I love this Photino 
It uses the diode I briefly discussed here:
http://laserpointerforums.com/f46/p...-all-op-please-sub-75750-107.html#post1331243
Unfortunately, the diode itself was heavily damaged during my analysis of it, so I had to do some very delicate arctic-silvering of the remnants of the diode into a make-shift module. The cooling is nowhere near as good as a typical diode (like a 9mm diode, etc) pressed into a module, so I decided that it made sense to use the diode in a build that itself would never require long runtimes. The Photino was an obvious choice. Impared as the diode's thermal handling may have been, that became irrelevent when built into a Photino, which isn't intended for any sort of meaningful run time. For reference, the entire completed Photino 465nm build (that's host, diode, cells, driver, module, lens, etc) weights 35 grams (about 1.2 oz).
Driven at 4A (a little bit under the 4.4A I tested it at in that thread), I'm getting around 465nm, increasing to 468nm as it heats up, which it does very quickly. With an output of around 4.5W and wavelength of 465nm, this might be one of the brighter (brightest?) portable blue builds out there. It's a beautiful color and power combination. The build required an entire redesign of the internal driver. The new design is theoretically capable of around 5.5A of constant current, triggered by a tactile switch, with soft-ish start. That said, even 25C 120mAh LiPos have their limits (one of which is, obviously, a ~3A current draw limit). With 2x cells, the buck can handle driving the diode at 4A, but that's probably nearing the limit of this nano-sized form factor.

omg I'll have to change my name to VisibleBlue! Please keep looking for other sources of these!
