Hey all, I just wanted to share with you my new toy. With the Cree SF's coming out, I was feeling a little down that my L6 was going to be obsolete. That's when I found out about the Cree mod that CPF member CM was doing, so I decided not to be left in the dark! This is a P4 Cree with its bias bump up to 1A.
Here are the numbers that CM gave me:
The total output (bouncing the light off the
> ceiling) increased 69% from
> 9.8 lux to 16.6 with the Cree. This test was
> performed by placing the
> lightmeter on the counter in an interior bathroom
> (no windows) and
> measuring the reflected light from the KL6 placed
> about 6ft off the
> ground shining the light at the ceiling.
>
> The second test measured lux at about 3ft distance
> Total lux increased
> 196% from 2740lux to 8100lux. This is expected since
> a single emitter
> has a tighter beam compared to the four emitters of
> the Lux V.
> You should get over two hours on 2x123's and
> probably about the same
> (maybe less) as with 2xRCR123's. You can run these
> with up to four
> 123's, and 3 lithium ions with a corresponding
> increase in runtime. I
> estimate about 3 hours with 3x123's and 2 and a half
> hours with
> 3xRCR123's.
Control shot: ISO800 F3.5 1/100sec. I had ambiant light in my room just so that there's something relative to compare with. It's a 21W compact fluorescent bulb in a desklamp.
At 10 feet, the hotspot is a tight 5". AW 2 x 17500.
Compared to a SL TL-3 also on 2 x 17500's. The Cree KL6 is WAY more powerful than the factory Lux V, but the TL-3 is simply a beast.
2 stops underexposed. ISO800 F3.5 1/500sec
I am very impressed with the CM's craftsmanship. My L6 now throws a sharp needle of light with an extremely powerful spill. I'm thinking about getting a Leef body and putting in 18650's.
