    Are leds a lot cooler than hps?

    Anything over 600w to replace a 1k is just plain overkill....i aint met too many phenos that can even handle that much light.

    Are leds a lot cooler than hps?

    Yes , 2 per light is the norm for people that have already found their pheno. (thats not a huge group but plenty) My yields suck for the most part and i have already gotten 2gpw with led, once. I have heard of 3gpw but i cant verify it , although i have seen more then 2 folks claim that. 2gpw is...

    Are leds a lot cooler than hps?

    I dont know what you mean by "two things" but i consider plant absorption and heat , two things. I know what you are trying to say and you are right but its not enough to change temps in a room.

    Are leds a lot cooler than hps?

    Agreed. But i still say a 600 watt led is putting out the same amount of heat as a 600 watt hps minus the ballast. 60% of the hps light goes to the plant....40% goes to heat. 90%+ of the led light goes to the plant ....<10% goes to heat. ALL 600 watts of both lights go to heat. Some lights...

    strip led run hot or soft what layout

    If you are gonna put them on aluminum anyways , then go ahead an put some thermal tape on there to make it a heatsink. The cooler you run them , the longer they will last. Also the spectrum will hold up over years if running them soft. If you could liquid cool these strips then you could...

    strip led run hot or soft what layout

    Yes , mejui is chjna strips/boards. They are the same as my samsung builds. I bought the pre-built lights before i had any clue on how to build them. I have not been able to find 3k or 3500k strips for cheap enough to build my own flower lights yet. ALL prebuilt lights run too hard for my...

    strip led run hot or soft what layout

    27 watts each on the 4ft strips is nominal. So 29 watts each would need a heatsink and would run "hot". You would want to double or triple the amount of strips to run um soft. Double the strips would not need a heatsink and triple the strips would never go out or get hot.

    strip led run hot or soft what layout

    After a quick glance at the data sheet , it seems your gonna want 3 watts per strip ? The data sheet is ugly to me , i cannot comprehend it. it says nominal current 350mA at 19.1volts =6.7 watts. Im not sure if that is per diode or per strip.... EDIT: that info might have come from a 1ft strip....

    strip led run hot or soft what layout

    The more strips/bars , the better it will run. The softer , the longer they will last. When one gets into running them soft , its to save money on heatsinks or to just make um last forever. In a perfect world you would run as many as you can afford to buy @ 800 or 1000w. 800 watts / 28 strips...

    Are leds a lot cooler than hps?

    Imo , the light output of leds are double. 1000hps is easiely replaced with 480w qb boards. I also use bar style lights at 600w each. They put out a tad bigger spread then qb's. Roger explained the heat in real world terms. A watt is a watt. HPS dont actually run hotter, they just have more...
