Compact fluorescent lamps—CFLs for short—are used around the world to light up rooms, buildings and commercial spaces of all kinds. But, in order to make sure you’re providing enough voltage, you have to have the right ballasts. After all, without ballast, your CFL would rapidly draw too much from its electrical source. Dimming ballast is also available if you need to raise or lower the level of lighting at work or home. For additional ballasts, check out Zoro’s selection of HID ballasts and electronic ballasts.
