LEDkovy blesk

[Naprstek, Jiri]

Kdyz uz nic jineho, tahle ledka je do blesku urcena, tak by mohla ty peaky alespon nejakou dobu vydrzet. Spektralne je to bohuzel klasicky "dvojhrb" 440nm+550nm, jako kazda bila LEDka.

Koupit v kusovce by (pry v pohode) mela jit tady:

Luxeon ma na webu i par doporucenych driveru. Osobne jsem zkousel jen ten sipex (neb jsme ho meli v nabidce), ten fungoval celkem OK, akorat neumel cely amper.
