Review: Works - Replaced my broken ballast that came with my UV filter. Makes a beep and has a light on to let you know when it is plugged in.
Review: Replaced express water ballast - I used this to replace my Express Water ballast that failed since Express Water will not sell just the ballast. It works great and my under sink UV is working again. We'll see how long it lasts.

### ⭐⭐⭐⭐⭐ Works

### ⭐⭐⭐⭐⭐ Replaced express water ballast
*by M***M on November 29, 2023*

I used this to replace my Express Water ballast that failed since Express Water will not sell just the ballast. It works great and my under sink UV is working again. We'll see how long it lasts.

### ⭐⭐⭐⭐ Works
*by J***R on August 2, 2019*

It works. Even with old UV bulb. Must be plugged in in the correct sequence for bulb to light (pay attention to small, white sheet of paper in package). LEDs are nice feature. Only issue is that the plastic cap on the end of the wire means that the wire can’t be threaded through a small hole into an enclosure.
