UV light in AC duct?

Anyone installed one? One bulb or two? Looks pretty easy, but tell me how it went.
Thank you.

Don't waste your money they do not work in the air stream

I agree, I'd spend the money on either a better filter/filter system or a duct cleaning (if the ducts are in fact dirty).

They may not clean the air but they do keep mold from growing in the supply air plenum and outlet side of the evaporator coil.
The supply air plenum is where organic growth usually starts in the ducting system. (commonly due to return air leaks)

I was a skeptic (mainly because of what I read online) until I saw the results on houses that I service.
I have a single bulb 120VAC UV lamp for my supply air plenum.

I have also installed a mechanical filter and replaced my old flex ducting with round pipe ducts.
