Stretching Those Lamp Dollars, Part 3

We closed Part 2 with “Ask your distributor to help you find a lighting survey expert.” But what exactly can this person do for you?

Among other things, a trained lighting evaluator will look at the quality of the lighting. For example, you may have enough lumens at a given spot but you may also have glare or other problems that impede operators. Some of those other problems include shadows, color rendition problems, overlighting, and underlighting.

You want this person to provide you with recommendations for changes to maintenance practices, luminaire relocation (e.g., moving a light two feet to the right so the operator can see properly), and lighting upgrades.

Begin with a lighting audit of the facility, so you can get a grasp on what the costs are and where to prioritize. Any safety issues will need to be addressed first. These include emergency exit paths, walkway illumination, and lighting problems that (typically due to shadows) impede safe operation of equipment. Once all of these issues are addressed, then prioritization should be based on revenue/cost evaluations.

To get a complete cost picture, you’ll need your lighting expert to clearly define the lighting deficiency, then analyze the available lighting choices to solve those. The analysis must include lamp disposal issues, warranties, utility rebates, power quality issues (e.g., power factor vs. other selection factors), and maintenance cost (e.g., the effect of the shade/lens combination on cleaning frequency).

In Part 4, we’ll look at how to save you money.
