POWERFUL LONG WAVE ULTRAVIOLET BLACK LIGHT features 12 ULTRA VIOLET LEDs.

Comes in an attractive 3-1/2" long gun-metal gray or black body in a one-inch head which throws a broader beam and is manufactured from sturdy "can-take-a-beating" heavy-duty aluminum. Twist the base to turn on or off. Powered by one 1.5 V AA battery which is included. Another great UV light from THE INCURABLE COLLECTOR!

FREE WITH YOUR PURCHASE! INCLUDED ARE 3 FREE GIFTS; A HANDY BLACK WRIST STRAP, ONE FLUORESCENT VASELINE GLASS MARBLE OR A VASELINE GLASS GEM AND AN INFORMATIVE FLIER about black light testing! The marble or VG gem is given to help you learn the principals of fluorescence in jewels, gems, gemstones or minerals when exposed to UV light - as well as being a curiosity and conversation piece.

Better than the fluorescent glass tube type light; this will not break if dropped and the LED has 100,000 hours life. IT IS WATER RESISTANT SO IT WORKS WELL EVEN IN THE RAIN!

I was pleased with this comment from a collector: "I'll recommend this product to my friends; beats the heck out of the cell phone sized one I currently use at the rock and gem shows. "

And here's another enthusiastic feedback: "Sweet field tool - a must have for rockhounds. TYVM. AAA+"

The first one was incandescent long wave & most recently a hand-held neon tube light. Yours out performs them all. I've never seen such brilliance from my fluorescent minerals. I also buy & sell antiques and collectibles. I can't wait to have an extra one and a couple to give as gifts. Thank you!"
