CFL and lumens
I bought a few CFL yesterday, for our house and my parents in law's house.
For the living room we bought a 20w (100w equiv) 6500°K CFL. It's rated at 1090 lm (lumen) while the 2700°K one is rated at 1150.
For the bed room we bought a 15w (75w equiv) 6500°K CFL. It's rated at 760 lm while the 2700°K one is rated at 800.
For my bedside table we bought a 9w (45w equiv) 6500°K CFL. It's rated at 405 lm. It replaces a 5w (25w equiv) 2700°K, if I prefer the light quality of the newer one, I find it a little bit too strong for late evening and soon morning. I may swap with my wife's bedside table who is reading much more in bed then I do.
In my stock I found one with the lumen rate written on it : a 8w (35w equiv) 2700°K rated at 290 lm.
For my parents in law's chandelier we bought 6x5w (25w equiv) 2700°K rated at 180 lm.
