Do u ship to Australia mate?
9 @75w is right in the range of an HPSHow many cxm22 are needed to replace a 1000 watts hps?
If you were to build one how will you do it and what would be the cost?
Thanks in advance.
its about 700W with drivers and puts off as much heat as 700W of any other type of light - but it gives you as much light as a 1000 HPSThats mad and i bet it only puts off the heat of a 400w hps for 1000w equivilent
Same heat output. 700w is 700w. COBs will displace that heat output better, mainly because of how spread out they're.Just throwing this out there, would running 9 COB's at 700watts with active fan cooling run cooler than 700watts of HPS?
see there are 3 options here passive fin, passive pin and active cooled, so i would imagine there would be some varying degree of heat output one would imagine?
Thanks.yes as long as they are both gen 5 or gen 6. electrically 80 and 90 cri chips are the same, the phosphor layer is the only difference. same for different colortemps as well (3000k, 3500k, etc)
gen 5 part number on the chip starts with an H (like H121230M2)
gen 6 start with a T
The way I have understood it (and i could be wrong) is that heat output from whatever the draw is entirely dependent on efficiency.Same heat output. 700w is 700w. COBs will displace that heat output better, mainly because of how spread out they're.
on the backside of the chip, but all that light is getting absorbed in the tent/room and also turning into heat so total heat load is the sameIf for example your driving 500w into a light that is 25% efficient then you will need to account for 375w of heat. Conversely a 500w light with 50% efficiency would require 250w of cooling power.
