Replacement for Uvp CAL 91778 - 4W, Bipin Base

This 4-watt T5 blacklight tube replaces the Uvp CAL 91778. It features a G5 miniature bi-pin base and emits UV-A radiation in the 350-370 nanometer range - wavelengths nearly invisible to humans but highly attractive to insects.

The UV-A spectrum emitted by this tube is highly attractive to flying pests - mosquitoes, gnats, flies, and moths navigate toward it instinctively. While humans barely perceive the faint purple glow, insects see a beacon they cannot resist.
