Power saving tips and ways to save money!?

[reefwars]

But those costs wont bridge the 4+ years difference.

the saying is leds cost less per month then mh do, not that youll recover the cost of a fixture in a year or less.......we know you wont save that much or there wouldnt be mh's still around.
you proved it yourself , leds do save money....how much money they save probably doesnt add up to a light fixtures cost when upgrading but the claims are true , they cost less to run then mh.

now the next argument is do leds do what mh's do lol?
