    1800 watt cob light

    Very easy to replace the cobs with bjb holders and Citizen 1212 or 1216 (preferred). Drivers are ~36v 1500ma. 4 of them will blow away the original 6 and use 100 watts less power doing it. Converted 2 6 cob lights to 4, very happy. Lux value almost doubled.

    I have 2 chinese "1800w" cob lights. I want to cannibalize and rebuild on 2 3x2 aluminum sheets. Lights use individual ll2250pf 50w constant current drivers. The drivers spec is 87% eff. Is there any reason other than dimming to change them...if so any suggestions? Any idea what kind of...
