The body is Mil-Spec hard anodised aerospace aluminium, rated IPX7, at 3.76in (9.55 cm) long with a 1.125in (2.9 cm) bezel and a weight of 4.1 oz (116 g) with batteries fitted.\u003c\/p\u003e\n\u003cp\u003eThe B in the part number is the mounting method: a thumbscrew clamp rather than the lever-indexed Rail-Lock system on the A version. It takes longer to fit and it grips harder, which is the trade you are making. Note the beam profile too — 11,300 candela is a working light rather than a long-range lamp, so it fills a room and identifies at moderate distance rather than reaching across a field.\u003c\/p\u003e\n\u003ch3\u003eWhy shooters choose the X300U-B\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput\u003c\/strong\u003e — 1000 lumens with 11,300 candela, for approximately 213 metres\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRuntime\u003c\/strong\u003e — approximately 1.25 hours on two CR123A lithium cells\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount\u003c\/strong\u003e — T-slot thumbscrew clamp for Universal and Picatinny rails\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuild\u003c\/strong\u003e — Mil-Spec hard anodised aerospace aluminium, rated IPX7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e — 3.76in (9.55 cm) long with a 1.125in (2.9 cm) bezel, 4.1 oz (116 g) with batteries\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat the X300U-B fits\u003c\/h3\u003e\n\u003cp\u003eIt suits any host carrying a Universal or Picatinny accessory rail, from a railed pistol dust cover to a carbine forend.
