Lighting
The standard that tells a board when a fixture needs attention, and it is not "when it goes dark."
Common-area lighting needs service before a bulb goes dark, not after. Industry guidance treats a fixture as due for replacement once light output drops to about 70 percent of its original level. For LEDs, dirt on the lens is now a bigger cause of light loss than bulb wear, so cleaning belongs on its own schedule, separate from relamping.
"Still On" Isn't The Standard
It is tempting to judge a light fixture the same way you judge a light switch: it works, or it doesn't. Lighting maintenance practice does not work that way. Fixtures dim gradually, long before they go dark, and by the time a bulb actually fails, the walkway or parking lot it serves may have been underlit for months.
Trade guidance describing the IES/NALMCO recommended practice for lighting maintenance reports that a light source, including LEDs, should be replaced or the fixture serviced once its output degrades to roughly 70 percent of its original level, well before total failure. Treat that threshold, not a burnt-out bulb, as the trigger for a work order.
Two Different Jobs: Cleaning And Relamping
Older lighting technology got relamped often enough that a maintenance crew was already looking at the fixture regularly. LEDs are built to last much longer, which means they are rarely relamped on the same cycle, and that changes where light loss actually comes from.
The same guidance on LED lumen maintenance notes that because fixtures go untouched for longer, dirt accumulating on the fixture itself can become a bigger source of light loss than the bulb degrading, if cleaning is not scheduled independently of relamping. A board that only budgets for "replace bulbs when they die" is missing the maintenance task that now matters more.
Why This Belongs On The Board's Radar
Dim, unserviced lighting is easy to file under "cosmetic" and push to next quarter. Deferred maintenance in general does not stay in the cost column, it should have happened and did not, and postponing it creates fiscal and safety exposure the association is choosing to carry rather than fix. A dark stairwell or unlit walkway is exactly the kind of deferred item that can turn into a liability question, not just a budget line.
"Preventive, predictive, or corrective maintenance that assets and systems should have undergone but have not yet done so."

Whether the association or an individual owner is responsible for a specific fixture, common-area lighting versus a limited common element like a porch light, depends on the community's own CC&Rs and bylaws. Check the governing documents before assigning the work order.
Check yourself
Answer before you read the explanation, recalling it is what makes it stick.
Parking lot LED fixtures still turn on every night. A board member says nothing needs doing until a bulb goes dark. What does lighting maintenance guidance actually recommend?
LED fixtures are almost never relamped the way older bulbs were. What has become the bigger cause of light loss for LEDs over time?
An owner reports a dim, unserviced light near a stairwell. The board tables it for next quarter's budget meeting. What's actually happening here?

Who is responsible for a given fixture, the association or an individual owner, depends on your CC&Rs and bylaws, not on this lesson. Some jurisdictions and communities also apply their own exterior lighting rules; check local code and your governing documents before setting a schedule.
