/diy/ - Do It Yourself

>>1726960
I'm a squatter from >>>/out/ looking to DIY a grow light and just wanted to get some confirmation on things, I've never messed with this stuff before

So Samsung has there horticulture linears and I'm looking to use 2 of them, they are 2 feet long and consume ~51w each at the typical drive current of 1200ma, I know I can't get away without a heatsink and trying to find a premade one with the right dimensions is proving to be a nightmare, I'm wondering if I can just get a raw aluminum plate cut and just use that and if so what thickness would it might need to be?
Or could I even go a step further and get some aluminum angle bars or something from home depot or similar?

Also would an HLG-120H-48A be fine for driving 2 of them in parallel? That would give 1250ma to each strip and I wouldn't think the extra 50ma would hurt anything
