I bought this item to replace a dusk to dawn light that I have had for some years. Some reviews say its fiddly to get the front cover off as you have to prize it apart with a screw driver, well this is a similar design as my old one although a different make so that was no problem, quite easy once you get the knack. One review I read said they understood this light is for indoor use only, if that's the case why is it advertised as weather & corrosion resistant? I have installed it on the end of my shed, it's an ideal safety / security device. My opinion is it's a good solid easy to install practical very reasonably priced product.
