stereotypo - nice looking setup. i helped a bud assemble a six lamp PL-L lamp, 55@ tubes same as you. Haven't noticed any issues with heat, but he's got some 70MM fans blowing directly onto the base area of the tubes. I like the even spray of light, and while the next assessment is subjective, i swear it (6 tubes at 55W) throws more light down than another light housing he's got that has six 65W curly tubed CFLS - same size housing (24X24") for both, and both have similiar DYI reflectors fabbed from fiberglass with a layer of the mylar film bonded on the reflector side. But to my eye, looking down at the leaves, with both lamps same distance from plant tops (4-6"), the PL-Ls show stronger light on the plants.
Only problem or complaint, is the interference with AM radio signal. Have you had any issues with interference?
we've tried everything, spacing on the ballasts (fulham workhorse 8s), all wiring is shielded inside a metal raceway or in the alum "panel" box he built to house the ballasts & switches
just curious as i'm considering these for my own grow room (for vegging, and supplimental on flower).
No problems with AM interference that I can see at this moment. I have 6 ballasts with 2 lights on each.
No problem keeping it cool, temps are in the mid 20's all day long. I have a vent right above the lights that goes to the electrical pod and from there it goes to a 4" Canfan then to a filter. I designed this box to grow 2 vscrog mamas.
