UltraFire WF-502B 3W UV Voilet 395~400nm LED Flashlight(1x18650/2xCR123A)

• Other Thoughts: Very bright, light weight and handy. LOVE IT!

• Pros: Detects urine, oily handprints, and any other thing that glows under UV light. It's also great for instantly charging up any glow-in-the dark surfaces like watch dials. Lots of fun but not good if you easily get grossed out -- you'll be cleaning your house forever.
• Cons: The UV drop-in doesn't make great physical contact with the flashlight body so the LED doesn't have a terribly effective heatsink. Then again, a UV light probably isn't going to be used for long periods at a time unless you're an evidence detective.
• Other Thoughts: I use it as a conversation starter and to quickly check if our dog has pee'd inside the house.

• Other Thoughts: This is a great little flashlight it does a great job and is very bright. This is a great deal worth every penny!!

• Other Thoughts: This is indeed a great little flashlight and a terrific value. I am a park ranger and use this light every evening to secure and close the park I work in. It's small enough to fit comfortably in a pocket and bright enough for almost any reasonably close-up task. It's held up well to exposure to sand and salt and I'm still on the first set of batteries after almost two months of regular use!

• Other Thoughts: Very tiny flashlight. Fits in palm of my hand (the whole thing). I was thinking it would be bigger. That being said, it's brighter than anything I've used to date, so I am impressed. No problems.
