OLIGHT Baldr S Blue Beam Tactical Flashlight - Compact 800 Lumen Beam

In this review the OLIGHT Baldr S Blue Beam is evaluated as a compact, rail-mounted tactical light best suited for handgun owners and tactical shooters who want a powerful white beam with a subdued but useful blue aiming/identification beam. The single biggest reason to buy is its blend of reliable 800-lumen white output and a low-power blue beam under 5mW that improves target acquisition at close range without the glare of stronger GL-style lasers. The review focuses on real-world fit, runtime, operation and compatibility.

Key Features

• 800 lumen white output: Delivers a bright, focused white beam that lights target areas clearly at typical defensive engagement distances.
• Blue beam under 5mW: Provides a noticeable blue aiming reference that is brighter than a standard RL beam but less glaring at close range than a GL beam.
• Rechargeable battery: Built-in 3.7V 380mAh lithium polymer cell charges via magnetic USB and supports up to 140 minutes at 100 lumens for extended training or duty use.
• Dual ambidextrous switches: Smooth, easy activation from either side allows quick transient or constant-on operation with either hand.
• Rail compatibility: Ships with GL and Picatinny sized rail inserts to fit a wide range of pistols and compact rails without modifications.

Who It's For

The Baldr S Blue Beam is ideal for firearm owners who want a compact weapon light that combines a strong white illumination with a subdued blue aiming beam, particularly useful for close-range identification and target alignment without an overly aggressive laser. It also fits shooters who prefer a rechargeable, magnetic USB power system and a light that mounts securely on both GL and Picatinny rails.

Those who should look elsewhere include users who require a high-power aiming laser for long-distance designation or medical/utility users who need specialized colored outputs beyond the included blue and white combo. Also, if runtime beyond the stated 140 minutes at 100 lumens is a strict requirement, separate larger-battery solutions may be more appropriate.

Pros & Cons

Pros

• Bright, usable 800-lumen white output that performs well in defensive and low-light scenarios.
• Blue beam under 5mW gives clearer short-range aiming without excessive glare.
• Rechargeable 3.7V 380mAh battery with magnetic USB is convenient and holds charge well.
• Compatibility with both GL and Picatinny rails and easy ambidextrous controls make mounting and operation straightforward.

Cons

• Battery capacity is modest compared with full-size weapon lights, so heavy continuous use will reduce runtime.
• The blue beam is purposefully subdued for close-range use and will not replace high-power designation lasers at distance.
