the SSL era
ALL LIGHT SOURCES
must be maintained; as lighting controls
become more sophisticated, they also must be
maintained. Responsible lighting design should
include maintenance to preserve design integrity.
In terms of sustainability, whether the lighting goal
is visual comfort, highlighting merchandise, energy
savings or anything else, maintenance is where the rubber meets the road.
Lighting maintenance may involve relamping luminaires,
cleaning luminaires and room surfaces, troubleshooting and
replacing defective parts, and re-aiming directional lamps and
luminaires. It may also include periodically inspecting and
reprogramming or recalibrating controls.
In the solid-state lighting (SSL) era, is this still necessary?
Some early light-emitting diode (LED) sales claims promised
“install and forget” lighting. For building owners whose main
concern is whether the lights are on, a 20-year light source that
doesn’t require spot relamping may certainly seem that way.
The truth is that LED lighting should be maintained, though
maintenance best practices must be adapted to accommodate
this light source’s unique characteristics.
LEDs are a long-life light source, which is a major benefit.
