    i usually build my lights for customers with the same u-channels but running them at 1050mA, that would have brought down the cost a lot too, just for my personal projects i like to spend a bit more, as the strips are still dirt cheap and still at around 2,6µmol/J

    Samsung Q-Series heatsink

    sure about the eu warehouse? every order so far i or a friend did via digikey came from the states (5 orders so far), good thing is customs and shipping is already priced in, you only need to pay VAT on your orders so i don't really mind where they are shipping from, it's usually faster than...
