Can you please post your purchasing source, I bet a lot of people would really like to partake.
That was an exceptionally good deal, but normally I'm not likely to pay more than 60 pence per bulb, and for better bulbs. Those bulbs, I'm still testing, but they do come with a 1 year guarantee, so at the moment I'm a little unsure as to whether to give the source, since I don't know how long they will last. I will tell you that the bulbs are on eBay, and many are of Chinese origin. I believe you will need adapters so that they will work in your fittings, but these only have to be bought once, so that's not so bad.

IMO buying LEDs from generic Chinese manufacturers is a recipe for disappointment. There's no quality control in Chinese manufacturing. Buy a name brand. Then if it fails prematurely, you can get a replacement.

Also they are too intensely directional.

no, no, no...foot-candles is where it's at daddy-o!

Who do you think makes the LEDS for the name brands, the Americans?

There is plenty of QA in manufacturing in China, you just have to pay for it. If all you demand is cheap, cheap you'll get.

Yes. Americans in North Carolina to be specific. Cree still manufactures a large portion of their LED bulbs in North Carolina and the R&D is done in California. A large portion of their international sales are produced in HK.

I actually like the directionality of LEDs. I've been picking bulbs that are less likely to put light where I don't want it. As an example; I've put bulbs in my outside fittings, that don't spew too much light up into the sky, or even down on the ground so much, but out across my garden, where I want it to go.

Chinese manufacturing is OK. Chinese QC is an oxymoron. I will continue to buy from western companies because they understand my need for quality.
