Has anyone here ever used 70w HPS security lighting? You can get em cheap ($35) and with a little electrical knowledge they can be wired for remote mounting of the ballast.
I like to use multiple reflectors for different plant heights and think that these may make better sense than cfls as a main light source for 4 plants in a 4'x3' area. Although, I would still like to use 5-42w cfls dropped in the canopy for side lighting.
With 4 of the hps and 5 of the cfl, the total would still only be 490 watts consumed but, with an output of 40,000 lumens. All of which could be kept right up close to the plants.
Plus, I can get both the hps and cfl bulbs for $5 apiece.
Using 150cfm of airflow and remote mounting the ballasts to a steel panel outside the room, it should make a very efficient setup for 4 plants.
Whatta ya think?
