There's a difference between the heat output from a light that uses an open electrical arc (fluorescent, HID) and a light that uses quantum wells.
    Have you ever put both 1000w lamps in a sealed room with idential cooling systems, confirmed they both actually draw the same power (using a kill-a-watt or similar device) and then measured significantly different temperatures in that room?

    I doubt it... but if you have, then can you explain where that equal amount of electrical energy goes if not into heat? (I know some people like to say "light" but that's not a good answer, since it's a sealed room the light cannot radiate away... it must bounce around until it is eventually converted to heat)

    Entropy is one-directional in every configuration. Whether that heat comes from a metal heatsink, a glass barrier, or the walls warmed by radiation, it's all still heat captured in the room.

    I have a fan drawing the heat from the 'sink at the back of the lamp and I pump it out of the room before the room even knows it's there.
    Yes you have a better cooling system in setup "A" than you have in setup "B". However, if the same # of watts had to be exhausted by exactly the same system in both setups, the temperature would be the same. Yours is not an apples-to-apples comparison.

    So your LED setup permits you the luxury of a more efficient cooling system, a legitimate advantage to that type of lighting. apples-to-pinecones comparison, the apples are tastier, i agree.

    The original claim was that 300w induction raises room temperature less than 300w HID. I don't believe it's so unless they're unequal setups. Is there something about induction lighting that allows you to more easily exaust a portion of the generated heat? If so, that's great news. That's why I originally asked the question of how someone got a 300w induction light to warm the room less than 300w HID.

    In way many more setups than you can possibly imagine, and across the globe, pal.

    My job is to design lighting solutions of ANY sort and as acting director of research for a multi-national corporation. That means LED, Induction, HID, Fluorescent, CCFL, even micro-plasma sheet lighting. You probably haven't even heard of the last one.

    Sorry, brah. I missed that part.:stoned:
    In which case I agree with you as conjecture.
    Watts, is Watts.
    Can't say for sure if the lack of internal, hot tungsten electrodes would make a big difference or not.
    So, I'll defer to those who can.

    Have never personally used an induction light.

    So, I'll recuse myself, from this discussion, an' happily take my pineapples, with me.

    The tube itself emits less heat due to having no electrodes burning, exactly, but it still gets hot at higher wattages. The ballast, not so much but it still gets warm, and for induction lamps that is an issue given the typical close construction of the unit, especially at higher wattages. Even so, more wattage in a tube does mean more heat generated, but induction does not run as hot. If it ran as hot as HID, the thin phosphor layer would be vaporized well before the advertised 100,000 hour life.

    khyberkitsune if i get a 40watt induction lamp every 8 inches from each other could i flower some small plants? 5 40watt in 4sq ft

    Just use a 40w induction lamp per square foot, and one in the center of those four? Yes that would work, although I could see that getting rather costly rather quickly. Honestly I'd go with LED, as induction lamps still have some heat issues that need to be ironed out.

    do u think led to support the 40watt induction, i am not rich but i have some money to throw at it and do u know about the 32watt odor control cfls?
    if i use one for ever 2sq ft will that help with the smell

    The odor control CFL lamps are nonsense. They are not as effective as a typical chemical-bag solution.

    To support a 40watt induction lamp... well, a 50w LED lamp in the right configuration should replace both of those lamps. I wouldn't use induction for now until I've had the ability to test my custom phosphor blend and give you a result report. There is the chance that my LED panels are not as efficient as induction, but it's really dependent upon certain physical conditions. As it looks, though, induction is second-dog to LED.

    I have sincere respect for your professional abilities. That is why I am asking the questions instead of simply telling people "no you're wrong". But i'm still waiting for you to explain where that 1000w of electrical energy goes if not into heat energy.

    Or put another way: can you please explain how an induction lamp using 300w of electricity would produce less heat than HID lamps using 300w, if they are both in the same sealed room?

    I totally get the concept that the TUBE of a particular lamp may be cooler. Maybe we are discussing different things?? I am referring to the air temperature in the room, which is what the thermometer on the wall measures.
