Vincent - Good point. I would agree with you if not for a couple of things in this case.
I'm definitely no LED expert, but at first, even with the lithium's it was still greenish looking with no blue. It's been my most often used light over the last couple weeks now, but it has also been compared to a couple others throughout that time for reference, as well as many looks against varying white surfaces.
Whereas there previously was no blue at all, and not even much white, it's now white with a hint of blue. Any other lights in the house have remained consistent in their color.
I'm just wondering, if like Lux's, these also go through a Vf reduction during some initial amount of burn-in time, effectively causing a higher nominal current draw. Especially when driven to spec or slightly overdriven. They are, after all, 5mm LED's pumping 100ma as compared to 20 - 30ma for conventional 5mm's.
Mags - Again, not being "da LED man" by any means, I'd say all the hoopla is the fact that they really are pretty darn bright for 5mm. And my guess from what I'm reading, is that they are definitely brighter than the 26,000mcd's, while also having a much wider beam angle thanks to the Mike Jordan grind and polish job he does on them. I don't have any 26,000's to compare to, but the MJ's are bright little "dark suckers" when driven properly. The side emitter-like properties of the grind job make it work well with a reflector.
EDIT: just saw a closeup of die size comparison between the MJ's and 26,000's at this thread.
