One of the bulbs did not work from the packaging. The one that worked was better than the American Bright Ligting MR16 bulb. Color still feels like a hospital with a pink hue rather than a gold one like halogen mr16.

I used this with my Insteon dimmers on a Tiella rail lighting system electronic transformer and they did great. You do need to be sure the total wattage of all the bulbs is high enough to keep the low voltage transformer from flickering this is true for halogen as well. I mixed LED with regular halogen bulbs in my system. I prefer the LED light quality of the spot. The halogens reflect light upward, making neat designs on my ceiling, and this does not happen with the LED.
