received a quote for a retrofit LED lamp

i have now received a quote for one type of light we have in the car parks it is a retrofit led lamp, i am going to work out the total wattage it is currently and what it will be if we switch to these new lamps giving me a wattage saving. from this i will try and work out the cost saving and the cost of the lamps in total.
