It's a matter of figuring out all of the costs.
How much time and money is needed, if any, to convert the equipment?
This is one of the biggest factors right here. There is a far different cost
if it is a matter of plugging in a new bulb vs rewiring and the like.
Cost of new bulb vs cost of changing the old bulbs.
It takes a certain amount of time to have an employee change the bulbs.
If you are able to do the same job with far less people, this adds up fast.
This is assuming, of course, that new bulbs do at least as good a job as the old
ones. There are problems that will have to be addressed later on regarding
disposal and recycling. The old bulbs are just glass and wire. The new bulbs
contain elements that are potentially toxic, like mercury.
