Budwizer 162 Posted March 14 Share Posted March 14 These are my DIY QB lights I can run them full power with no issues. Quite expensive to build, but I like the reliability of passive cooling. 5 Quote Link to post Share on other sites

Budwizer 162 Posted March 14 Author Share Posted March 14 Can’t find the correct heatsink on RS now, but this is the closest: https://za.rs-online.com/web/p/heatsinks/4907056/ The ones I used are 300 x 200 x 40 1 Quote Link to post Share on other sites
GGG 760 Posted March 14 Share Posted March 14 Cool Thx man, will have a look Sent from my F5321 using Tapatalk Quote Link to post Share on other sites
Dookie69 116 Posted March 14 Share Posted March 14 Very very neat. How much power does it draw? Is the driver separate or is in integrated on the light itself? Sent from my iPhone using Tapatalk Quote Link to post Share on other sites
Budwizer 162 Posted March 14 Author Share Posted March 14 (edited) 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: Edited March 14 by Budwizer Added wattage detail 3 Quote Link to post Share on other sites
PsyCLown 3,867 Posted March 15 Share Posted March 15 Very neat build, love the black! Far better than the plain silver. 2 Quote Link to post Share on other sites
Budwizer 162 Posted March 15 Author Share Posted March 15 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. 1 Quote Link to post Share on other sites

Budwizer 162 Posted March 15 Author Share Posted March 15 Just now, CreX said: beautiful man!! shit at 7 kilos you best not bang your noggin haha!! 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. 1 Quote Link to post Share on other sites
CreX 3,608 Posted March 15 Share Posted March 15 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 1 Quote Link to post Share on other sites
Budwizer 162 Posted March 15 Author Share Posted March 15 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. 1 Quote Link to post Share on other sites
CreX 3,608 Posted March 15 Share Posted March 15 agreed, i have seen these first hand... they really are lovely - and the filter system you have, makes sure they stay clean. love it 1 Quote Link to post Share on other sites
