12VDC battery powered Fluorescent, UVA, UVB & UVC Lamp Ballasts 4W to 18W with high efficiency.

Made entirely in Lincoln UK. No Imports


New Product ballast

Range 4W through to 18W designed specifically for actinic lamps as used in portable, field moth traps, incorporating filament pre-heat for low temperature starting. Will of course power any fluorescent lamp in the same power range.

The ballast has an integral Dusk-till-Dawn switch D2D enabling accurate switching at sundown and sunrise to conserve battery power, no relay used. Available as open PCB for personalised construction or can be supplied in a simple proprietary IP56 rated sealed enclosure complete with photocell and cable glands. Internally fused with a self re-setting fuse, which safely recovers from a reverse polarity power connection.
