No LED requires an exact power level. The whites you linked are listed as 6.5 - 56 watts and the white/red/blue are 2.2 - 25.7I'll take your word for it man! I don't intend on playing around with deadly electricity.
I'm now looking for two drivers to run 4 strips in series each. I found Meanwell's HLG-80H-C700A that I think could run the 4.
But I am wondering, is it correct to only be looking at HLG drivers for these LEDs or are other drivers also going to work good? Getting a 70W one would be ideal, since the 4 strips require exactly that much.
