This is a McLux Black PR-T head for 3 volt bodies(Surefire E series compatible). This Turbo head looks awesome. Excellent condition. When used with a two stage switch it goes from normal to unbelievable. No visible marks on the head. A very bright and white beam. It will out throw the majority of 6 volt lights. You can amaze friends and bystanders. A slight amount of glow paint was added on the reflector around the LED. Not visible on the reflector in normal light. It creates a subtle glow at night after it has been used. A cool classic head. $120.00 including shipping in the US. PM me for questions. You get additional information from McLux's website.
