Measuring Light Levels, Selecting the Right Ballast & Lamp Combination, and Graphing the Results.

Before this grocery store was retrofitted with energy efficient T8 lamps and Electronic Ballasts, we went in and took light level readings. (In Lumens)

Then we graphed the results using an overlay of the store walls, aisles and check out tellers.

By doing this we were able to match the correct ballast and lamp combination to the fixture.
In areas were there was inadequate light we used a high output combination.
Where there was adequate light we used standard combinations.
Where there was more light than required we de-lamped the fixture.
