I have come to the obvious conclusion, that the easiest way to keep heat down would be the electricity. So if anyone has some experiance on the subject, what bulb puts off least heat. Hps, Cfls, or Mh?
But those components give off heat right? I mean, if they didnt there would be no reason for vents.You can put your hand right up to them, you won't discern any heat. The vents and fans are for the electrical components inside the panel, not for the bulbs.
How would you explain 2 150w cfls heat vs a 300w MH?My understanding has been that a watt is a watt is a watt......all put off as much energy as the next.
I would have to call bs on that. with remote drivers, nothing but solder on a drilled heat sync with diodes and optics, they will still put off heat. It's just not much. For a 1.5 ft^2 unit 2 cpu fans were able to keep the heatsync surface temp to within 1 degree of room temp, so it's not a lot of heat, but they do put off heat.You can put your hand right up to them, you won't discern any heat.

to start, a 150w CFL is probably drawing ~75 watts at a power factor of .5 (this power factor was pulled from a search on google for 'CFL power factors'). So to properly compare heat, you would need to compare 2 300w rated CFL's (drawing around 300w total, testable with a kill-a-watt meter), and a 300w MH. Both produce roughly the same heat (MH ballasts consume energy as well, and will radiate heat...). As I said before, the reason you can grab your CFL and not your MH is because your CFL spreads that heat energy out over a large surface area. They are a diffused light source. MH's are a point source, the same amount of heat energy in the CFL's broad surface is concentrated in the MH into a small space.How would you explain 2 150w cfls heat vs a 300w MH?
Not much light either, LOL.LEDs put off no heat.
It is the number of LUMENS per watt that we should be concerned with.My understanding has been that a watt is a watt is a watt......all put off as much energy as the next.
