It is rated IP67 — one metre for thirty minutes — with the tail switch in place, and mounts directly to MIL-STD-1913 Picatinny with an M-LOK mount also supplied. A push-button tail switch handles activation, and TEN-TAP programming sets the order of the modes.\u003c\/p\u003e\n\u003cp\u003eOn the SL-B9 pack the light gives 850 lumens, 30,000 candela and a 346 metre beam for half an hour, or 100 lumens, 3,400 candela and 117 metres for four and a half hours on low; strobe runs an hour and a quarter. Dropping in a CR123A lithium cell gives 500 lumens, 18,000 candela and 268 metres for one and three quarter hours, with the same 100 lumen low lasting six and a half. Worth planning around: the headline 850 lumens is the rechargeable figure and it is a thirty minute figure, so carry a spare cell for a long night.\u003c\/p\u003e\n\u003ch3\u003eWhy shooters choose the ProTac 1L-X USB\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput on SL-B9\u003c\/strong\u003e — 850 lumens, 30,000 candela and a 346 metre beam for 0.5 hours\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput on CR123A\u003c\/strong\u003e — 500 lumens, 18,000 candela and 268 metres for 1.75 hours\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow setting\u003c\/strong\u003e — 100 lumens and 3,400 candela to 117 metres, 4.5 hours on the SL-B9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower\u003c\/strong\u003e — SL-B9 USB rechargeable pack and cord included, CR123A accepted\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting\u003c\/strong\u003e — MIL-STD-1913 Picatinny, with an M-LOK mount in the box\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody\u003c\/strong\u003e — 6000-series aluminium, IP67 with the tail switch fitted, 4.64 in\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat the ProTac 1L-X USB fits\u003c\/h3\u003e\n\u003cp\u003ePicatinny rail sections directly, and M-LOK handguards through the supplied mount — so a modern carbine forend is covered either way.
