The Picks, With a Verdict on Each

Best Overall: Streamlight ProTac Rail Mount HL-X Laser

The HL-X Laser puts the same 1,000 lumen HL-X light and an aiming laser in one rail mounted body, and it comes with a tape switch so you can run it from your support hand. You get a light and a laser on the rifle for not much more than the plain HL-X costs.

It's the light to buy if you want a laser and don't want to give up the HL-X's output to get one. Builders agreed: it took 23.6% of weapon light picks, more than twice the share of the plain HL-X in second place.

What we like

• The listing rates it at 1,000 lumens, the same output as the plain HL-X, with a laser added.
• It's sold with a tape switch, so a handguard mounted pad is in the box.
• It's about $155 to $195 at the stores we track and in stock at most of them.

Watch out for

• Our listing for this CR123A version doesn't state the laser color or class. The listing for the rechargeable SL-B26 version describes a red laser, so check the card before you order.
• It's heavier than the plain HL-X in our catalog, so expect more weight out on the handguard.
• A laser has to be zeroed to your sights like any other aiming device, which takes range time.

Best Without a Laser: Streamlight ProTac Rail Mount HL-X

The HL-X clamps straight to a Picatinny rail and puts out 1,000 lumens. It ships with both a push button tail switch and a remote pressure switch, so you can run it from the tailcap or tape the pad where your support hand already sits. You don't have to buy anything else to get a working setup.

It's the light to buy if you want one box that does the whole job at a fair price and you don't need a laser. It was the second most picked light at 10.7%.

What we like

• Streamlight lists 1,000 lumens and three programs you set with its TEN-TAP system: high, strobe and low; high only; or low and high.
• It runs on two CR123A batteries, which come in the box, or one Streamlight 18650 rechargeable cell.
• The box includes the remote pressure switch, the tail switch, clips, tape and zip ties, according to the listing.

Watch out for

• Streamlight rates it IPX7 with the standard button, but only IPX4 with the remote pressure switch installed.
• The integrated clamp fits MIL-STD-1913 rails. On an M-LOK handguard you'll need a short rail section or an offset mount.
• Prices run from about $120 to $155 across the stores we track, so check the card for the low one.

Best Premium Light: SureFire X300 Turbo

The X300 Turbo trades raw lumens for a tight, far reaching beam. SureFire lists it at 650 lumens and 66,000 candela, focused through a smooth parabolic reflector. Candela measures how hard the light punches at the center of the beam, so this light reaches farther than lights with higher lumen numbers.

It's the pick if you want SureFire's build and you need to identify something across a yard rather than across a room. It was the third most picked light at 8.7% of light picks, and that's the tan version alone.

What we like

• At 66,000 candela, it has the hardest hitting beam on this page by its listed specs.
• Its ambidextrous switch sits at the rear of the body, so you can work it with one finger from either side.
• It runs on CR123A batteries and has an aluminum body.

Watch out for

• You'll pay about $320 to $360, more than twice the price of the HL-X.
• The rear switch sits right behind the light. On a rifle you'll likely want a SureFire remote pressure switch, sold separately.
• At 650 lumens, it lights up a room less than the HL-X or the Odin Mini.

Best Visible and IR Laser Combo: Sightmark LoPro Light and Green Laser

The LoPro puts a light, a visible green laser and an infrared laser in one housing that mounts to a Picatinny rail. The IR laser only matters if you run night vision, but you get it whether you use it or not.

Pick it if you want a green laser and an IR laser on the rifle without paying for a dedicated aiming unit. It was the fourth most picked light at 7.3%.

What we like

• You get a visible green laser and an IR laser in the same unit, per the listing.
• It mounts to a Picatinny rail, per the listing.
• It's about $240 at every store we track that has it in stock.

Watch out for

• Our listing gives no lumen rating, so you can't compare its output with the HL-X from the card.
• It's heavier than the HL-X Laser in our catalog, so it adds more weight out front.
• The LoPro Mini is a different, smaller unit. Check the card name so you get the full size version.

Best Rechargeable: Olight Odin Mini

The Odin Mini runs on Olight's own rechargeable battery, so you never swap cells. Our catalog lists it at 1,250 lumens with an aluminum body and a rail mount.

It suits a home defense rifle that sits in a safe between range trips, where you'd rather top it off on a charger than keep a drawer of CR123As. At 2.2% of light picks it's well behind the leaders, but it's still the most picked light built around a rechargeable battery.

What we like

• At 1,250 lumens, it's the brightest light on this page by its listed output.
• It's about $140 at every store we track, so there's little reason to shop around.
• The aluminum body and rail mount are listed in our catalog.

Watch out for

• The battery is proprietary. If it dies at the range, you can't drop in a spare CR123A the way you can with the HL-X.
• This card is the rail mount version. Olight also sells an M-LOK mount version, so check the name before you order.
• Our catalog doesn't list which switch comes in this box, so check the card before you order.

Which Brands Do Builders Trust?

Streamlight leads at 48.7% of light picks July through September 2026, and SureFire follows at 28.2%. Sightmark is third at 10.3% and Olight fourth at 4.5%. No other brand reaches 3%.

The Streamlight TLR-1 HL Dual Remote Kit on the chart took 6.7%, fifth overall. It's a 1,000 lumen light that runs on two CR123A batteries, and it runs about $200 to $275 at the stores we track. We don't card it because the HL-X gives you the same listed output and a remote switch for less.

Lumens or Candela?

Lumens measure the total light a unit puts out. Candela measures how intense the center of the beam is. A high lumen, low candela light floods a hallway. A high candela light throws a tight spot farther down a field.

Indoors, almost any light on this page has enough output. Outdoors, past 50 yards or so, candela matters more. That's the split between the Odin Mini and the X300 Turbo.

How We Pick

Each pick is the weapon light that builders added to a GunPartPicker build most often for its job or price band. Every spec comes from the product's own listing or the maker, and the prices on the cards are live.
