On PPF, uMol/J is basically an equivalent to Lm/W, and usually tracks it at almost a 1:1 rate, but for being an instant measurement, which is mostly superfluous. IE, PPFD as uMol/mm^2/s is like Lm/mm^2, AKA Lux. If you have X strips each at Y uMol/J at a given Wattage W (just ignore where the s^-1 g...

What kind of load are you giving it? It reads like you might be under-driving or under-loading things a bit. So, that controller allows overdriving, to 11.5V. I do not know if the drivers respond to direct voltage input over 10V like they do resistance over 100kOhm. Does it show that as 115%? If it ...

Hardware stores usually carry panels for drop in fixtures. You can just cut them to size, and mount them. One of those roller cutting gizmos from the crafts store can make scoring the smooth side easier than just a knife. Then you can use the score as a guide. The trick is mounting them. That depend...

Well, I have changed gears a little bit and am going to test out this gear with growing microgreens, 3 strips to a shelf. Here's the latest build, I just have to wire it up! 20190518_123059.jpg As for the grow tent, I'll probably just pack them tight at 3" spacing and try just the 240W of lighting ...

You should have documentation for pinouts and such, with the controller, or maybe somewhere on their website. I don't see much info from a quick search, as far as details go, but it claims to support Mean Well drivers with 0-10V, and allows overdriving. I don't have one in front of me, but the dim l...

A few randomly ordered thoughts. I grew ginger and turmeric last year, in a coir/compost/bark-fines mix, and didn't even give them direct sunlight. They did great. I was going to add grow lights, but the light colored walls did the job. They get hindered by high phosphorus. Mint, thyme, oregano, and...

3 of those would do. Just make sure to get the dimmers set up first, so as not to run them too hot. 3 480W ones might do, as well, going for 100%+ load, with voltage or resistance dimming.

Assuming it is just a feet, and you are not daisy chaining the wiring, 20 will be fine, but bigger means fewer losses.

If driving low currents, you might be better served by sets of QB132 or QB120, or Atreum 144, to blanket the top of each space (or EB2/3, but that would make for a ton of wiring and mounting work). No heatsinks needed, then, just some ventilation, which largely evens out the cost difference. The den...

Each HLG-120-C700 can power 5 of those strips in series. That will be around 39V. The 60V is per strip, and is a surge/insulation/CYA rating.
