CMD4730840 Fly Killer Light Fitting 2 x 15W, Steel Case. This fly killer light fitting can be used free standing, wall mounted or suspended from the ceiling with the supplied chain. The fly killer and bug zapper should be fitted with shatterproof UVA tubes, but if shatterproof tubes are not required standard UVA tubes can also be fitted. This bug zapper is recommended for areas where food is served, prepared or eaten. It is recommended that the tubes are changed every year, as the UV content of the lamps reduces over time.
