The TK50 255-Lumens Flashlight (Black) from Fenix Flashlight is an amazingly bright, waterproof flashlight with runtimes that vary from 2.75 to 480 hours, depending on the output used. This powerful light is made from aircraft-grade aluminum in a premium type III hard anodized anti-abrasive finish. Seven output levels in two modes can be accessed by the two side button switches. There are 4 constant light levels from 4 to 255 lumens, and 3 flashing modes--a strobe mode at 255 lumens, warning flashing at 70 lumens, and an SOS signal at 70 lumens.

The output is digitally regulated to maintain constant brightness, and there's reverse polarity protection to protect against improper battery installation. The TK50 operates on 2x "D" batteries. The LED lamp has an approximate life of 50,000 hours. All of this in a flashlight that weighs only 8.2 oz (233 g)!

        I can not say enough good things about this light! If you are looking for a strong led flashlight that runs off d batteries this is the one for you! Bought one two years ago for $(superior light!) and when b&h put it on sale for $, i could not resist to get my dad one for fathers day! He loves his and mine has survived the punishment i have given it. If you want a bright,durable,worthy light don't hesitate to buy this one! Its so bright its like a light saber at night!
