Surefire X300 Ultra High Ouput LED Weaponlight Review


The powerful and versatile SureFire X300 Ultra WeaponLight for handguns and long guns features a high-performance LED that generates 500 lumens of stunning white light focused by a Total Internal Reflection (TIR) lens to produce a tight beam with extended reach and significant surround light for peripheral vision. The virtually indestructible and highly efficient LED generates tactical-level light—more than enough to overwhelm an aggressor’s dark-adapted vision—for 1.5 hours per set of batteries.

The X300 Ultra can be attached to a pistol or a long gun since its Rail-Lock® system permits rapid attachment to and removal from either Universal or Picatinny rails. Its high-strength aerospace aluminum body is Mil-Spec hard anodized for superior toughness and is O-ring and gasket sealed to make it weatherproof.

FITS: Handguns and long guns with Picatinny or Universal rails. Adapter mounts available for several non-railed handguns.


The Surefire X-300 Weapon Ultra High Weapon Light is a top choice when considering the purchase of a weapon light.  The X300 has an incredibly high lumen output rate of 500 lumens and a runtime of 1.5 hours.  These are important factors to consider when evaluating a weapon light.  The X300 also features a quick-detach rail clamp for easy assembly and removal with no tools required.  The light can be operated by one finger, which is crucial to the overall performance and reliability of a weapon light.  Another key feature is the sturdy and secure rail mount that is included in the X300 package.

Be weary of rail-mounted weapon lights on the market advertise reliable, secure operation because there are many products on the market that do not have secure mounts and result in poor performance and reliability.  With the X300, you can be confident that this weapon light will meet your expectations and perform at the highest level.  Surefire is also a US company that stands behind their products and provide exceptional service. It is important to consider all of these factors when considering the purchase of a weapon light.
