Introducing the latest design UTG Tactical Flashlights.  These shockproof lights feature LED's that won't break under recoil and offer 50,000 hours of life!  They are an excellent value and offer lifetime warranty. The CREE LED uses less power (lasts longer 120 minutes vs 70 for Xenon) and will essentially never need to be replaced (last about 50-100,000 hours vs Xenon approximate 20,000).  Both last a LONG time but LED is a big jump.  The Xenon bulb while brighter and more durable than Halogen is not as bright or durable/shock resistant as an LED either.
