I be very excite to get this light ... initially , I like it . out of the packaging , I hook it up to the 18v battery and it work , emit a fairly bright beam . the sale ad say that it come with a `` extra '' bulb , which be not include . I email Amazon regard the issue and they send a 2nd light to my address , instead of send a bulb or two -lrb- ? -rrb- . it be worth mention the the re-ship do not have the extra bulb either . I have pretty much decide to just purchase the other light as well , think I could use one and leave one in the work truck as a spare . then , I be use one of the light , hit it pretty hard with a board I be use in a attic , and it fizzle . I go and get the other light , use it the rest of the morning , then go to use it in the afternoon and it be burn out too - with little to no abuse -lrb- that I can remember -rrb- . I send both of the light back - they be not as durable as they should be . instead , I order two of the flexible-head light -lrb- Dewalt 18V -rrb- . a few of my friend have these and have have no issue . I will leave a review for those as well when I have have time to put they to the test . all in all , this be a bright light , but if you put you equipment to the test day-in and day-out , it might not be the quality you be look for .
