I normally don't use this phase, but my plant move was an unmitigated fucking disaster. Nothing survived the move. I had 24 bato buckets in a 4x8 tent (WAY TO MANY). Everything was so intertwined and searching for light, that nothing was even viable to move to the new area. I am going to have to basically start over. There is a massive infestation of some kind of gnats, I really let nature take its course here and get bit hard by it. GAH!

Just wondering if they make a good replacement for COBS. I mean... Are you getting the Photons? Are they really as good as they seem?

I think these and cobs each have they own pros and cons. I can't speak to the Photons (post a link to them)

What I have in the picture is 10 - BXEB-L1120Z-35E4000-C-A3 - These are 4 foot bridelux strips in the 3500k range. I am running them on 2 HLG-240H-C1050A meanewell drivers.

I use 1/8 thick aluminum L bars. Each LED strip is mounted to a bar, so there is a lot of metal on this unit. I think i have about 46 feet of aluminum total. This stuff is about 1.25 a foot from a local metal supply shop. So $60 total.

The total unit size is about 3x4. If you had a 4x4 tent you could spread the light bars out a bit more if you wanted.

The total cost for this unit will cost you about $260. This does not include wire, wago connectors, junction boxes, 3 prong plug, drill bit, screws and 1x1x48 aluminum L bars. You should figure you will spend another $100-150 in parts. Maybe less if you can find a metal supply shop in your town. Home Depot prices are higher for the aluminum bars.

This unit in its current form can run at about 600 watts. That would blanket a 4x4 tent with light. I don't actually think it needs to run at that wattage in a tent with reflective walls.

What i like about these is they don't require heat sinks like cobs, price wise they are about $14 USD each. They can run at a max of about 65 watts each. You could push cobs harder, say up to 100 watts. But you really lose efficiency.

This is just a personal preference. But i like my lights to have lots of space in them. I want to be able to mount a fan above them and have it blow down over the light providing extra cooling and a nice breeze for my plants.

feel free to ask for clarification on anything.

What size grow area are you trying for?

That's everything i wanted to hear

Thanks friend.

I'm just learning about how the technology is evolving. I'm actually running Cobs atm & very successfully too.

As you've said. Up to 65W and No heatsink. That's like a cheap cob right there. It sounds to me like cobs found their replacement unless one needs all light coming from a single small round spot, hehe
