American Seaboard Exteriors offers light fixture cleaning and relamping. These services optimize the efficiency of your lighting system. Even when your light bulbs are still working, the accumulation of dirt on fixture surfaces tends to reduce lighting quality and luminance. Luminance can be reduced by as much as 20% or more by the effect of this “dirt depreciation,” causing your fixtures to no longer produce at designed levels. While a 20% reduction in light output may not sound like much, when multiplied by the hundreds of fixtures in a grocery store, warehouse, or office, it becomes a huge waste of energy and money!
