100$ is low for a good led build unless you only want to veg indoors then you can get away with less. What kind of space you dedicating to this?

I would start by determining the amount of space you will actually be growing in or the amount of plants/size of plants. Then you can begin to figure out what kind of equipment you will need. What's your budget like?

Need some input on the cooling aspect for the fb24b. I can get a hold of extruded aluminum for free but it's painted. Will this affect heat dissipation? I know the strips don't get crazy hot but rather run coolest it can be. Would sand the mounting surface of course. Figured this would have...

http://www.heatsinkusa.com Check them out can get lengths of extruded aluminum heatsinks from 1" to 75" and have few different widths. It's sold by the inch. I thought of using these for my fb24b build.

I've been liking the strip builds very efficient and I like the even coverage. Can also run them closer to canopy if space is an issue. You can pick Bridgelux EB series strips up for cheap or the Samsung f series strips which are little more costly but I feel it's a much better strip. If you...

Very similar to what I'll be doing. You drive them at the full 2.5a? Can't wait to get my parts and start building.

Very cool how's growth been so far?

@ANC How's flower under that? Only reason I want few extra lights is because I'm running a scrog. Wanted even light distribution.

Nice setup. What area you covering with that? Mine will look similar but 2 strips on a 240-48 total of 4 pairs over 4x4. So they will be 2500ma at max but probably will dim down alittle. Also debating buying 47" by 2" extruded heatsink for mounting just not sure it's necessary.

Hmm read datasheets wrong I was under the assumption that max current was 2100ma guess it's 3600 haha. Well thanks everyone who replied think I got my plan. Now to find all my parts will post again when I finish.

Thanks for the replies. Is it safe to run it that close to max voltage (5 on s 320-1400) and how would that compare running 6 of them softer at 1050ma or 6 on 320-48 running at around 1100ma? Even thought of doing 3 each on a 185-1400. Can buy 2 out those same price as 320. I guess my main...

Yea guess I shouldn't push it too hard. Well if I run 6 in a Hlg-320h-c1050b that will be in better ranges and give me about 290w if I did 2 over 4x4 think I'll have good enough output for flowing? I'm not a 100% on the math behind light.

Hello guys new to the forum been following for awhile now and learned a lot from you guys so far. Still quite new to led so want some input on a build I'm looking to do. Plan on using Samsung fb24b (SI-B8VZ91B20WW) over a 4x4 area. Originally planned 2 separate fixtures with 5 strips each wired...
