I am not sure I agree with CCFL putting out more lumens than LED, my house is 100% LED from downlights to the regular globe replacements, personally I prefer the output (look and instant 100%) to CCFL but either way the lumens IME are slightly higher per watt with LED and figures I can find seem to back that up...
| Incandescent Watts | CFL Watts | LED Watts | Lumens (Brightness) |
| 40 | 8 - 12 | 6 - 9 | 400 - 500 |
| 60 | 13 - 18 | 8 - 12.5 | 650 - 900 |
| 75 - 100 | 18 - 22 | 13+ | 1100 - 1750 |
| 100 | 23 -30 | 16 - 20 | 1800+ |
| 150 | 30 - 55 | 25 - 28 | 2780 |
http://eartheasy.com/live_energyeff_lighting.htmYou should have seen the original lighting we had in the lounge when we moved in, they had these huge downlights, each one was one of those outdoor 200W flood lights.. Hilarious as lounge had 4 of them and no dimmer, so 800W, replaced with 6 x 9.5W LEDs on dimmers, plenty bright enough (before it was a joke) and drastic power saving...
As to solar we were lucky to get it in time for the higher rate so we make more during the day (when no one home) than we pay for at night, at 8c I don't know if I would have bothered though, takes much longer to pay it off..
