I've had a few from different sources and found out the hard way to go for Warm White. The 16 Cool White bulbs had to be replaced! Used Fleabay as the prices are so competitive but went for uK seller so arrived quickly (go for 100% rating!). Recommend you get the highest power you can. My favourite bulb is 3 LED at 8 watts and has a good balance of pattern, colour and brightness and no failures yet.
I have had gu10's from various places the worst have been ebay cheapies, some lasted 2 days, others 6 months. Last few lots I have bought from toolstation and they have been really good, all still going strong. I use cool whites in the kitchen
Yes 3 or 4 as the top two images here: UK STOCK 4/ 6/ 8W LED SMD Spot Light Bulbs High Power GU10/MR16 Day/ Warm White | eBay
I bought 32 12W CRE LED with IP rated aluminium holders for our kitchen extension. Worked out at about £20 per unit all in. Came from some place in Saaaarfend. Only one failure so far.
