t think of that.

Wow. I”m envious, as I have made a lot of amber lights to avoid screwing up my nighttime sleep cycle.

Maybe 3300 lumen of yellow is not ideal for your sleep cycle.

It probably depends on Luminus. I think it makes sense that now that they started with the other cool and neutral 70CRI CCT’s of the SST-40, but not 4000K and warmer, that at some point they finish the SST-40 line-up with warm 95CRI versions. One can hope, right?

Whats up with the Giant Gangster Whitewalls on the chick bike, Is that a happening fad over there for cyclists or a safety thing? The Yellow Bile colored beam really makes them POP!

djozz · 2019-01-20T11:26:22.000Z

It is very common to have a reflective strip on the tire over here, it helps a lot with safety. But this particular bike seems to have reflective rims instead.
Same bike in daytime:

Really looking forward to your test results on the pink one when you get a chance sir.

I almost bought some big pink COB’s last month but didn’t want to deal with the inefficiencies of Chinese COB’s, I didn’t know pink epileds existed.

There you go ^
It would make sense if the behaviour was similar to the yellow one but it seems a quite different led. It did not even die at 10A when I stopped the test.
I made an S2+ shorty with BLF-A6 driver to check the led. It is indeed very pink and puts out 400 lumen on a 18350 battery. With some bypasses and such it should do over 600 lumen.

respect you got the rosiest tine ever achieved in a flashlight

Kawiboy his camarea has no or not good image stablisation

djozz · 2019-01-21T00:06:54.000Z

Yes, just checked, my ROT66 (219B V1 sw45 R9080) at max looks yellow next to this one :party:

About the bike shot, it was my phone camera, I did not hold it still enough for the beamshot.

Not an Epiled, but got some “bead” type pink LEDs offa Amazon. They’re pretty interesting. Got one in a drop-in, which ended up in a pink/purple/whatever ’501 that I got offa FT.

Call it a Barbie-Light…

Hang on a sec…

Here ya go. Go crazy…

Aparently not.

I was bored and started toying with a few colour flashlights. I thought that if I could fill in the spectrum of the pink one with a green (530nm XP-E2) flashlight, it might get close to a usable white. And behold, after some varying light levels I even got 80CRI close to the BBL with a great R9. . And it shows, when sliding the pink and green hotspots until they overlap all of a sudden a clear and pleasant white appears that gives fine colour contrast. It is not that I do not know that it works like this, but it is much fun to see it happening before your eyes.

DavidEF · 2019-01-21T23:08:31.000Z

Nice! Thanks for all the testing djozz!

adam7027 · 2020-10-15T15:51:38.000Z

Sorry for thread necromancy, but I seriously consider this emitter in an OP reflector Convoy C8+.

Could you please tell me, where this led can be purchased, and point me towards manufacturer spec document?
