Of note, you must use 18650 lithium-ion batteries. Using a CR123A battery will overheat and burn out the bulb.
YallStore via eBay continues to offer the UltraFire CREE LED Flashlight, model no. WF-502B, bundled with a rechargeable lithium-ion 18650 battery and charger for $15.99 with free shipping. That's tied with our mention from last week and the lowest total price we could find by a buck for these items purchased separately elsewhere. This 5.25" flashlight features 1,000 lumens of brightness.
