Best Value LED lights for a 4x4?

[Bill Lidgate]

I'd buy 12x Samsung inFLUX L09 strips (SL-B8T7N90L1WW, $27.295 each at Mouser) and 6x Mean Well HLG-185H-48A ($23 ea at BG Micro) and have 800W at the LEDs giving 110,000 lm at 137 lm/W with no BS dimming for ~$500 delivered,
spend the rest on good wire, screws and some stout Al rails to screw the strips to and enjoy some VERY happy plants.

What is the fV of these? Each strip is like 10k lumens?

Hmm, I'd go with 8x Citizen 1825 @ 2100mA and umm 4 of your drivers running at 52V. Same price, more light, less spread. Damn that is cheap as hell.

Also, how the hell can you cool 800W with aluminum rails...that's where you win by a country mile, but I've asked that question before and gotten no answer.

 

[JorgeGonzales]

You'd need about 4 x 22" lengths of this just to fit the strips, with some 120mm fans for airflow, at least if these were cobs:

I've built mono diode lights, used the same big assed heatsinks, but that was a lot fewer leds than smd strips.

You can get the almost identical 1st gen models for $11 at verical instead of mouser. Also, the strips based off of the lm301a chip are even cheaper.

Check out these-http://redbirdled.com/resources/RedBird%20LED%20Stripit%20Kits%20155%20NG%20spec%20sheet%200915.pdf
They come with the driver and come out to about $2 a watt. They maxed out my par meter at 1". They are 44 watts per 42". I have 2 of the 2' footers but I haven't had the chance to retest them, but they are bright as hell.

Hey those are sexy. Where did you buy them, or are they samples?

 

[nevergoodenuf]

Just give them a call and mention this forum. I have talked with Steve a few time. I think they were around $80 shipped and price drop at 10.

Almost plug and play.

Dude that's dope. I want to like my heatsinks with these. How many can you put on a 1.05 amp driver like that? & how many lumens are each strip?

 

[Airwalker16]

Edit^
Oh nvm they are pre built into the t slot. I need a good remedy for some strips I can fit onto my 36"x6" heatsinks and can all be placed on one driver. Maybe like 6-8 strips with some kind of adhesive backing or something easily mounted with like Stevesleds 1 part thermal glue.
I either wanna use white leds or a combo of red blue white. Any ideas?

All of the response has me asking more questions..

Should I be using the samsung strips instead? A 1000w HPS puts out roughly 145,000 lumens, which is what some have said is perfect for a 4x4 along with good airflow etc. The CreeCXB3070 puts out 8500 per cob. So I'd need 16 3070's??

You can put cobs in a much more spread out pattern. So you need less of them. You could run 8 cxb3590's@ 1750mA and kick ass.

I'm new to cob lighting, would i need one of those patridometers or whatever they're called to change the mA

Lumens don't mean anything.

I am pretty sure I gave an amazingly awesome answer already. I say this not to pat myself on the back, but because I almost don't believe the numbers.

6x 1825 3500K and 3 of the drivers Bill linked would be about $300, and make ~1400 PPF, somewhere around 940 PPFD before losses. I mean, come the fuck on.

Cooling 100W a cob is another story entirely.

Have you thought about buying a light, or going DE HPS?

 

[Feisty1UR]

I wanted to build my own cob lights, I have the money for it. But I'm unsure on what I'll need. I know the basics, cobs, cob holders, drivers, heatsinks, etc

I have no clue about ppfd, something about light spread?

Yeah I was going to buy a DE HPS, 1000w would raise alot of suspicion. Don't want the leccy company catching on.

You are still going to need about 600W. But hell, my fish tank used to use that much.

This didn't help me at all.. all I got out of it is. Spread light fixtures = More ppfd, So I'd need 4000ppfd for a 4x4??

I'd buy everything now if I knew what to get.. someone help this is driving me insane
