more amps less cobs vs less amps more cobs.

I personally run my cxa3070's at 2.5 amps each. I don't see the reason to be running my lights soft. the only advantage being what? life span.. so instead of 7 or 8 years I might get 4 or 5?. woopty do. if i get 5 years out of one chip or driver ill be happy.

besides if you run em a little harder they penetrate that plant more. i think the over all results of the plant are worth running em hard.
the 3 to 5% loss that you get in your power bill is negotiable I think. when you calculate driver, heat sync, and chip cost vs running cost.. especially if power is free or near free ( solar panels/wind)

besides 4 or 5 years from now when my lights die.. it'll probably be cheaper to buy parts when i need them

your missing efficiency and even coverage. both are huge factors.

In fact the lifespan is probably the lowest priority, since in a few years there will be better lighting technology.

sorry man but you really missed the boat.

is 2% such a huge factor in real life? even coverage? I have a set up where one light is on each plant.. maybe if your dumb and put all your lights in one basket then i could see coverage being an issue. or if your trying to light an extremely large grow area.. do you even notice the difference on your power bill running 8 lamps at 25 Ws or 2 at 100Ws.. like what 1 or 2 bucks a month .. vs the amount you paid for all those chips heat sinks and drivers?

dude the efficiency your missing is not 2%. time for you to do some research and answer your own question
