YES LED type light fixtures are more convenient and less maintenance compare to florescent lamp or HPSV lamp. Another thing is low power consumption and high lumen output.

It is a decision which is required to be evaluated for investment . The following factors are required to be reviewed for your business case:

1) Initial cost of LED fixtures

2) level of illumination required.

3. saving in energy and cost of energy saved

4) reduction in maintenance cost - services and spares

5. Duration of glowing lamps in a day.

Other than the financial factor, it is not recommended to replace LED lighting especially in industrial environments because the LED technology is still evolving and it might not be a wise decision to replace the old or existing systems.

No, there are many factors affect your decision of replacing lighting with LED. You have to do some calculations to find a payback period. One of projects I've worked on, the payback period was around years which was not logical to spend millions replacing all the fixtures to get them after years. Another factor which will  play a role is the quality of the LED fixtures, bad quality means more maintenance and the only way to fix a LED fixture is to replace it with new one. This is a brief answer about financial factor, other factors will play a good role to decide whether to use LED or no, can be discussed in more details.
