When it comes to weapon-mounted lights, two names dominate the conversation: SureFire and Streamlight. Both are trusted by professionals worldwide, and you rarely go wrong with either. The differences are in emphasis — how they balance output, build, size and price. Here is how to choose.
SureFire: the premium benchmark
SureFire built its reputation on rugged, no-compromise lights with tight, far-reaching beams. The Scout Light Pro series (such as the M340 mini and M640 full-size) and the pistol-focused X300 Turbo are known for high candela — the measure of beam intensity and reach — aggressive knurling, and Hard Anodized bodies that shrug off abuse. You pay more, but you get precision optics and a beam that throws. The full line-up is in SureFire weapon lights, with the torches and spares in the wider SureFire range.
Streamlight: performance and value
Streamlight delivers professional-grade output at a more accessible price, with an enormous range covering almost every host and mounting need. The TLR series is the backbone: the TLR-1 HL for rails, the compact TLR-7 and TLR-7A for pistols, and the TLR-8 which adds an integrated laser. Streamlight also leans into rechargeable and multi-fuel options, which lowers running costs over time. Browse the TLR range — our TLR model comparison pins down which one fits which host — or the wider Streamlight catalogue and our rechargeable models.
Output: lumens vs candela
Do not shop on lumens alone. Lumens measure total light output; candela measures beam intensity and therefore how far the light usefully reaches. A 1,000-lumen light with high candela throws far and tight; the same lumens with low candela floods a barn but fades across a field. SureFire's Turbo models chase candela for distance; many Streamlight HL models balance a bright, wide beam for close and general use. Match the tool to your environment — the lumens and candela chart puts real figures against both.

Which should you buy?
- Choose SureFire if you want the longest-throwing beam and the most refined build, and are happy to pay a premium for it — the natural choice for lamping at range and for a rifle Scout Light that lives outdoors.
- Choose Streamlight if you want outstanding output per pound, the widest selection of rail options, and rechargeable running costs — ideal for most shooters kitting out a rimfire, a straight-pull carbine or a practical shotgun. If the light is going on a foxing rifle, our guide to optics for fox and night vermin control covers what actually matters after dark.
Both brands back their lights with strong warranties and years of hard-use reputation. Decide on your host (rifle or shotgun), your environment (barn, wood or open field) and your budget — then match the beam. Browse our SureFire and Streamlight ranges, add a remote switch from weapon light accessories, look at a light and laser combo if you want both jobs in one unit, or ask us for a recommendation for your exact firearm.
