Friends in the neighborhood of hydro. Great for coco, not so good for RDWC.Doing some research on brewing tea for hydroponics anyone can point me in the right direction?
Not in my experience; it took two of them to make the same heat as one 600W HPS.I'm using two 315"lec"s and two 600. The lec"s still produce heat just like a 600.
The difference is the lec's don't put off much IR to heat the plants, so they are cooler than hpsI'm using two 315"lec"s and two 600. The lec"s still produce heat just like a 600.
Agreed. This is my experience too. And good advice for a new cmh buyer. It was as hot or hotter than my 400w metal halide.With HID lamps...hps..hps de...mh...cmh..they almost all produce the same "watt of heat". A concentrated point source of heat. Generally...a room packed with equivalent wattage of any of em will usually require the same btu rated air conditoner if they arent enclosed air cooled reclectors using duct and fans. And depending on where you live (outside weather a1md seasons)...how many lights your using...and how your air cooled ducting/reflectors and fans are setup...you might (almost always) still need air conditioning with air cooled hoods. Albeit...not as much.
They actually do, I've personally checked it with a Lighting Passport.The difference is the lec's don't put off much IR to heat the plants, so they are cooler than hps
Not exactly sure what you mean, but I don't care what the Passport says I can tell by the reflectors heating up. With a lec the reflectors hardly heat up with a hps bulb they get too hot too touch.They actually do, I've personally checked it with a Lighting Passport.
They put off half the heat because they pull half the watts.
You're also comparing reflectors taking 600watts with ones taking 300. Less watts is less heat.Not exactly sure what you mean, but I don't care what the Passport says I can tell by the reflectors heating up. With a lec the reflectors hardly heat up with a hps bulb they get too hot too touch.
Ok. Then you don't care about quantifiable evidence.Not exactly sure what you mean, but I don't care what the Passport says I can tell by the reflectors heating up. With a lec the reflectors hardly heat up with a hps bulb they get too hot too touch.
Don't confuse him with facts, he clearly doesn't want to see them.You're also comparing reflectors taking 600watts with ones taking 300. Less watts is less heat.
That's because the lamp pulls half the watts.When the facts are that the top of the reflector get very hot but the rest of the reflector is barely warm and when a hps is used the tip of reflector is too hot too touch i believe that fact not the instrument. Any metal nearby is heated with the hps not so with the lec.
Maybe this will help- take a fixture and run at 100% and check whatever heat/area/ pot of gold you choose, day 2 run said fixture at 50% (1/2) power and test the same area and you'll discover something really amazing.When the facts are that the top of the reflector get very hot but the rest of the reflector is barely warm and when a hps is used the tip of reflector is too hot too touch i believe that fact not the instrument.

a 400 hps heats the reflector MUCH hotter than the lec, but that pesky fact you ignoreThat's because the lamp pulls half the watts.
But you know, facts. Not to be believed.
