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

Agreed, but on the other hand, photographer aren’t strangers to gels and filters to adjust the tint and color temperature of an auxiliary or fill light.

plus, optisolis has zero tint shift across the entire beam. an e21a has plenty of it, beyond, say, 120deg it is totally green. it is much less of a problem than with popular domed leds, but as soon as you notice it, it is annoying.

Optisolis has much more tint shift than the E21A. I have to use dcfix to smooth it out when used with reflector.

To add to my previous comment about tint shift, here is 2700K :

Bare e21a 2700K (50mA):

0° 2509.0 Lux, CCT = 2837K (Duv –0.0018)
12.5° 2433.6 Lux, CCT = 2825K (Duv –0.0016)
25° 2338.6 Lux, CCT = 2799K (Duv –0.0010)
37.5° 2138.2 Lux, CCT = 2766K (Duv –0.0001)
45° 1721.7 Lux, CCT = 2743K (Duv 0.0005)
57.5° 1280.8 Lux, CCT = 2706K (Duv 0.0013)
70° 801.9 Lux, CCT = 2659K (Duv 0.0022)
80° 404.0 Lux, CCT = 2645K (Duv 0.0026)

So it is highly dependent on CCT, maybe it is also the case with optisolis ?

Sure thing with a reflector it does, but here we are discussing the mule, and in a mule it has zero

actually, in warm leds the tint shift is by far less unpleasant than with neutral and cold whites. I had a mule with a 3000k e21a and was very happy with the tint. With a 5000k e21a it was no go for me

4500K please. Perfect!

RGB

Personally I don’t care about aux lights much but I really like the extra large mcpcb. Will have really good heat sinking!!! :+1:

Soldering looks very poor and unprofessional :disappointed:

I 3 am interested 4 this info. Many new anduil lights in FF dev, but mum is the current word in regards to version.

I wonder if its just get er done quailty for the protype (hopefully)

This is my strong suspicion. Truly appreciate their willingness to share prototype pics that could be less alluring than the production unit.

This looks to be ideal, interested in getting 2 lights in 4500K HCRI for photography.
I’m no familar with the E21A, would like to see real world beamshots.
I like the rosiness of the 219B 4500K 9080 and am hoping this is similar.
Impressed with the driver efficiency!
Any estimate on price?
Thanks!

Look pretty good, right?

This is a mule so there will be no beam; basically an almost 180 deg wall of light.

E21A is not nearly as rosy as 219b. It is very neutral which should be ideal for photography.

Actually, it depends. If an E21A emitter is driven at below 100mA, it tends to be looking less rosy, but above 500mA, rosiness kicks in more pronouncedly. Above 1A, it is definitely rosy.

The rubber diffuser of NOV-MU is back and works good

will this diffuser survive high temp?

yes , it can sustain 240 degree C

release before christmas??
