This document provides information about blacklight lamps manufactured by Havells. It discusses how blacklight lamps attract insects using UV-A radiation and their applications in insect trapping and nail curing. The document introduces Havells' new BL368 blacklight lamp, which features a narrower spectral peak at 368nm that makes it more effective at attracting insects than the previous BL350 model. It also maintains 80% of its UV-A output after 5000 hours of use.
