Which is brighter???

[Wong Yoon Wei]

Take note that the rebel blue is more ANH blue than PT blue. Closer to cyan than pure blue. It is however brighter than a p4 royal blue even before overdriving.

You can't really take the Luxeon colors as anything specific, as they are arranged over 6 bins, so there is a lot of variation. The P4's are only 3 bins per color so they are much more comparable.
You should post what bin you were using when comparing colors.

the manufacturer specs are also without a big heatsink on them. the max is then listed based on heat buildup in controlled conditions.

I am using the Rebel Blue from TCSS. What bin is that? To my eyes, it is really close to the blue in ANH which in turn is really more cyan than blue. I believe the general consensus here is that a rebel blue is not as true blue as blue should be.

I'm actually fine with that, as I didn't want a royal blue like in the Prequels, anyway. So, now for the big question- what's the absolute max I could overdrive the rebel? 1.5A? If so, that'd be sweet... And yes, I realize I would need some sort of thermal compound if I were to go this high...

[AndyM]

I wouldn't go above 1.5A personally, and using thermal compound is always a good idea

[Master Valon]

ok, I'll probably go with 1.5, then. I actually might start off with something less, like 1A, see if I like it, and if not, I'll bump it up.
