Lamp maintenace program

[Goroon]

The question is: ?What do you see that works for you guys? or ?What Does Not??:roll:
**** Experience supersedes a ?Sales? guy any time.****

Recently I was asked if the lighting lamps should be replaced every 2 or 3 years.
I explained that I would need more information, specifically what lights? They are attempting to both retrofit and contract out re-lamping and are looking for ?work cycle? with ?criteria?.

We (the plant) has T12, T8, T5, CFL, Metal Halide, Mercury, Sodium, ?..

I explained that one person prefers to re-lamp on a ?2 year Cycle? and the next person every 4. In both of those scenarios, no one (seems to) repair the lamps or ballast that fail after 2-3 months while only repairing those that did not start.

Some others I have talked to use a 10% rule, when 10% are bad in an area, all get replaced.


We are a Heavy Industrial sight, lots of Drives, few Operators, ?Automated Systems?.
Almost all lighting in those areas are served through isolation transformers of 30-45 KVA 480- 277 Delta WYE specific.

someone needs to do a cost analysis on what method is cheaper, while still maintaining safe work environment. areas should be divided into catagories, so that an unsafe condition doesn't exist if particular lighting is not sufficient, and a general plan (based on cost analysis) done for the general portion of lighting. It sounds like there should be enough history at the plant to go back through the records and costs and make a reasonable assesment. the cost of the person doing the assesment itself should also be taken into account, and added to a future cycle as well so that reassessment at given intervals becomes part of the task itself, in case the working parameters/costs change.
