Nice pics. Would be interesting what kind of beam
this LED would have.
I would like to know that too. Unfortunately the datasheet doesn't specify which bins they use, but I've been toying with various combos of the highest bins offered for red, red/orange, amber and green rebels. One thing I learned is that if the three rebels are driven in series, the green rebel will dominate the output as it appears to be about 4-5 times as bright as the reds to the naked eye in the 100-500mA range. Red and red/orange rebels appear to be about the same brightness and appear 2-3 times as bright as the amber ones. Understand that this is all very unscientific and I am just going by the seat of the pants perception of relative brightnesses here, so please don't crucify me, but I just find it amazing how much brighter and more efficient the green rebels, and green LEDs in general, are compared to the rest of the pack.
Here I was trying to make a composite yellow made of green and red emitters. I have two clusters of 4 rebels each. Everything is driven in series at 350mA. The right cluster is made up of 4 amber rebels (LXML-PL01-0030 30lm) and the one on the left is made up of 3 reds (LXML-PD01-0040 40lm) and one green (LXML-PM01-0080 80lm). It may not be clear in this picture, but the one green rebel (third emitter from the left in the left cluster) outshines the reds and ambers combined. And it does this while it has a lower Vf (about 2.4V) than both red and amber ones (2.5-3.2V). I found through trial and error that combining one green and five red rebels produces a nice warm yellow tint, about the same tint as an incandescent 1W or so night light, maybe a liitle more yellowish and much, much brighter of course. So if anyone's interested in making a really, really bright and efficient yellow flashlight with absolutely no focus, well, here you go.
