    100 Watt LED Chips - Best Quality Brand ???

    CXB3590 is a top choice but if you want to run at 12V you will need a boost driver as most large COB's start at 36V drive voltage, however $60 is a ripoff, much cheaper elsewhere Cheers Mark

    I PM'd you but did not realise you wanted 150 watt, Mechatronix Giga(Passive) you should consider, however for 150 watt you may have to go ACTIVE cooling Cheers Mark
