There are many valid and good comments here. CFL’s in Asia, there is no disposal for it and most ending up in local landfills. And CFL’s and tubes are widely spread here. Said to see. And i researched on mercury, amazing how many people in China died because of poor manufactoring process and handling.

LED’s have done a tremendous progress in the last two years. A CFL and tube has about 50-60 lumen/Watt. LED in these days already at around 100 lumen/Watt. LED’s from my manufactorer come with 2 years warranty (you wont have any warranty on Halogen, CFL or incandescent). They save about 40-90% on electricity and about 6 times replacement (lights plus labour) compared to CFL and tubes. And yes, they are more expensive, but putting in above benefits into dollars, the LED will usually have a return of investment within 1-2 years. For Halgen and incandescent its usually below 1 year. I havent found any stock how gives this return !!! Surely they will get cheaper over time, but how long do we want to wait ? I could have still waited on my to computer to get cheaper, I would be sitting and waiting for the last 20 years. Everytime is the right time. So we should make a start now.
