### ⭐⭐⭐⭐⭐ Energy efficient, reasonably priced
*by K***. on September 2, 2022*

I needed a replacement bulb. I am happy with the Sylvania brand since it has been around for some time. The light is bright, energy efficient and should last for a long time. My only complaint....I wasn't very happy with the packaging. The box it was shipped in was twice the size of the light and there was no padding of any kind. I was surprised the light wasn't broken.
