These days we all know that the old fashioned incandescent light bulbs are not a good idea, because they're inefficient.
However energy saving flourescent bulbs aren't exactly perfect - given that they contain mercury (which is a serious issue when it comes to disposal, and although they last longer than conventional light bulbs, they don't last forever and do need to be disposed of at some point). The quality of the light emitted by these light bulbs is thought to also be behind some health problems so again not ideal. Unfortunately though we're being pushed into buying fluorescent bulbs to save energy. Many countries are phasing out the use and sale of incandescent light bulbs.
So I've always been interested in trying out the LED lights (Light Emitting Diodes). These don't contain mercury and are more efficient and longer lasting than incandescent light-bulbs. The main problems with these so far have been a) high prices, b) incompatibility with conventional light fittings.Both these problems are likely to be addressed in the near future.
So I was delighted when digital media agency Spread It Fast sent me a couple of LED bulbs to review. As I noted above, LED bulbs aren't always compatible with conventional light fittings and I was disappointed that of the range of LED bulbs available, only one was compatible with any of the light fittings in our flat and most of our light fittings can't take any of the bulbs I was offered.
First impressions though are very positive. The bulb is expected to last for 15 years and is guaranteed for two.
So if you're looking for new light bulbs, I would definitely recommend looking at LEDs at least to start with, They are coming down in price and there seems to be a greater variety of designs all the time, so that hopefully soon it will become easier to find an LED bulb for any light fitting.
