Without doubt we believe this is the best gunlight available today. Made with an aluminium body, aluminium reflector and Borosilicate glass and fitting with a 50 watt Xenon bulb, it is rated at 1 million candle power. A 100 watt bulb can be purchased as an optional extra to give in the order of 1.5 million candle power output. It has a 25mm barrel fitting which is supplied with rubber reducer so it will go on smaller barrels. The stock switch and coil lead with cigar plug fitting can be plugged into a car cigar socket or the 12v 7ah canvas power pack which comes complete with shoulder strap and mains charger
