Fireflies NOV-MU 21*Nichia E21A mule 1x21700 Flashlight --in stock

For me, I like duv a little below the BBL. It just feels so much more relaxed and welcoming. I’ve tested many lights with near perfect color rendering but lack the slightly rosy tint I like to see before bedtime.

Ah yes, me too, and apparently most humans , Sunlike SOL are perfect compared to the reference black body.

I have a D4v2 and KR4 16x E21A mule and see absolutely no tint shift. The only issue with those mules is the positioning of the emitter around the outer perimeter causes a whopping 20% output loss and narrows the beam. The positioning of the emitters at the center in the FF mule will resolve this huge issue. Also FF made the right decision to use white mcpcb unlike the KR4 mule with the red MCPCB. White is the most reflective and the color DOES make a difference in measured output.

With 21 emitter and the optimal configuration mentioned above, this should make a good amount more than the specified 5,000 lumens at startup, especially considering this uses 21700 instead of the 18650 in the 16x E21A mules.

If this can charge and be used at the same time, then it would make for the perfect table lamp. The E21A 9080’s light quality is better than any light bulb I’ve tested and I tested ALOT!!

I saw your post about the light loss previously and indeed here this is a much better design, but maybe that’s the reason you didn’t notice the tint shift ? since it’s cutting most the greener light.

For lightbulbs the best I’ve seen are Sunlike SOL basically perfect.

You are right. I took out the bezel and tested it again and there is indeed some tint shift at the very outer edges but fortunately they are outside of our peripheral vision, which is why I guess I never noticed it. However the tint shift is nothing as bad as Cree or Samsung LH351D emitters. You can always put a piece of DC-Fix or sand down the glass to diffuse the light.

Anyways, this is looking to be the best portable photography light on the market by far. I’ve been using the X80GTvn and KR4 E21A mule as my photography light but this looks to be miles better.

I might have exaggerated a bit with the “terrible”

Here is a quick measurement :

E21A 5700K (50mA) :

0° 2784.7 Lux, CCT = 6398K (Duv –0.0026)
12.5° 2663.9 Lux, CCT = 6300K (Duv –0.0021)
25° 2016.4 Lux, CCT = 6105K (Duv –0.0010)
37.5° 1819.2 Lux, CCT = 5850K (Duv 0.0006)
45° 1593.0 Lux, CCT = 5710K (Duv 0.0016)
57.5° 1188.4 Lux, CCT = 5424K (Duv 0.0038)
70° 863.2 Lux, CCT = 5142K (Duv 0.0060)
80° 587.3 Lux, CCT = 5032K (Duv 0.0070)

XHP50.2 for what is probably among the worst out there :

0° CCT = 8061K (Duv –0.0065)
25° CCT = 7191K (Duv –0.0031)
45° CCT = 5690K (Duv 0.0076)
60° CCT = 4802K (Duv 0.0199)
75° CCT = 4713K (Duv 0.0208)

And since it’s gradual it’s less noticeable, still, personally I would put a diffuser.

By the way, with 2700+5700 (50mA) : CCT = 4012K (Duv –0.0075)
And it would be much lower with 2000+6500. So if Fireflies could offer tint mixing that would be great.

For this to work well for photography it will need some good heat sinking to maintain sustained brightness. Certainly it needs to sustain more than the LumeCube’s 650lm which is barely adequate for some use cases.

My guess is with a highly efficient 6A buck driver, and 21 emitters, this should be able to sustain over 1.5k lumens for a long time if you are holding the light (heat sinking), which should be more than adequate for indoor photography. Even my KR4 16x E21A mule is good enough for me to get enough shots for indoor space and I use it very often for work. This will should easily sustain twice the lumens.

Nice design. I’d likely purchase with 3000k emitters.

Now this looks interesting… What color temperatures will be offered?

4500K — Mass production. We have some samples in small quantity available, 2000K / 3000K / 4500k / 5700k

I would be really interested in a 2000K version. Will there be any chance for a custom order?

Sorry , i checked the stock, it is 2700k, NOT 2000K.

[zoysiamo]

I’d like to buy a 3000K or 2000K! (edit: 2700K?)

Tint mixing would be very cool as well. 2000K+6500K or 3000K+4500K look like good combinations.

[SKV89]

Should try to get some 2000k because the E21A 2000K 9050 is very popular. It has the lowest blue wavelength of any LED emitter tested and it actually tests out to be 9080 despite the 9050 rating. It is the closest to candle light we’ve seen. Works well with Anduril flame mode.
