Is there any sites that ship supplies from canada..interested in doing a qb board or cob build but would like to properly price it and don't want to pay duties...preferably sites people have dealt with to get they're supplies
www.horticulturelightinggroup.ca for qb products in canada.
Digikey.ca is good for cobs and samsung and bridgelux strips.
I use mousser for drivers. They take care of duties for you.
If using strips just use aluminum u channel for an easy cheap heatsink.
For cobs it is hard to find pin fin heatsinks in Canada. You can use a cpu heatsink cooler as an alternative.
When I made my order from RapidLED for my cobs the duties was like 27$ on a 350$ us order with shipping being 60$ so it was around 100 bucks cdn for shipping and duties combined.
