$22 per strip is still below $1 per watt. Pretty hard to get lower than that.
Higher powered cobs or strips require bigger sinks which ratchet up overall cost faster than anything else. Long strips and heatsinks shipping adds to costs as well
If you buy 10 plus the price is at under 18 per strip
i understand.
when i built my cxb3590 lights i did a ton of research. my first four were a real pain using heatsink usa sinks. i had to buy a drill press etc.
the next 12 i built using the pin heatsinks, were easier, way lighter, and cheaper. the costs these days are better but even back than arrow usually beat digikey by a wide margin. that was my point.
these f series strips are a great deal either way and i appreciate the help since i didn't have the time to do all the research on what is the best bang for the buck now.
i already ordered everything to build my first three lights to see how i like them. I went the cheap route with the single row from arrow in 1120 mm.
my reconfigured 8 cob lights running at 700 ma should cut my electric by a nice margin and if i can reuse some or all of the old drivers without spending alot building decent lights it will be a win all the way around.
i spent about 250 to make my first three lights which is about 600 watts!
