A colleague received a sample 5W LED GU10 lamp for trial from a wholesaler.
It's now fitted in his basement toilet and throws out more than enough light. I was quite impressed to be honest. No cheap though, around £17 IIRC.
Will try and find out the manufacturer.
Be interested to know as £17 is reasonable for good light output, depending on lifetime.
Ones I have been looking at are 30,000 to 80,000
