@chinakush If you keep airflow on them it cools them quite easily. I have the driver mounted in the center of my fixture and it heats up quick if I have it running near 100%. I put a small computer usb fan on the fixture blowing towards the driver and my entire fixture cooled down.

Most guys use 1" material for heatsinks so I'm sure yours are heating up quick but aluminum cools so easily with even slight airflow across it.

Thank u Danielson , I actually got this type of design and setup of drivers and strips from u for sake of simplicity and price point and I appreciate u helping out with it , I will b adding more fixtures this week to see if I can bring temps up and add a circulating fan to try and get more stable temps in there ! Will b trying 3-4 fixtures in the same space will keep updated thanks again!

just an update all is running and well thank u for all the help, so I'm running 12x 4ft eb strips with 2 x drivers HLG-320A-c1050 at roughly 300w each and they get pretty hot, I'm using 3/4inch aluminum channel from lowes, and the lights and driver get upto 110-125F hot to the touch but they are running sweet i get about 300-350umol at 3.5 feet distance from canopy I have an apogee 200 and will b doing more tests after this weekend with more pictures, at 300w each they are tuned down a bit but if I have them at full blast they run at 335watts is it safe to keep them at full blast ? I'm already seeing pretty good light levels but I'm afraid of running them too hot...not that my room is hot, I have the lights in a 15x10 space covering only a 4x4 area and temps are not hot enough for proper grow temps so I'm building a few more to see if I can get the temps up without using an ac!
I found a cheap DIY to that might help cool your lights.
I follow a grower Lokigro on Instagram He made ceiling fans out of cheap box fans. No rewiring just took them out of the box and attached to his ceiling. Growmau5 make him a beautiful light. That's how I started following him.

Smart on you for having the panda film on the bottom.
Are you running rock wool cubes?
If so, have you tried running batting under them.
So it was a brain fart

Started autos in rw cubes
When to 4inch blocks

Figured there wouldn't be enough room for roots lol dumbass

Put them in pots half filled with clayballs and perlite

What a fucking mess, perlite everywhere
Two different moisture level mediums
Rw gets soggy and clayballs get dry and caked in salt

Roots circling hard at the bottom of the pot

Had my mother's like this too but I successfully twice!! Cut all their roots off flush with the bottom of the rw and Bushwacked 2/3 of the foliage into a bonsai mom and now their looking great.

But I'm being forced to flower these out for the next 5 weeks probably lol

Next run is pure coco in square pots..

Next time keep everything the same but go buy some quarter inch batting from a fabric shop, place it under the rock wool blocks. The roots will leave the blocks and basically carpet the floor of the tray using the batting to stay moist.

so i have been running 10, 3500k 4 foot bridgelux strips now for about 2 months, i have to say, Im not impressed. They cover an area of about 3x4, They seem to be ok if they are just about touching the plants, but once you go a few inches from the strips the light drops off like a rock. I am running them at around 60 watt each. I am really irritated about saying this, but my best results are coming from my Vero 29 cobs, where are way to fn expensive to massively scale out. I have a 2- 3x12 tables and am thinking about selling off all my LED and moving to, (head drops in shame) CMH.

what are you driving them with?

I think one drawback, especially at higher than the 700ma nominal current, is exactly what you are describing....the penetration for larger areas can be considered insufficient.
The intensity does fall off rapidly when they aren't packed together, to get the LUX levels customized to my structure, I had to have more strips concentrated at the 700ma range....
I have the 2 of the MW 240h-700 drivers running 15x 2ft strips each, in about the same area 3x8.
There's sort of a point of diminishing return, having to buy more strips and use less current to get the saturation high enough.

my plants look awful under this light. Sickly and small, i have 36 plants going and the ones under these definitely look the worst, followed up by another lighting method i won't mention. I just ordered a 630w CMH and will see if that will fix the issue. Honestly i think if i like it i may get more of them. My patients is wearing thin with my leds. 5 of my 6 rigs are under preforming. Granted these are all in open areas not tents, so lighting is more difficult here. My veros with were my first purchase ever, seem to do the best, They are running on a hlg-480 -1400 driver. They are running about 65 watts each, i have 8 of them.

I think my problem with my other lights are I am running 10 cobs on hlg-480-1400 drivers so they are running at 52 watts each. I just don't think they are penetrating enough.

I mean, each table is 3x12 and i have 3 rigs running at 525 watts per rig, so almost 44 watts per Sf

Cotton or synthetic?

Man, my lights are a solid foot above the canopy or I burn everything lol

50k+lux straight across the 2x4 table

X2- Hlg240h-24a
X8- 3000k 2ft strips bridgelux eb series 1
X8- 5000k 2ft strips bridgelux eb series 1

Dimmed down to about 70 percent the drivers aren't even hot lol

ultra lemon haze about 5-6 weeks left probably

You could run that 630w cmh driver with two cordsets to vertical reflectors and then use the 600w of strips as side lighting?
