Re: Compact Fluorescent Light Bulbs – A Tale From Dust to Dust

Hi Frank,

I haven't seen anything like this for LED's. The analysis that I did above has nothing to do with cost though, just the energy requirement. I think LED's are quite a bit more expensive than CFL's right now and much more expensive than incandescents and for them to be even comparable in terms of cost (as in $ not kWh), then you'd probably have to be using them 24hrs/day, 7 days a week. I know that LEDs are cost effective when they are being used in tunnels since tunnels need constant lighting.
