Review on Hyperikon GU10 LED Bulb Dimmable 6.5W=50W, 120V MR16 Light For Track Lighting, UL, Energy Star, Daylight White, 18 Pack by James Holker

I've been using Hyperikon GU 10 bulbs since the introduction of LED bulbs. Been very impressed and just purchased another dozen. Use them in 5 rooms and am quite satisfied. The come in a wide range of color temperatures, which was important to me. They dim as well as can be expected from LEDS, and better than others I've tried. However, don't expect dimming performance like an incandescent, although they do very well. However, you may need to buy different dimmers for any LED. I recommend an internet search for best dimmers for LEDs.
