Its a small veg tent (500mm x 500mm x I think a meter from memory). The strips will replace a 130w CFL. In summer anyway, I may have to use the CFL in winter for the heat it generates.Nice! Looks like a pretty sturdy construction, what size space are you going to be lighting with it?
Thanks, I thought it may be better to over engineer the frame and have it so everything can be easily taken apart (and its easier to build lol). I would of preferred aluminium for the sinks but galvanized steel was easier to source and at 50mm wide a good size.Question, where is the fifth strip? Also, looking goooood
Looks professional, good to take the extra time and get solid end product. I'll be making slight adjustments to mine after this grow.You guys are way ahead of me, time to kick it into 2nd gear!
Here's the start of my first panel (of 3 total) ... hit the heat sinks with some 240 grit, followed by some 600 grit. Probably going to use tape anyhow, so doesn't really matter.
Going to mount the strips and wire this up and do some PAR measurements to see if the 8 strips are going to do the job... then neaten up the wiring. The sinks are mounted to some 24" long 8020 extruded AL strips I had laying around. I can squeeze two, maybe 3 more strips on there if have to.

That looks really pro!Alternating 3k and 4k. Time to hack together some wiring.

Thanks. Got a lot of 8020 extrusion, might as well put it to use.That looks really pro!
Looks great. Solid, simple design.
Question and stealing this pic to help explain.the skinny drivers are fine and are actually pretty comparable in efficiency to your typical meanwell. they sit at or above 85% and you can select 4 current options. .335a (45.5v), .39a (46v), .45a (46.5v), and .5 a (47v) options. take your pick how you choose to build if you go for a meanwell driver.View attachment 3972927
yes, lowest setting. should be visibly the dimmest of all 4 settings.Question and stealing this pic to help explain.
The switches in the pic labelled 1 and 2. In this pic is this at the lowest voltage? (both switches to outside position).
lol still tidier than mine..can tell I'm not very anal...Ill post this as a study in what not to do... I've done much better in the past. Haha

Not sure why you are not happy with those numbers - 500-1000 is considered the sweet spot.Unimpressed with the #'s so far, not sure of the correction factor for the SQ-120, but assuming x 1.0
Roughly center of fixture
Distance | mV | PPFD
20" 96 480
16" 114 570
12" 141 705
6" 226 1130
Looking for 800+. Bet the numbers go up a bit once I get another 2 fixtures in there.Not sure why you are not happy with those numbers - 500-1000 is considered the sweet spot.
