4-Pin Base Bulbs

Linear lamps with a 4-pin base are most often used in ultraviolet germicidal applications. Because equipment using these 4-pin base UVC bulbs are often installed in HVAC systems or water purifiers, maintenance is easier with a 4-pin base lamp, as the 4-pin socket can be disconnected so the bulb can slide out. These bulbs come in a wide variety of lengths, outputs, wattages, and ozone producing properties.
