hello
what will be the led in the DBS V3 ? P7 .? cree MC-E ?
:devil:

I was just guessing, for the time being, the only thing on the horizon for advancements in the "thrower" class of LEDs is increased efficiency of single die emitters. unless someone can come up with an optic or focusing system for the multi-die emitters that throws really well.
So right now they are using Q5s and R2s in various "thrower" lights out there. The R2 is slightly brighter per watt than a Q5, then an R3 might come out, then an R4, and so on and so forth, up the chain. I have no idea when the next "bin" of cree LEDs is coming out. But you can expect that in time, any new bin that comes out, will eventually find it's way into some flashlights.
That is not entirely correct. There is a scenario where the multi-die LED beats the single die. That is if both are in OP reflectors. And the multi-die LED would not need a bigger reflector to do this.Yes agreed. The 4-die leds are not suitable for throw lights unless they have very large reflectors,
but they'll always be trumped by single-die lights with a high lumen output/per area of die.

I forgot to mention what I said is based on running each die at the same current as the one in the single die LED. It can be done but you use significantly more power. I think the MC-E and P7 are more suited to optics personally.Dereelight had tried the P7 and was not impressed.

The gap between the dies in the MCE is worse.

Time to visit the spotlights sub-forum if you need more throw.
