There's something in common between LED retrofits and Soviet Union space exploration. You can not afford it unless you're the Government. Nice looking kW reduction, but a 32 year payback period. Which is...
NEVER IN FOREVER, FORGET IT.
County of Sacramento, CA commissioned an(expensive as usual) Government experiment project that ripped out 187 existing F32T8 systems with the following LED products and along with many complex dimming controls to go with them.
97 Philips EvoKits troffers
45 Gotham 41/06-4ARWD
18 ledgreenlight T8 retrofit external driver rewire type.
No labor charge, in-house labor used.
Project cost: $37,960. $23,000 of the above bill footed by socialism through other units of Government through ARRA and other Gubbermint programs. The remainder was probably the county's responsibility, which would've still come from tax payers.
They claim that the project reduced demand from 5.5kW to 2kW and estimate that the county will see $1,613 annual reduction on the power bill. On surface, it looks like its saving the public $1,613/yr, but in the larger picture, it's costing us a lot more to fund stuff like this.
If it's not financially sustainable, there's no savings. This would never work if it wasn't a large number people subsidizing a small quantity of projects or else the pyramid would collapse upon itself.
If you were to borrow $38K in the real world and you want to make $134.41 payments, this is what happens:
Principle: $37,960
APR.. if you could get it financed at 2%.
Monthly payment: $134.41. (the monthly power savings)
At this rate, you'll be paid off in 31.84 years. :lol::lol::lol:
$13,390 in interest.
$37,960 in principle.
$51,350 total.
