Halogen spotlights should go

I replaced my halogen spotlights as soon as we moved in and everyone else should too.

In a row of four, one halogen bulb consumed 50W, while an LED one with a similar lumen rating (amount of light emitted) is using 4.5W each. That's a staggering 200W to 18W switch without any less light at a cost of around £15 ordered online.

Hi dain. I never realised the difference is so huge. But given the high price of LED, how long do you think it will take before you start making savings?

Hey, Laser: mine are 350 Lumens and I actually even find them a bit too bright. Halan: they were less than £4 each, so with one kWh at around 15 pence you save the full price of the bulb after around 590 hours of use (1kW / 45W = 22.2; 400p / 15p = 26.6; 26.6 * 22.2 = 590.52h). So if you have the lights on 3 hours a day on average, it's less than 200 days or a bit more than half a year to totally recover the investment, which is not even mentioning that LEDs have practically infinite lifespan compared to halogen bulbs which tend to burn off very quickly. I got them from LED hut: http://www.ledhut.co.uk/spot-lights/gu10-led-bulbs.html, do not pay full price though, I got them at a 30% discount plus 20% cashback via Quidco last year.

You get what you pay for. We have cheap (Eton brand) LED bulbs that have replaced almost all of the halogen spotlights. They are bright white and blow quite regularly. I think they are over-driven and/or have inadequate heat-sinking. I bought 2 better quality Phillips LED bulbs (about £15 for the pair a few years ago) and they are much more reliable. Still going strong and the colour is warmer. It's very difficult to tell them apart from regular incandescent bulbs.

js: LED hut offers 5 year extended warranty for free, so even though I haven't heard of LumiLife brand before that sounded promising: https://www.ledhut.co.uk/warranty I'm not saying anyone should absolutely order from them, but I guess it's a good starting point for a search what's a reasonable deal on the market. It's a good point though that even the warmest version I got is a bit too blueish for my taste, so I ended up ordering some yellow foil designed for car headlights to not have too much cortisol in the evening...

I found a website that gave a nice comparison of cost of led vs halogen. Halogens apparently cost about 700% more to run per year! I created another thread so I can post a picture, as I couldn't do so in a comment: https://energyuse.eu/discussions/55/
