    I'm constructing a DIY UV air purifier that uses one UVC 40W lamp. So far, I’ve purchase two UVC lamps and two ballasts but have failed to get a lamp and ballast pair that works :-(

    Purely UV - UVC Germicidal Lamp PUVP0040

    Fulham WH33-120-L WorkHorse 33 Ballast

    The KTEB ballast only lights the very ends of the Purely UV lamp and only makes the heating elements on the UVC lamp glow.

    The WorkHorse 33 dimly lights the length of the Purely UV and does nothing on the UVC GPH843T5L lamp – even though it should be able to instant start the GPH843T5L per my understanding of the flyer below.

    Ugh. What a waste of money.

    I sure hope someone can help me?! Can I just go to Lowes and buy a 2x50W fluorescent ballast and wire it to start one of the lamps?

    Thank you.

    Tha fios agaibh,

    I’m a bit confused because the Fulham document lists a WorkHorse 33 with the UVC GPH843T5L lamp – page 14. Also, I recently bought a professional 180W UVC lamp that was started with a WorkHorse 7 ballast. In other discussions I found on the subject, it seemed like the two were interchangeable? What’s the difference between a CFL and UVC ballast?

    I didn’t mention it but I also tried a LSE Lighting 40W Ultraviolet Germicidal UV Fluorescent Ballast. It didn't work.

    Yikes, that doesn't sound good.
    I am not familiar with uv lights, but i
    believe your dealing with an induction light that does not have any electrodes inside the lamp. It's a different animal than your standard fluorescent lamp.
    Best I can say, is to make sure the ballast specifically lists the type of lamp your using (and the number of lamps used).
    If you miss match lamps and ballasts, you risk burning out one or the other.

    I read the same thing from the flyer. I would suggest you contact the ballast manufacturer and see if they can help you.
