Correct me if I'm a bit off. I just kind of learned this myself.
1. The 6500k bulb and the 2700k bulb have the same spectrum.
2. The 2700k bulbs are made with an inside coating of phosphorous blocking wavelengths leaving a greater percentage of red light.
3. We used 6500k fluorescent bulbs due to intensity. They had no inside coating.
4. With LED's 4,000k/5,000k have the intensity that we need for veg.
my 600h arrived yesterday and i plugged it in at full power in the living room and my place lit up like there was some kind of alien abduction going on. left my girlfriend and i seeing spots for a while.
will probably use the 600h at ~500w or so at most in my 4x4.
got it into the tent tonight but there is nothing in there currently. have seedlings and clones going in there as soon as they're transplanted in the next week or so, but it made the tent hard to look into at 620w.
i will post updates when they've been under it for a week or two.
everything in veg is loving the little qb65 so far.
moved the plants from the small tent to the big one so they're under the 600h now.
the first pic of the panel itself, the lights are @65w. the photos below that were taken @50%, 310w.

greenpoint's tomahawk and cookies n chem. transplanted last night so the plants haven't adjusted to all of the new room they have. they're still pointing in weird directions because they were fighting for space in the small tent. the larger plants are some rainbow jones moms that got rootbound in solo cups. threw them in as insurance just in case the male:female ratio is shitty.

i'll try to continue updating the progress under the 600 as i go.
You won’t see a difference in temps as you’ve replaced 600w with 600w,but you will see a big jump in yield as the light is way more efficient.nice grow!
That's a contradiction, a more efficent light produces less heat and more light, so the temps will definitely be lower than with hps.
Cheers
No 600w produces the same heat whether it be h.i.d.,l.e.d. or a toaster.The hps light produces ir which is heat the plant can’t use.the led does not,meaning that your plants receive more par light.
