I like the round die, but I can’t see myself putting that in anything. There comes a point where i don’t think it should even count as white anymore. How does it compare to the green osram? With a green filter it might be useful for hunting…
No, it is nothing like the green osram, if you look at the spectrum there is enough of most wavelengths to make reds look red, greens green and blues blue. Not all great accurate enjoyable saturated colours over the entire spectrum but it definitely is a “white” led. Same with the current LEP lights: extremely cool and low CRI but they still do the job of showing the colours.
My main complaint on the green osram is that it isn’t really that green. I forget what the cri is but I think it’s half way between green and a low cri white. My maxtoch l2k actually has pretty good color for a LEP once you get out there a bit. Up close it looks bad, but nobody uses a light like that up close.
I had high hopes for the yinding, but it doesn’t really seem any better than the pm1 all things considered.
Thanks djozz! It’s interesting that the peak lumens is almost exactly at 8A. Most other emitters peak to the right of their rating.
I think the LED is good enough where I’m going to pull the trigger and pair with a 8A driver and the empty C8 host that I have. I’m going to buy the 5000k version and hope it isn’t as green and the CRI is slightly better.
Thank you so much for the test Djozz. It is greatly appreciated. The performance is surprisingly good. The tint is unfortunate, especially since the Cslpm and Culpm LEDs I have seen have had surprisingly decent tints. I wonder what the odds are that we will see better tints?
Thanks djozz for the test! I’ve been dying to see the results as my three ‘5000k’ emitters are stuck in transit, likely to never be seen again.
The tint is pretty intensely green. I wonder how much of a hit it’d take in flux to drop the duv tenfold if it hypothetically came in another bin?
If mine ever show up, ( In Chicago now! ETA is Saturday… ) I will try them in a bunch of lights. The round die is super cool. Also, the Vf is perfect for true direct drive… My favorite way to run a dedicated thrower.
@Djozz Did you purchase the cool white or neutral white?
Interesting that they rate the 5k as having a slightly higher luminous flux compared to the 6k, we usually see the opposite. I wonder if the 6k would lean more towards blue than green (and if that’s an improvement)?
I’m thinking this is the case. Because of the lumen/w advantage of thee green wavelengths, the green heavy phosphor likely increases the lumen output over the cooler version (more blue, less green). Since they go so light on the red phosphor, the radiant power losses of the phosphor conversion are more than made up for by the lm/w difference.
I have one on a 20 mm MCPCB, 2 bare. Looks like the Vf is slightly better than a XPL-HI so may be hard to get to 8 amps on one cell, FET driver.
Trying to decide what light - thinking of a FT03 but also considering a WT1M. The lumens output is disappointing but that's not the point with this LED. Still, how could they rate it at 3024 lumens, not 3020 or 3000 but 3024, where at best it does about 1800?
I was hoping it would beat the SFT-40 in lumens and throw, but we'll see how it does in throw.
Enderman - What is a circle die mod? Is that JB Weld? I know it must work because you wouldn't do it if it didn't
