Review: Smith & Wesson CS-10

The Smith & Wesson® Delta Force CS-10 flashlight is a very small flashlight that generates 130 lumens using a single AA battery. It is billed as a tactical flash but at 4″ I consider it too small to be used as a practical, tactical flashlight. I prefer a flashlight that extends past my palm when held tightly in my hand. The CS-10 is a good choice for those who need a bright, rugged, waterproof, and very compact flashlight that uses a standard AA battery. It has high, low, and strobe modes available in both momentary and sustained ON. It also has a semi-aggressive front strike bezel. The CREE XBH LED generates a 130 lumens beam that lasts for nearly 4.25 hours.

  • Construction: Machined from aircraft grade aluminum, fairly aggressive front strike bezel (no rear strike bezel), hard anodized finished, and steel pocket double clip
  • Size: 4″ long, head 0.82″, 2.05 oz.
  • Waterproof: IPX7 (waterproof to 1 meter for 30 minutes)
  • Durability: Withstands 1-meter drop
  • Features: High/low/strobe modes in momentary or sustained ON
  • Light Output: (high) 130 Lumens for 4.25 hours, (low) 20 lumens for 9.5 hours
  • Beam Pattern: 41″ x 6″ at 3′ (Beam Scale)
  • Power: 1 AA battery


I prefer flashlights that are larger and fit across the palm of my hand. Advantages of the CS-10 include compact size, bright (130 lumens), very long runtime, and it uses a single AA battery. I would NOT use this flashlight as a tactical everyday carry (EDC) light but it would make a good utility or backup light especially if you need small size and light weight. This light has decent brightness, uses a standard battery, and has a long runtime.
