108 lm/w is a bit low. I'd shoot for ones at 150 at least. Those strips are 21w max, you'd need a bunch. Just in case you don't know, take the voltage and times it by the current. 24v X .900mA = 21.6watts max per strip. The higher you push them, the lower the efficiency-lm/w. Definitely can use them but like I said , you'd need a lot . Like 25-30 of them. If I had anymore 09's I'd send them. Good luck man. If I get a notification on a sale I'll post it here

Thanks I grabbed a few, found a promo code first though.
So they're back on sale or on sale again. The q series was not on sale when I looked today

Yeah I think someone got in quick and scooped the lot, they were all gone not long after I posted. Not surprised though, they were discounted by about 75%.
Nice find on the promo codes. That one expired, but I used 12OFF, and got... 12%... off.
Grabbed a few of these VLM60W/48V for $3.83 for 60W, no dimmer, two prong input. 93% efficient.
These Autecs constant current 590mA too... $8 for 60W, dimmer, three prong input. 92% efficient.
Should be able to fit 2 x 4fts or 4 x 2fts on one of these.

I'm having trouble figuring out a mounting solution for those, I grabbed idk how many of the 24v version.

Have you tried double sided tape? Could be a good solution. That's how I mount my strips as well. But once a strip is glued down it stays forever lol.

I mean for the vlmxxw-xxv-s. The wiring and mounting posts are on the same side of the driver, with not much space between wires and posts

Ya I am saying just stick the driver down to the fixture 3M tape. Are you saying the wires are in the way of the screw holes on the ends?

Samsung F-Series Gen 3 1120mm 3000K Single Row -144 Diodes $3.32, at Arrow. About 200 left. 85% cheaper than Digikey.
FYI These are basically 1/2 an O.G. Quantum Board per strip, same LM561C diodes. If I calculated correctly, 12 of these @1A/600W will give about 100K lm, /1500PPF, perfect for a 4x4 at around 2.5 umol/j before driver losses.

Thank you for posting this. I just finished using a few of the strips I ordered to build a 300w (at the wall) light for a 2x4. Can’t wait to try it out.

how many would i need to do a 4x4 build?

Nice one, recently finished a similar looking build with these as well, 30 strips and 800W of drivers for a 5x5. Used a lux meter and the MIGRO calibrated conversion chart and was getting roughly 700-800 PPFD in the corners of the tent at about 1.5 ft, heatsinks barely warm, strips being run about 1/3rd of max with remote drivers, which is great during summer, and come winter time I can put the drivers back in the tent and remove half the strips so they run hotter and warm the tent a bit, or add another driver and increase the size of the grow area.
BTW the strips are back to about $18 each now glad we got em' when we did!

*Unfortunately those strips are not available at that price anymore at Arrow.com
Always peek around arrow when this thread gets pinged, really about the only time I look these days. Found these though and ordered a couple yesterday, still showing 3 in stock, the same as when I ordered yesterday but figured may be worth a shot to try and order some if they work for anyone.
Seems like they are a little under half price at $23.
