Helllo,
Just bought a new A++ Fridge/Freezer (Bosch) only 208 KW a year Average Great so far, only to find it has a 240 volt incandesant bulb inside 28 watts blazing away as my daughter takes an hour and a half to decide whether she wants a strawberry or cherry yogurt !!! Not to mention the heat that the fridge then has to compenasate for.
Can I change this for a Low energy bulb ?? any thoughts

Dont. They use more energy to start up than they do running. As the light will be on & off lots you will be better with a lower watt bulb.

Complete waste of time. Bulb is only on when the door is open, so will only use a trivial amount of energy. CFLs don't like cold, they are very dim at switch on and a bit more prone to failure from switching cycles. If you really want to do it you could fit an LED, but the effort involved is completely disproportionate.

Should have bought a samsung with a mini door in the main door to allow dairy products (milk etc) to be used frequently (or yoghurt etc)

Ok so its not really worth doing, never mind I will go out and creosote the greenhouse instead. Ps When the Motor isnt functioning and the door is shut, this new Bosch fridge of mine uses precisely 0 watts, yes thats right nothing, you would think it needed somthing to run the thermostat. And it only uses between 59-63 watts when cooling , beat that with your fancy mini door samsung then  |

justme. wether they have a start-up surge or not depends on model - some do some don't. It's not large though - still less than the incadescent. It's true that it probbaly won't work well (Slow start, dingy) unless you find one designed for cold conditions. An LED would be a good answer, e.g. an acriche, or one of the other new mains LEDs. Relatively expensive though, although I agree it is a bit gratuitous having an inefficient bulb in there even it doesn't get much use. The escaping 'cold' is probably rather more significant than the bulb wattage in practice.

Cheers for that. I too moan about the door held open but not for the light, for all the cold falling out the bottom.
They do do draw fridges now which are better, just like chest freezers are better than uprights.

My fridge has a low energy lamp in it, fitted as standard to it. its been working for years, doesnt need time to brighten up (jeez how much light do you need in a fridge anyway!  ) it lights almost instantly, certainly by the time the door is fully open anyway. So yes it can be done and is being done by some manufacturers and works very well. Andy. |

My fridge has a low energy lamp in it, fitted as standard to it. Yes, so do my fridge and freezer, 15w each. (jeez how much light do you need in a fridge anyway! Good point; easy solution take the bulb out - no energy used. A 15w bulb used in a fridge that is open for 15 minutes a day uses 1.4 units a year. If the fridge lasts 15 years that's 20 units or about £2 during its lifetime compared to about 3000 units overall for a really efficient fridge. What is the point of worrying about the light? Save more energy; get rid of the fridge and have a larder. |
