ASDA 15W 1521 lumen LED bulb dimmable bayonet or E27 screw fitting - £8.33

This high spec LED bulb does not yet appear in ASDA's website (now it does), but I've just bought one.
15 Watts is a very high rating for LED bulb. The price is good and 1521 lumens is the claim (equivalent to 100 watts tungsten). Even better is that it is supposed to be dimmable and claims 25,000 hours life.
I will test it shortly. But from the specification it's the very latest technology and the price whist still expensive is the lowest I've seen.
Update 22nd Oct. Seems to work very well. Quite a warm light. Power from mains is 17.2 watts dropping to 16.1 watts when heated up. Dimming is smooth and quiet if you use a good quality dimmer such as varilight Vpro set to trailing edge mode ( for good technical reasons, trailing edge is better than leading edge. Leading edge is the common low cost low performance 'dimmer switch')
It does get hot. Used without a dimmer the case reached 86°C in a 24°C room ambient.
Takes about 4 seconds to start up with the dimmer set to minimum, very fast start up otherwise.

That's bright! The helical fluorescents like Philips Tornado only go up to 1300lumen at 23W.

Good lumens output, I've been using 10 Watt daylight with 1200 Lumens (they're bright)from CPC for £3.40ish though if you need light OP is hard to beat. Shame it's warm white though.

Voted hot. Seems a good price for that number of lumens,

I bought this for a tenner a week ago. It's very bright indeed but it is fairly noisy for a light bulb. Gives you a buzzing noise but I'm used to it now and for households who usually have a bit of background noise you can't really go wrong for that price.

just bought one today excellent bulb and brightness thanks. Compared to my 23w CFLs which are rated at 100w equivalent I would say its pretty spot on or maybe slightly brighter than the CFL which is only around 5 months old. Lets see how long it lasts thats the test.

Replace the light fitting and the noise will disappear. Old style bulbs caused heat that damaged the light fitting. I replaced these where noise occurred and all I could hear was "silence".
