Typically a 50 watt LED is equivalent to a 500 Watt Halogen - giving the same light output but burning far less energy and therefore costing a lot less to run.
You will need to check the lumens - i.e. how much light is thrown out. This does come with a warning. If you are looking at halogen or metal halide, it is non directional, meaning that you have light spilled and therefore 50 to 70% of light is wasted, shining 360 degrees whereas your LED is directed light.
