Where are you getting best price on boards? Amazon/ aliababa / eBay? Shipping costs suck right now from overseas. I have 4 -240watt drivers looking to make some rock hard bud thanks
Amazon will sometimes have listings for the basic 288chip boards once and a while. I've seen listings for heatsinks too. I think if you're just getting boards and heatsinks, doing a bulk board order on alibaba might be the cheapest. I was shopping around not too long ago and could get 4 board for like $160 canadian all in from overseas. No heatsinks though.
If you are shopping from america i would keep my eyes on deals that comes here and there. Many have free shipping in the us. As an european alibaba has worked ok for me. There is shipping Costs and time though
Horticulture Lighting Group have a sale on some of their boards: https://horticulturelightinggroup.com/collections/all/products/qb288-v2-rspec-quantum-board
Aye yeah not exactly what you had in mind, but that's what they make dimmers for. Plus you can always cut that heatsink in half and have two lights, win win. I ALMOST grabbed a used kingbrite QB online for like $150 CAD, I Should have.
yeah I was looking to make a couple 400+ watt lights but this will be added into the mix. It’s actually the smallest low watt light I use. Lol
