Integral Dichroic Glass 4.4 Watt GU10 LED Bulb.
I was searching the Internet to replace my 50W GU10 spotlights. I had read reviews on Amazon and the common thread was that numerous replacement LED's kept on blowing and had to be replaced. Luckily after searching some more, I found your explanation on the differences between LED's and GU10 spotlights. I then bought the above bulbs and received them the next day. I have to say they are fantastic - they look great (you can't see tons of yellow led things!), are obviously well made and are a perfect replacement for my 50W lights. Anybody reading, I would just say, beware of cheap replacement bulbs - you get what you pay for.
Many thanks for a great service.
