Hot from me as quite a high light output.

and a lot safer than many of the no-name Chinese ones on eBay

Good price but even Poundland 5w leds works great!

I bought 16 of these for Kitchen/hall to replace existing 50w gu10 halogens a few months ago. Work well but they're brighter than the halogens were. We've got used to them now but were in 2 minds to take them back. Please bear this is mind if buying.

Are these actually any better than these also at Screwfix that work at £1.40 per bulb?

Hot from me for a reputable make, dimmable LED spotlight.

I wasn't aware of that, but that's not something that I need. Is it worth the extra 60p per bulb for the Philips as opposed to the LAP?

If you dont need dimmable then LAP brand is fine - I've got these in my bathroom for some time and had no problems.
