F15W BL365 UV Insect Zapper Replacement

Package includes two T8 F15W BL365 ultraviolet bulbs: each lamp body is 435mm long (approx. 18 inches), total length with pins is 450mm, and diameter is 25mm (1 inch). Also supplied with four spark starters. Compatible with all 30W insect trapping devices using standard T8 sockets. The BL365 designation indicates a phosphor blend engineered to emit strongest at 368nm — the ideal UV-A wavelength for stimulating flight orientation in common household pests including flies, mosquitoes, moths, and termites. Internal metal particles or gaseous metal generate UV-A light; a faint clicking sound when shaking is normal and expected. To maintain full functionality, replace the starter at the same time as the bulb — only where applicable (starterless units excluded).
