But how many volt-amps are the 100+ lumen per watt lights using?
Cheap power supply inefficiency is a big part of the problem.
I bought some Sylvania "250 watt replacements" about 4 years ago back when they were pushing $44 each after sales tax.
Then I moved, took the old LEDs with me and installed them at my new place, then went back and bought more of the exact same led floods when I installed more lights, now $33 each.
As far as I can tell the new and old ones don't look any different from each other.
But the old ones were also on a timer, so they were rarely ever on more than 30min. So they may still be like new.
