This chart badly needs updating, but the original poster, LeMoel, hasn't signed in since December 2009. The Luxeon III, V, and K2 are now all obsolete. There's no mention of LedEngin LEDs. And now, of course, we have the insane 10+ Watt LEDs, which, while currently quite a challenge, will no doubt soon be commonly used in sabers.
I'm not sure where the "overdriven" data comes from. Obviously, manufacturers aren't going to include such info in product datasheets.
Anyway, I'll do my part (?) by summarizing the data for LedEngins, which are my personal favorites.
Note that I'm not including such colors as "Cool White," "Warm White," "Deep Red," and "Ultraviolet." Neither am I including LedEngin's multi-color LEDs (RGGB, RGBA, RGBW--because of the complexity of comparing "brightness") nor the 15-Watt LEDs (which do not come in a star PCB configuration).
The Forward Current given is the "maximum" (which is not to say "peaked" or "overdriven"), and the Luminous Flux and Forward Current given are for that "official" maximum Forward Current. Note that the Forward Voltage for the 10-Watt Neutral White is a guesstimate, since the "Typical Forward Current Characteristics" chart stops at 1000mA, despite the fact that the maximum Forward Current is given as 1500mA. I just extrapolated based on the curve. Also note that brightness for the 10-Watt Dental Blue is given in Radiant Flux, rather than Luminous Flux, and since there's no meaningful way to compare the two measures, I left it blank.
