I want to build my led light


#1

@dbrn32 ok I have a 4x4x7.11 tent and I grow 4 plants in a 5 5gal bucket rdwc and I need you to get me a shopping list of all I need for a top shelf light something you would build and use for your self. Also money wise try to keep it under 500.00 bucks. So plz help me


#2

Will be tough to do with cobs on $500. Strips or quantum boards ok?


#3

What would you build with I said try lol not def under 500 lol


#4

I don’t want to have to build another for a long time so if cobs are the way to go then so be it just want a good led for my setup and I know you know your stuff when it comes to led lol


#5

My preference is cobs, but I’ve never flowered under the boards or strips either. I think there are plenty of examples of both that I’ve helped people build that are doing very well though.


#6

Kk I need a cob setup I need a list of everything I need to buy to set it up I mean everything lol


#7

I think you misinterpreted what I was saying lol. I think you could do plenty good with some strips or qb’s, I’ve just never flowered with them.

Lemme go see what hlg still has marked down.


#8

Lol I want a setup you would use lol so if u never used them I don’t want them either lol so cobs and a good driver for it whatever heatsink you req is what I want lol


#9

In all fairness, I shut down my grow about the time qb’s were coming out. The last light I built for myself has a qb on it.


#10

I would consider grabbing two of these and buying drivers separately. If you can build a frame for them reasonably, would probably be in $500 price range, and definitely a kick ass light.


#11

Ok what size drivers lol or what kind. I really appreciate the help I have never built a led light and as far as I know the cobs where best but I can build the frame out of some spare aluminum strips I have they ar 2” wide by 8’ long by 1/4” thick you think that would hold the weight


#12

Possibly. Some like an angle about 1/8” thick walls offers a very solid frame. But bar stock may work if fastened and supported well.

If you order 2 of those packages for a total of 4 boards, you’ll want two hlg-240h-c2100a drivers. Check arrow electronics, they’re offering 30% off if you haven’t ordered from them before.


#13

I have steel angle but I can get it in aluminum and you are saying get 2 of the qb 288 sets


#14

Steel angle will work if you can deal with the weight.

Yes, 4 boards total for a 4’x4’.


#15

Ok I ordered them now for the drivers I’ll order them in a min but now the build do I want them spread out or have no spaces in between each board


#16

Spread out a little. I think @MAXHeadRoom had a real nice diagram to follow for a 4 board build. I’m sure he’ll share if he still does. If not, I’ll come up with something for you.


#17

Arrow is out of the model with built in dimmer. But they have the b model.


#18

Ya I see they are out lol and I want a dimable one right


#19

Those would require you to hook up a potentiometer to dim. Not a huge deal if you want to take advantage of the 30% off. Just click on the blue bar on top of page and fill out info. I had my code within 2 minutes.


#20

Both a and b are dimmable. The a has built in pot 50-100%. The b on the end means it comes with dimming leads and you need to hook up your own dimmer.
