Why it matters
Dust and insects inside lenses are visible from below and make a space look older than it is.
More on why it matters
Dirt on lenses and reflectors reduces light output, so a cleaned room often looks brighter without changing a single bulb.
Fixtures are typically skipped by nightly janitorial crews because they require ladders or special tools.
How AELC providers clean light fixtures and troffers
Every provider follows the AELC Source-Control Method: capture the dust, don't move it.
- IdentifyCount fixtures by type, note lens styles and insect buildup, and agree with the facility on switching circuits off where lenses will be opened.
- CaptureVacuum the fixture face and trim with a HEPA source-capture vacuum and soft brush.
- ContainDamp-wipe lenses and louvers with microfiber; where approved, open lenses to remove insects and wipe the inside.
- CleanUse lens-safe cleaners only, never solvents that can cloud acrylic.
- VerifyRestore power, confirm every fixture works and photograph results.

DIY tips between professional visits
- Staff can wipe low fixtures with a barely damp cloth when lights are off and cool.

Safety: when work stops
- Turn fixtures off and let them cool before handling lenses.
- Leave any electrical issue, flicker or damaged wiring to an electrician.

Who needs it most
Light Fixture and Troffer Lens Cleaning: FAQ
Does cleaning light fixtures make a room brighter?
Yes. Dust and film on lenses and reflectors block light, so cleaning often makes a noticeable difference without changing bulbs.
Can you change bulbs while cleaning?
Many providers will swap a bulb with a facility-supplied replacement, but relamping programs and electrical work are separate services.
How do bugs get inside light fixtures?
Insects are attracted to light and enter through small gaps in lenses and housings. Opening and wiping the lens during cleaning removes them.
