Halogen bulb ban

11 lamps here (2 of which are tubes).


£0.012 per hour for a 100w lamp is very cheap. At the rates I pay it would be £0.24 an hour (plus VAT).

Maybe the halogen bulbs used for cooking are a lot stronger than the ones used for lighting??

For example:
Replace a 100W incandescent with a 15W LED bulb that costs £1.45. You are saving 0.085kWh for every hour that it's turned on. If you pay 20p per kWh for your electricity, the bulb will pay for itself after 85 hours use. So definitely worthwhile for a bulb you use several hours a day; not so for a rarely-used one.

From what you say and tweetiepooh say, it's probably better to replace the bulbs most in use with LED lights until you have used up all of your stock. The bulbs that are replaced can be used in the other rooms when they fail.

50,000 hours lifespan ?
I think the lifespan of LED bulbs is exaggerated, thats 5.5 years (if on 24 x 7).
I've had a number need replacing already, after 2/3 years, and not in 24/7 use either.

This.

LED bulbs are particularly vulnerable to heat. I’ve had one fail after 12 months in an enclosed glass globe shade in the bathroom, and after a similarly short time in the kitchen close to the cooker. One of the ones in the room with our central heating stove failed after well under a year.

I don't buy fish on Ebay at all. Imagine what a cheap Chinese carp would be like by the time it got to you?!

I had a few GU10 LEDs a few years ago for the bathroom and kitchen that lasted about a year each if that.

However, subsequent GU10 bulbs I've bought have lasted several years and are still going strong, so perhaps the technology is getting better. All have been own-brand bought from DIY stores and supermarkets.

It's usually heat dissipation that's the problem. The LEDs are not happy being hot. If you have recessed lighting, you need bulbs with much better heat sinks than exposed bulbs.

We have expensive aluminium finned GU10s for recessed lights, cheapo plastic bodied ones for hanging light fixtures and all have lasted at least three years (even with kids who leave lights on all the time)
