The L-A7W-UV is a 7-Watt UV LED light bulb that puts out 395nm ultraviolet light. It is powered by 110V or 220V AC power and uses a standard screw-in E27 base socket. The CNC machined aluminum body helps dissipate the heat and the 45 degree focus lens helps focus and intensify the ultra-violet light coming out of the bulbs. The L-A7W-UV consumes 7-watts of power and puts out the most UV light from a single LED bulb.
