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...
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.
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...
Id love to build someone a custom light. Parts are just so high ever since the arrow spike. I got that urge again so im gonna be building myself a couple 1k hps replacements. Gonna start hunting for parts now.
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...
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...
I use the mejui bar style leds. labeled as 650w each. i have two for flower.
I have built at least 6 other lights.... all my veg lights and a friends veg light and some houseplant lights. I have strips superglued to pvc pipes doing great still. I LOVE strips!
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.
