Streamlight ProTac Rail Mount HL-X Weapon Light 1000 Lumens – 88066

The Streamlight ProTac Rail Mount HL-X (SKU 88066) is a long-throwing rail-mounted rifle light producing 1000 lumens output and 50,000 candela peak beam intensity for a 447 metre beam, with a 60 lumen low giving 3,100 candela and 111 metres. That candela figure is what makes it a genuine lamping light rather than a close-range flood.

It ships complete with both a remote pressure switch and a push-button tail cap, and TEN-TAP programming sets the mode order to high/strobe, high only, or low/high. It is dual fuel, running either one SL-B26 rechargeable pack or two CR123A lithium cells; this 88066 kit is supplied with two CR123A cells and does not include an SL-B26 or charging cord. Anodised aluminium body with a tempered-glass lens, rated IP67 with the push-button fitted.

How It Compares

The HL-X is the long-range option in the ProTac rail range — roughly double the throw of the Streamlight ProTac Rail Mount 2 rifle weapon light and far beyond the Streamlight ProTac Rail Mount 1 rifle weapon light. For the same beam with a rechargeable pack and redundant switching see the Streamlight ProTac Rail Mount HL-X Pro USB rifle weapon light.
