LED lights Best MR16 Halogen Alternative These LED lights are the best MR16 halogen alternative I've ever tried including pricier Philips and Osram. They are heavy and seem to have a higher build quality. I got both 3000K and 2700K versions in 600 degrees, and 2700K is closer to halogen color. These 3000K bulbs have a tad whiter light than my halogens, and I preferred the 2700K for kitchen light. The only negative point is that these bulbs are about 1/8" longer than standard MR16 LED Spot Reflector Lamps , so they didn't fit in my older track light fixture that has a glass reflector. Also, the first time that I tried them, they started to blink/flash rapidly on my Lutron Caseta dimmer. Then I learned how to adjust the high level trim on the dimmer switch, and when I lowered the high level trim preset, they just stopped flashing and worked perfectly. You can find more info about how to adjust high and low level trims in Lutron user manual.
