I would like to recommend a websitewww.convert2xenon.co.ukbecause I find their product images very clear and their prices very reasonable.
depeds on what light bulb it is
how much did a light bulb cost in 1883? I do not know maybe $50.00
It ranges on the watts and what store department you are getting it from. It is cheaper than incandescent. It will save you money and it will pay for itself.
