1. chinezarii scumpe rau
2. se poate si 1$/W fara heatsink.
3. jdemii de watts led pentru ce? un led alb de 1W abia atinge 100lm, dar alea din china nu prea cred.. hpsu atinge si 160lm/W
4. as folosi led sa suplimentez cu lumina rece un hps, in rest nu prea vad de ce sa aleg momentan cand 400w de led(china) ajung sa coste cat un hps de 400w cu balast digital. Iar caldura degajata e cam aceeasi, ba chiar teoretic hpsu ar degaja mai putina caldura pentru ca e mai eficient desi o parte din energie este convertita in lumina infrarosie, de unde rezulta niste caldura iradianta.

nu ma bag la restul dar la pct. 3 nu prea tine.
conteaza eficienta, nu lumina vizibila sau watti..

Ba chiar se poate mai ieftin, 45$ 100w led cool white cu driveru asta 25$ plus un maare radiator sau un cooler cpu si niste pasta termoconductoare si ies 100w de led sub 100$.

L.E.: La 3, referinta.
apoi Cree breaks 200lm/W efficacy barrier in R&D for white high-power LED

ce faci cu leduri albe?? de fapt de ce mai iei leduri daca nu te folosesti de atuul lor, adica spectrul cat mai concentrat exact pe banda necesara plantei..

Completezi spectrul?

cool white led
&

L.E.: Leduri de 630nm&470nm, is vreo 70-80-100$ placuta. Driverul difera in functie de culoare, 25-28V, 3800ma si 30-36V, 3000-3200ma.

Daca esti nebun si cu $$ poti oricand sa incerci asta. Nu vad insa rostul.
