well i seem to have done pretty well before doing vertical.
if you want my opinion of how the math works out.
A 5x5 tent with 8 plants in it, 5 gallon buckets, about 1 ft diameter each.
so from the stem on one across to the stem on the plant on the opposite side is 4', some stuff could be closer, some stuff farther, but thats the average.
stuff might tend to favor the inside, closer to a 3' circle.
circumference of a 3' circle is ~ 9.5'
2-2.5' vertical footprint of usable light because the light doesnt have as much distance to spread as the plants are a little closer.
so its easy to see that you can get at least 18-19 sq ft of prime location, and maybe as much as 23.75 or so sq ft.
so if you remember, i like to use cool tubes. thats a lot of air flowing over the bulb.
havent noticed any problems.
with no reflector, the light is less intense.
less intense means you can have the plants closer than under a bulb with reflector.
closer means the light that is being produced by the bulb does not diminish as much as if it traveled farther. this is a big part of where the efficiency comes from in my opinion.
add in the cooltube and i can safely have the plants 15" from the fixture, 1.5 ft from center,(6" cooltube).
