We are using surya CFL(14 watt) tube from 6 years. Now it’s cost is 110 Rs. It comes with 1 year warranty. You can get new one tube if it stop working in warranty. Mostly our all CFL works for approx. 1 year & 2 months . It is only Satisfactory tube. The best thing about this surya tube is that it glows well & consume 4 times less electricity then long 40 watt tube.
The long tube is difficult to handle. CFL’s are much much better than traditional yellow light bulb . That yellow light bulb consume 5 times more electricity than 14 watt CFL also the light og bulb is irritating not good for eyes. We are still unable to find better CFL tube than this in our budget. If anyone knows better CFL than this in our budget of RS. 150 .
