Before I start ordering parts for my diy led panel I thought I would ask whether anyone would do things differently... either less wattage or more wattage is the basic question. They say 50 watts per square foot, though that number might relate to LEDs a little differently. For reference the new A51 190 watt lamp at a conservative footprint of 2'x3' provides 32 watts per foot. My design will put out 51 watts per foot. This is my first LED venture so I don't really have a point of reference. Thoughts?
