XLG drivers offer a cheap solution for these boards. With the XLG-200-H-Ab, you can get them to 4amp at a relatively low cost and still get 93% efficiency out of the driver. Heres a light distribution chart for a highlight UV board on a XLG-200-h-AB driver @4amp in a 80cm x 80cm area. This is a...

Please can you explain how you calculated the wattage of the sun?

Wonder how many watts they are counting the sun as :wall:

Thats a much better fit and you should be good with it being dimmable.

Yeah just run them in parallel.

Just to note i work on 230v so if your on 120v please check that datasheet.

XLG drivers are all you need these days. Same efficiency as a hlg but half the price and more features then you could ever need. Pick the driver to suit your space and wire the strips in parallel. ( constant power so along as your in range its CC anyway) The XLG range have a current adjustment...

Do wonder how much he gets paid though. Was hortibloom for ages, now its the spida farmer, must have made him a better offer lol

Yes. Not sure of the technical reason but Its usually poor quality PCB manufacturing. I had it a lot with one certain company (not cutter)..

Just put the bolt through the end of your heatsink.

Whats wrong with a bolt and tslot nut?

Multimeters,clamp meters, Quantum sensors, lux meters, thermo couples. Spectrometer comes soon to. Just the tools of my trade really but all quality brands. Ive not got an integrating sphere in my office if that's what you're thinking :lol: My testing is based on price vs performance at...
