Questions on LED

Latest replacement for a failed GU10 kitchen bulb is an Eveready 370 lumen, daylight (6,500K) bulb with a 110 degree beam angle. £1.79 at LEDHUT, where they say it's 5W, but box says it's 4.2W. Either way, it fits in nicely with the other bulbs. Incidentally, box also says bulb life is 10 years/10,000 hours and >10,000 on/off cycles, so I won't need to replace them anytime soon!

I know I'm tempting fate, but I replaced 10 x 50watt GU10 halogens with LED Hut 4watt LEDs around eight years ago, and haven't had to replace any yet (I was getting through 2-3 halogens a year) The light spread from the wide angle LEDs is far better than that from the halogens so we have a more even light distribution

I personally don't like the stark white light from 6000k lamps, ours are about 3000k

To answer the OPs question about replacing them one at a time - why? Just change them all which should ensure that they all look the the same and you'll save more money in the long run.

Even if buying from more reputable suppliers, don't believe the stated life of 10 years, 10,000 hours or whatever huge number they quote. In my experience, they last nothing like that. Nearly all our house has LED bulbs and they usually last 2-3 years at best.

I've had a rather different experience, I moved into my house just over 4 years ago and the first thing I did was replace the lightbulbs, mostly from Poundland and a few from Home bargains. I've only had to replace 1 from 20odd.

I fitted 7 LEDs in the kitchen and 6 in the bathroom in Jan 2013. All reasonably expensive 7 watt ones.

The kitchen ones are still going strong but the bathroom ones - fitted in enclosures with only air vents at the top - failed one by one over the years. Only one of the originals is still working.

I now have more ventilated fittings in the bathroom and the LEDs (Philips Master type) look to be lasting.

In my experience ventilation is key - if the heat generated by the bulb can dissipate easily and quickly, then they will last. Put them in any fitting that restricts airflow (like 'can' type fittings where the bottom is sealed) and they won't last any longer than halogens.

Not sure what some people are doing with their LED bulbs but we have always bought ours from Ebay and have never had one fail yet.

The ones in the last house were all between 5 and 6 years old when we sold it.
