Invested in the so called 15,000 hour LED domestic BC light bulb, that has gone phut in what appears to be a very short lifetime - so much for the 85% energy saving and their "long life and high efficiency make them a real money saver, allowing for a combined possible saving of up to £240 a year!"
At £5 a pop, I wouldn't call that cheap, by any means.
I have an Energy Saving Fluorescent Bulbs. 11W in a floor standard lamp that I set up for my disabled wife, and that has been running day and night for well over a year now - THAT is economy, not these new shit LED bulbs.
