It is a powerful floody light when used at max power, but we do not have to use max power. It can also be an efficient dim floody light with long battery life.
There has been quite a bit of interest on BLF in deep red flashlights recently. Sofirn C01R sold out fairly quickly.
Many special uses:
night light that does not contain any blue light, which causes suppression of melatonin and prevents you from sleeping
once your eyes adjust to the dark, deep red light allows you to see clearly without destroying your night vision
Acturally compared with ROT66 , E12R has got more heat-sinking surface due to more and much deeper fins. Heat-sink is not a weak point for E12R. Turbo mode is only supposed to be a short-time use, in this case , adding more weight wont help too much for more runtime on turbo, anyway E12R is not designed to be a bulky light. We still keep it in compact range as possible.
An E12R version with LH351C should be still considered. (A bit less output on turbo /maybe a few percent/, but more throwy beam compared to LH351D, which many of us would like).
Fireflies already offers SST-20 2700K JA3 CRI95 for other lights, which is below BBL when driven at high power (AFAIK), but above BBL when driven at low power.
True, the JA3 bin from Fireflies was the best tinted SST-20 2700k I’ve seen. Basically on the BBL at low currents and below BBL at high current. Still not as good as the E21A 9080 I’ve seen.
They do have the SST-20 2700k and its the best batch I’ve seen in terms of tint. You can email them to make a 2700k version if they don’t have that listed as an option. That’s how I got a 2700k E07.
I also love the name Fireflies, and I also wanted to add to what the poster above said about how “Lite” really is just another way to say “weaker” & “cheaper”. But I am so happy to see that you are so willing to listen to our feedback. I really just wanted to write and tell you Thank you so much for being so open.
I LOVE your lights and I can’t wait for more of your work. ROT66 Gen2 Nichia 219B is my all-time favorite light. I’m kinda worried that one of your new lights is gonna knock the ROT66 off my throne, but I guess that’s a good problem to have
Yes, new optics also works with ST20 emitters , But LH351D hi CRI version can get much more lumens , why still choose ST20 2700K of much less brightness?
If the emitting spectrum is examined in both LH351D and SST-20, the reds in the SST-20 are more complete. This is especially important and noticeable, if we go towards warm white. An emitter being 95 CRI instead of 90 CRI means that, the SST-20 is twice as good as the LH351D, if we treat those numbers as subtracting them from 100 - it is half of the errors in color rendering.
This would mean, that if Luminus would make 95 CRI SST-20 in 5000K, I would also not hesitate to choose that over the LH351D, but for now, in 5000K CCT, the LH351D remains the best 3.5mm×3.5mm footprint LED. Nichia 219C is only marginally better, and it is less efficient.
