This is the most durable light I have ever come across. I bought a few of these to use as auxiliary lighting in areas of my home, like a desk or bookshelf. I took one of the lamps outside near my hot tub one night so I could have lighting while I was applying the chemicals. I accidentally left the light attached to the hot tub and it has been there for over a year. Through rain, extreme heat, extreme cold, blizzards, ice storms, and soaking hands from the hot tub. This little light has not failed yet. It is still as bright as the day it arrived even though it's gone through one heck of a beating.
