hey bud sorry to be a pain could you give me the main names with regards to led's to look into in your opinion, i know you wrote them somewhere but can't find them...yeah true watts
there are a lot of companys that say 1200w
2000w
850w etc
but when you look at the specs.......1.5a draw
well that ain't 850w
an important side note
because quality LED's are much more efficient (lumens per watt)
when you get say a 600w LED
if you compare it to an HPS
the LED is putting out something like 40% more light to the canopy while all that light for the HPS is converted into heat
so for instance
a 600w hps eye horti is 30% efficient
that means it puts out about 180w to the canopy
something like a Chilled is about 50% efficient
meaning a 600w light is putting out about 300w to canopy in the way of light
"Par Watts" which is about equal to a 1000w horti
so that is why good company's like chilled or Spectrum King can claim = to a 1k
because par watts to canopy IS equal to 1k
I am running 3oow of Cree COB's
my lights are 50% efficient
I am hitting my canopy with 150 par watts
with a ppfd of about 850
that would be equal to about 500w of hps
there are a few things that something like chilled and SK have over COB
they both incorporate UVa and IR into their lights
which help in plant growth to allow the plant to exibit more of its true genetic potential
another reason why I would choose one of those lights over say a COB or Quantum board
they are more than just white light
they are "boosted" white light
and with Chilled....being able to enhance red or blue spectrum is an amazing tool to have on hand to be able to really push your plants performance to its limits
IMO
