The Streamlight ProTac 2.0 Rail Mount, part 89003, is a rechargeable long gun light producing 2000 lumens and 17,700 candela for a 266 metre beam, supplied here as the light-only package.
Read the part number before you buy: 89003 is the light on its own, worked from the tail cap, with no remote pressure switch in the box.
The high setting gives 2000 lumens, 17,700 candela and 266 metres for 2.5 hours; the low setting drops to 250 lumens, 2,150 candela and 93 metres and runs for 11 hours, and the strobe lasts 4.5 hours. Power is Streamlight's SL-B50 USB-C rechargeable lithium-ion pack, included along with the charging cord. The head is TEN-TAP programmable so the mode sequence can be changed, the body is Type II MIL-spec anodised aluminium rated IP67 for dust and one metre of water for thirty minutes, and it measures 6.30 in (16.0 cm) and weighs 9.06 oz (257 g).
This is a general-purpose rifle light rather than a specialist one: 17,700 candela puts a defined hotspot on something at distance while leaving plenty of spill to see what is either side of it, which is what you want checking a hedgerow or a building. If you need identification much further out, the HP version concentrates the same 2000 lumens far more tightly, and if you want a pressure pad on the handguard you want the system package instead.
It clamps directly to a MIL-STD-1913 Picatinny rail, and the included M-LOK mount covers an M-LOK handguard without buying an adapter. For the same light with a straight momentary remote pressure switch and its hardware, take the ProTac 2.0 Rail Mount system, 89009. For long throw instead of a balanced beam, the ProTac 2.0 Rail Mount HP at 85,000 candela is the one. Our M-LOK versus Picatinny guide covers the mounting choice.
