I don’t like having anything in the grow tent that doesn’t have to be there

The QBs are 480w total, split in two fixtures 

I mount the drivers on a board outside:

Thanks my dude

Yeah, the silver doesn’t look too bad. My first effort at building my own QBs.

Ive refined the wiring, and the hanging arrangement. Black releases heat faster than any other colour, so the new ones are a little more effective.

These boys are quite heavy with those  massive sinks. A little over 7kgs each.

Haha ya you don’t wanna walk into them. I’m still looking for a heatsink with a thinner base, but these things are hard to find in this country.

yea they are, a friend of mine was looking for some in SA, but seems that there arent many forges in SA that are capable of high quality heatsinks in the dimensions we require.

and to manufacture them, …well.. you may as well import the most luxurious heatsinks from Italy instead because they will likely be cheaper

This build ends up costing me about the same as an HLG 550/650 kit, so not cheap. But I’ve got better cooling than those kits, so my boards should last a little longer. And when my boards are finished, I can just replace them.

Plus, there’s a lot of satisfaction making something yourself.

agreed, i have seen these first hand... they really are lovely - and the filter system you have, makes sure they stay clean.

 

love it
