SMD, LED, High Power LED - Advice needed

[timtheenchanter]

to add, I do not think you will find a 7-8W lamp that will fit a standard fitting, most, if not all, are longer than standard lamps.
5/6W is the max at a normal 50mm length. £12 is about right for these for decent lamps with a good life/cost/light ratio

So to sum up....
Assuming my fittings only take a standard bulb I'm looking at around a 5w max.
To get the best coverage angle I need SMD.
They need to be CE marked and I should expect to pay in the region of £12 (hopefully less for purchasing 20)
And as pure cool white or warm white... thats just personal preference.
