am tot cautat prin comert, si nu am gasit. as prefera una construita, am primit si o schita de la Luminus Devices, am postat mai sus, dar nu stiu cine poate sa mi-o construiasca. eu nu am nici un fel de cunostiinte in domeniu, si pare greu de invatat :)

eu din cate am inteles: pentru a scoate valoarea maxima de lumeni, trebuie sa il alimentez cat mai aproape de 21 A. intenzionez sa pun LED ul intr-o sursa de lumina, deci am sa-l pot raci cum trebuie. Am nevoie de toti lumenii.

Am intrebat daca e corect... :rade:

Cred ca cel mai bine e sa spuna tipul exact.
