LEDERA MR16 LED Bulbs Dimmable GU5.3 Light Bulb, AC/DC 12V, 5W (50W Equivalent), Warm White 3000K, 6-pack

Good soft white color--feels true to the 3000k advertised. No flicker. No delay in turning on or off (they're faster in fact than the halogens I replaced with these). My only negative is that they don't dim as much as my halogens did--maybe they go down about halfway vs. about 80% for the halogens. This makes these lights fine for the kitchen, where dimming isn't so important, but maybe less so for a bedroom. They also don't get warmer in color as they dim, a charming trait of halogens and other incandescent bulbs, but that's true of all LED bulbs, I think, and a trade-off for the energy saving, long life and low heat. They are also reasonably durable, as Amazon packed them with an 8 pack of D batteries, with no padding, so the batteries had knocked around and damaged the box the lights came in, but none of the lights were damaged.

Two have gone out of the 15 installed not sure if bulb or fixture

It appears they were not compatible with my Lutron dimmer. Unfortunately I had to return them.Never had a problem with Halogen 12v 20w lamps and Lutron dimmer. Likely not enough load using these LEDs.

Like all LED lights...good to great!
