### ⭐⭐⭐⭐⭐ Bright way to save electricity
*by B***B on July 19, 2024*

The instructions are very easy to follow and took only a short time to install. It emits even nicer light than the fluorescent bulbs this replaced. Just one caveat, if you're not skilled or comfortable installing electric fixtures, this may not be for you. This is my 5th retrofit using either 2 or 4 magnetized LED strips, so I am sold on the energy savings and improved lighting these LED strips provide.

### ⭐⭐⭐⭐⭐ Bright and went together well
*by A***S on October 29, 2020*

I would purchase this again the next time a ballast fails in a fluorescent. I think it is a better option to replacing ballast. It's not without minor annoyances, though. It takes about 2 seconds to turn on, and it has a very faint hum. Otherwise, assuming it lasts close to the advertised 50,000 hours, I am very happy with it. One other thing to note is that the instructions are a bit underwhelming. I purchased the "dimming" model. I am used to the dimming occurring at the light switch via a slider module. In this case, the dimming has a separate pair of wires that I have no idea what to do with. I capped them and the light seem to work fine without using them.
