if i were to get LPC-815 Red 630-660nm Long Die Open Can diode and place it into a module and i wanted it to run at 430mA with a micro drive laser driver. would it run of 3 1.5 aaa bateries? if not what is the best input voltage? and which host would fit the battery needed for this voltage?

here is the info on the diode form blu rays post

The Red LOC module will have the LPC-815 Red 630-660nm Long Die Open Can diode, harvested and install in an AixiZ module with a driver set to 430mA, giving out approx 240-250mW or what ever range you like.

will i need a heat sink?
can i push the diode any harder if i use a good heat sink.........how many mw

thank you all

430mA is too much for those diodes. It won't last very long at that current, regardless of heatsinking. A duty cycle will help make it feel like it is lasting longer, but I'd bet you won't see much more than 20-30 hours of total operating time. Pretty much all laser diodes are rated to last 10,000 hours or more, as long as you don't overload them. Personally, I recommend no more than 350mA for max lifetime, but I doubt you'd see anywhere near 10,000 hours even at that current.

mate i realy dont understand values....

350ma......will it affect the mw? what do you recomned and

how many bateries will it take < important question
