Review: Replaced shorter life halogens in Kitchenaid microwave - After only about a year of purchasing Kitchenaid microwave, both of the halogen work surface bulbs (on bottom of unit) burned out. Granted, we have them on almost always. I was surprised to find that they still used halogens. If a LED replacement is possible for ANY bulb, I will replace it. So that led me to finding these bulbs, and so far, so good. Better efficiency, and hopefully they will have expected longevity.
Review: Bright lights - Used these to replace halogens that were slowly burning out. I went with the 4K, which is a bluer light than the halogen 3K, to balance out the yellow of other halogens in my room. I find the balance pleasing. Dimming works great with my Lutron dimmer even at low levels: no flickering.

### ⭐⭐⭐⭐⭐ Excellent value
*by K***N on April 16, 2023*

It's been years that we wanted to replace our halogen bulb, with an LED that would fit our lamp, and doesn't produce all that heat. We're so glad to have found this product. It fits right in the socket and just works.
