Thank you sir.
Thank you sir.
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 hereSo looking around some more, I have found these strips. What about this, will this work ?
SI-B9U171560WW, The specs seem right, what might I be missing? I am trying to light a 4x4 tent.
Thank you in advance
The q series was not on sale when I looked today
I'm having trouble figuring out a mounting solution for those, I grabbed idk how many of the 24v version.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.
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'm having trouble figuring out a mounting solution for those, I grabbed idk how many of the 24v version.
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 postsHave 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.
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?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
What is that?oh yeah these. I usually drill a few holes to mount it nicely. But yeah, not ideal.

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.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.
how many would i need to do a 4x4 build?Samsung 2ft Q-Series LM301B 3500K $2.49, only 125 left!
