Energy Efficient Light Bulbs
21 Answers
I've bought some today F rated, they claim to use 90% less energy.
Now I know many people believe that you save very little in the way of money by keep turning lights off, that is debatable I think but in the long run it's got to make some difference in my view and one of the 3 reasons I bought them.
The second reason was because I like a white daylight bulb.
The 3rd reason is really my question. On the box it states, " Lasts up to 15 years" If the bulb gives up after 2 years, do I have a claim? I see it that I don't because it has lasted (UP) to 15 years, if my thoughts are correct is the claim of 15 years miss leading and not worth a dot because I would have to in some way prove a manufacturing fault that would almost be impossible to do. Any thoughts? By the way I have no such problem at the moment. :0)

They will claim it is 15years at so many hours per year, but in practice you are likely to use it it more hours than they say.
F rating does not sound good to me. The most efficient bulbs these days are LED ones, long lasting and using much less energy. They do pay for themselves. They come in warm and cool white.

One good thing about LED lamps (not bulbs!) is that they don't suffer if you keep turning them on and off, even quickly - unlike previous types (incandescent, CFL, halogen etc).
Plus, they do last for donkeys' years (highly scientific description) and they do use a fraction (something like an eighth?) of the power that a similarly- rated (light output in lumens) incandescent lamp uses.

LED bulbs are often claimed to last (up to) 15000 hours.
15years at 2.7 hours a day works out 15 x 365 x2.7 =14,782 hours so this is probably how they arrived at their figure. Whatever, LED Bulbs are the best purchase at the moment and will repay their initial cost, and other types are becoming less and less available.

These were 2x 40w and the cost is not that bad if they are going to last even only 2/3 years @£2.99 The old type bulbs that you can still get from the cheap shops are a complete waste of money they blow in no time at all mainly when one switches on and off. I just thought 15 years seemed a little over the top?
