40-W-UVC-Keimlicht-Elektronikballast mit Vorheizstart

This transformer is perfect for a 40 W unit it's, drip proof and easy to install. We will be stocking several of these to keep on hand for our clients.

Excellent service, fine price, fast delivery

This is the 3rd ballast I've purchased in last 2 years. First one lasted two months, then melted housing, presumably from over heat. Second one lasted about a year, then green light (on-ok) went to blinking red.
I use this with a UV bulb in a 1000 gal fish pond. It runs with the water pump/filter which is about 8 hours per day.
When it runs, it does a great job of UV cleaning the water.
UV bulb works great,
