The Data at a Glance

Here are the most notable weapon lights ranked by community engagement on r/gundeals:

Best Handgun Lights — Summary

SureFire X300U — The #1 Most Upvoted Weapon Light

The SureFire X300U is the gold standard of handgun lights with 203 average upvotes — by far the highest community engagement of any weapon light. It's the light that virtually every holster company designs around first. 1,000 lumens, bombproof reliability, and unmatched holster support make it the default recommendation for full-size duty guns like the Glock 17.

Streamlight TLR-7A — Most Frequently Posted

With 49 tracked deals, the Streamlight TLR-7A is the most frequently posted weapon light on r/gundeals. Its compact form factor makes it the go-to for the Glock 19 and similar compact carry guns. At 500 lumens, it's plenty for indoor defense distances.

Holosun P.ID — The Budget King

At under $49, the Holosun P.ID is the most exciting new entry in the weapon light market. With a rechargeable battery and solid output, it's hard to argue against at this price point. The 94 average upvotes from just 3 deals show the community is paying attention. A great option for shooters on a budget who still want a quality light.

Best Rifle Lights — Summary

Cloud Defensive Rein — Best Rifle Light Overall

With 166 average upvotes, the Cloud Defensive Rein generates massive excitement when deals drop. The complete kit approach (light + tape switch + mount + battery) means no hunting for compatible accessories. Outstanding output with excellent throw and spill balance.

Streamlight ProTac HLX — Best Budget Rifle Light

The ProTac HLX is the rifle equivalent of the TLR-1 — Streamlight's budget-king approach applied to long guns. At 1,000 lumens with an included tape switch, it's a complete rifle light setup under $70. It won't match the candela of a Cloud Defensive or Modlite, but it's more than adequate for home defense distances.

How to Choose: Lumens vs Candela

Two specs matter most in weapon lights:

• Lumens = total light output. More lumens means more overall brightness. Important for flood/spill.
• Candela = beam intensity at the center. Higher candela means more throw/distance. Important for identifying targets at range.

For home defense at indoor distances (0-25 yards), lumens matter more — you want to flood a room. For outdoor or longer-distance use, candela is king. The SureFire X300U and Cloud Defensive Rein both excel at high candela, which is part of why they're so popular.

Budget Tiers — What to Buy at Every Price Point

Under $50

Holosun P.ID for handguns. Nothing else at this price comes close. For rifles, watch for Streamlight HLX holiday sales.

$50-$100

Streamlight TLR-1 HL for full-size handguns. Streamlight ProTac HLX for rifles. Both are proven, reliable, and well-supported by holster and mount makers.

$100-$175

Streamlight TLR-7A for compact handgun carry. Cloud Defensive Rein on sale for rifles.

$175-$300

SureFire X300U for handguns. Cloud Defensive Rein 2.0 complete kit or Modlite PLHv2 setup for rifles.

Final Recommendations

The data is clear: the SureFire X300U is the king of handgun lights, and the Cloud Defensive Rein leads the rifle light category. But the Holosun P.ID at $49 is the most exciting value play, and Streamlight continues to dominate the budget space with the TLR-7A, TLR-1 HL, and ProTac HLX.
