I've worked in many careers including as a home inspector before the great housing crash. I used maglite brand which have been the standard in flash lights for the past twenty five or so years. The flash lights worked fairly well but replacing four d-cell batteries Several times a week was expensive and wasteful. I switched to streamlite rechargeable flash lights which Were great quality but we're also very expensive. The light lasted about four hours before I would have to plug in and recharge it. I needed about 6 to 8 hours of flash light use per day and having to wait for my streamlite to recharge was a bit annoying. I wish I had this light then! What a difference it would have made in my day to day operations. I have found that the light does tend to tip over if stood on end and positioned on an 45 degree angle. To remedy this I switched to 20volt 6ah xr batteries which are heavier and have a larger base. They even last a lot longer (over 8 hours) than the smaller batteries. If you truly need a great spot light for work or home, this may be the last one you will ever have to buy.
