CREE 5W

First it was Lux 1 as the king..then Lux3 and Lux 5

Why is there no Cree or seoul 5w?

Imagine 4 Cree dies on a single emitter package

Or a Cree driven at about ~1500mA's.

You forget it is P4 to Q5 to R4 each with higher lumens and varied color block.:huh: Im still waiting for my Q5 228lms cree to mod my torch.
:thumbsup:

So why only a 3W ?

Did i get this wrong or is the Power of a LED only limited by the produced heat? So a Q5 would be able to take more Power since its more efficient.

Well, from my observations, I see it like this.

3W = bright light
4W = really bright light
5W =

Actually, in my experience, you can run Cree's at 5 watts, not too sure how long they'll last. Seoul's can't take that much overdrive without complaining. For me, the Cree has too crappy a beam at whatever level and the Seoul's just can't take the heat in the 1200-1700mA lights I'd like to use them in.

If your question is why they haven't come out with a LED designed for 5 Watts, I suppose they just aren't there yet. I'm sure their working on it.

The lumileds LuxeonV (5w) was just a way to get more light out of a single package at the time. Now we have more efficient LEDs so no need to stuff 4 dies in one package like the LuxeonV. The luxeonV also has a shorter life and 2x the voltage requirement of a normal single die led. Also since it's series/parallel setup there is the risk of a die failing due to vF miss match. They could of gone all in series to avoid this, but the voltage to run the led would be 4x of a normal led.
