Buying light bulbs has
always been tricky – clear or pearl, small or standard, screw or bayonet, spot,
candle or globe – and now it is even harder with low energy, halogen or LED to
consider, not to mention trying to gauge how many lumens are needed (watts being passé), so today
in Wilkinson’s even though I knew the shape and fitting needed I still stared at
the shelves for a good while doing a mental cost benefit analysis between the
halogen and the more expensive to buy but cheaper to run LED; for my bedside
lamp, on less than an hour a day, the payback was over six years, but what
really put me off was realising its projected life of 20,000 hours would see me
off with a couple of decades to spare.
