Have you ever wanted to be able to carry the brightness of 1000 suns with you where you go? This Streamlight Vulcan Rechargeable 44401 is the flashlight for you. I own a 15,000 square foot warehouse and this flashlight easily illuminates a massive percentage of the building at one time. Now to the battery life the thing just keeps going and going I have had it on for 6 hours straight with no dimness at all. I highly recommend this to anyone who needs to illuminate large areas on a consistent basis. And for the price you really cannot go wrong.
