The SL4 eLED is a secondary light with the reach of a bright beam that is still small enough to take anywhere. The eLED will remain consistently bright for over 50,000 hours! 5.5 watt high pressure xenon lamp and precision machined alum reflector gives a bright narrow beam for sighting distant objects. Works well as a photo spotting light. Thumb or index finger activated rotary switch for one handed operation. Non-conductive ABS and polycarb plastic construction. Lanyard included. Proudly made in the USA.
