CFL lamps

Falling prey to the hype around CFL lamps and their energy efficient, earth friendly ways, I have been using them for a while around my house. But my overall experience with them has not been very good. They dont last as long as promised; in many cases their life is less than the incandescent predecessors that they replaced. I am sure it reduced my electricity bill - but on a cost benefit analysis, I am not sure it passes the test. With a cost anywhere between 10-15 times ordinary bulbs, their life is pretty low.


Any similar experiences? Is it due to the thousand power cuts we have in a day?

That's strange. My personal experience with CFLs has been very good in terms of life. The only problem I've faced has been when the inductor at the base was wonky once and it used to make a persistent buzzing.

I used the Havells CFLs - not too expensive and very long lived.

When good quality CFLs are available for cheap prices, energy consumption would come down a lot.

Now availability is an issue.
What would help? Subsidized CFLs?
How else can CFLs be made popular in a price conscious market.

Life of CFL depends on continuous ON it seems, Philips give good life in my office because its always ON, but same when I bought for home it lost life within 1 yr, fortunately warranty period so got replaced, I think there are spurious quality available, check for made in vietnam, China etc all brands they have such Vietnam is not at all good. My experience is also same within 1 yr all CFL failed havells, but one in puja room is ok which is alwsys on, so blame it on frequent swith off

My experience with CFLs has been very good . In the earlier (soulquest) office we had installed CFL lights . It's been more than 3 years now and they still work fine . In the current office almost all the lights are CFL. Our energy bill is quite moderate for an office . Besides the fact that we switch off lights and devices when not in use I am sure the choice of CFL contributes to the cost savings as well.

Life of CFL depends on the way you use it. If you use it in the bathroom or store room where you are going to switch it off and on frequently, its life will be short. Also voltage fluctuations affect its life. Even a faulty switch can cause the CFL to go bad. There are from my previous experiences.
But I heard that the latest cfls are better and lasts long.

Thanks for the inputs guys. Bangalore surely has a voltage/power situation - perhaps thats part of the reason my experience with CFLs is not upto the mark! Jinxed :) I dont know...
