"Since LED and CFL lamps both have similar efficiencies you would need roughly the same wattage for both. "
I'm not sure, but I think LED efficiencies are getting better, in this case at least. The 50Weq CFLs that I removed from the kitchen, each used 11 watts, These 40Weq LED lamps are brighter and use 7.5 watts achieving 450 lumens @3000 K (using 32% less power?). 50Weq CFLs? Not so good.. Light Output (lumens) : 380 lm (15% less than the 40Weq LEDs?). Actual Color Temperature (K) : 2700 K 11-Watt (50W) Flood CFL Light Bulb (E)*-BPESL11R20/DM/ESM at The Home Depot And, LEDs are getting a little cheaper now.. But, with me it's not about price. For some reason, I'm attracted to efficient gizmos!! |
