First of all, I'm new on this forum (but not new on fishkeeping or aquarium on general). But I'm very interested in replacing my T8 fixture with leds and those ebay floodlights seems to be sortof cheap and intensity-efficient.
@heineken(really nice beer actually..)
is it possible that you could provide PAR data also off center, I mean like two inches and four inches away the hotspot right under the led.
What would you think, would I end up with medium light or low light with five ebay 10W floodlights. My tank is 45 inches long and 16 inches wide with depth of 18 inches. I'm planning to fabricate a fixture with those five 10W floodlights spaced evenly on the lenght of the tank.
