Hi GG, thanks for getting back to me. I've taken your advice and changed the pot. Its early days but it seems to be stable. Desperately hoping it's not a driver problem, If it comes back that's where I'll look next. Cheers.

Hi, Thanks for a quick response. I'm using a potentiometer, a cheap one from AliExpress. It's 100k along with a resistor but I haven't been able to check the pots. precise value.

Happy New Year to everybody and thanks for taking the time to read this and hopefully give advice. Setup = HLG 480H 48B 20x F-Series LT-F564B / 2 foot Strips.

Thanks for your maths Crazyphil. Hi Warbar, I think, I have to apologize for what I think to be a huge mistake from me yesterday. I have good news for you Your plate should take 5 W Heat out .(Al thermal conduct. = 185 W.m².c, Surf. of you plate =0.0276 m²(incl. sides)=5.11W) But this is for every s...

I looked into the heatsinks and in this part of the world they cost a fortune. The equivalent of $550-$600.

I then found this site and my eyes were opened as to what could be achieved. I found a 4x4 build by LG and expanded it knowing that at tim...

I'm an experienced HPS grower forced to downsize from a 2.4 x 2.4m grow space to either a 1.5 x 1.5m or 2 x 2m grow tent depending on strain and yield. So what i'm looking for is a very high performing build to try and compensate for lost floor space. Will this work? My idea is to run 40 Samsung LT-...

Experienced HPS grower still learning. Forced to downsize but hoping to achieve similar if not better results using LEDS. Looking forward to learning more and a satisfying build.
