While on holiday in the USA I picked up a couple of small golf ball LED bulbs with ES fittings. These were to replace the two conventional light bulbs in my fridge freezer. They work well in this setting, and while a bit dimmer the light quality works well. While only on for a few minutes while the door was open, using conventional bulbs in a fridge bugged me, as it seemed they would introduce some heat into the fridge.
Recenetly i purchased a 60 watt equivalent LED bulb from my usual supplier, simplyLED, to see how far these have come. This one was advertised as a true 60 watt bulb replacement in terms of brightness and colour temperature.
So a good replacement bulb. It only consumes around 8 watts , so it uses half the power of a CFL and close to 10% of the power of the conventional bulb it replaces. Life expectancy is said to be 25 years. However cost was £15.
I think that costs will have to drop for these bulbs to show significant advantages over CFL bulbs which use only fractionally more power, but cost a few pounds. Some give better light quality , and wile they all improve after a few minutes, some are bright from turn on. CFL bulbs do seem to fail , and I doubt they still make the 25 year claims they once did.
For the present I'll be using CFL bulbs in these applications, but ill keep my eyes on LED light bulbs to see how they improve.
