Museum Exhibit Lighting and UV Protection Audit [FREE PDF]

Museum exhibit lighting poses one of the most significant ongoing threats to collection longevity, as cumulative light exposure—particularly ultraviolet (UV) and infrared (IR) radiation—causes irreversible photochemical degradation in organic materials, dyes, and pigments. NFPA 101 Life Safety Code mandates minimum illumination standards for public gallery spaces, while ADA Title III requires lighting levels that support accessibility for visitors with visual impairments. Balancing conservation-

Estimated Time: 45-60 minutes
Role: Curator
Total Items: 35
Compliance: NFPA 101 Life Safety Code 2021 Edition Section 7.8 (Illumination), ADA Title III 28 CFR Part 36 Section 36.304 (Accessible Facilities), OSHA General Duty Clause Section 5(a)(1) of the OSH Act, EPA Indoor Air Quality Guidelines 40 CFR Part 50, State Fire Marshal Codes – Emergency Lighting Requirements

UV Radiation Measurement and Control

Measure and document ultraviolet radiation levels at artifact surfaces and verify that UV mitigation strategies are in place.

Are UV radiation levels at all artifact surfaces below 75 microwatts per lumen (μW/lm) as measured by a UV meter?
Are UV-filtering sleeves, coatings, or diffusers installed on all fluorescent and halogen light fixtures in the gallery?
Are UV-filtering window films or glazing installed on all natural light sources in the gallery?
Have all UV filter components (films, sleeves, coatings) been inspected for physical degradation or discoloration within the past 90 days?
Are UV sensor or dosimeter readings logged and compared to baseline measurements for trend analysis?

Illuminance Levels and Lux Compliance

Verify that light levels at artifact surfaces comply with conservation standards and visitor accessibility requirements.

Are illuminance levels at light-sensitive artifact surfaces (textiles, works on paper, dyes) at or below 50 lux?
Are illuminance levels at moderately sensitive artifacts (oil paintings, undyed leather, bone) at or below 150 lux?
Are general circulation and visitor pathway areas illuminated to a minimum of 10 footcandles (107 lux) per accessibility requirements?
Are lighting controls (dimmers, occupancy sensors, timers) calibrated to maintain set illuminance levels automatically?
Is a current lighting plan or photometric study on file that documents design illuminance levels for each gallery zone?

Infrared Radiation and Heat Impact Assessment

Evaluate the thermal impact of lighting on artifacts, including surface temperature elevation caused by infrared radiation from light sources.

Is the surface temperature of artifacts measured using a non-contact thermometer, and are readings within 2°F of ambient gallery temperature?
Are LED light sources used throughout the gallery to minimize infrared heat emission at artifact surfaces?
Are any incandescent or halogen fixtures still installed within 24 inches of artifact surfaces?
Have track lighting fixtures been adjusted to eliminate direct beam contact with reflective or heat-absorbing artifact surfaces?
Are fiber optic lighting systems (if installed) inspected for illuminator heat source containment and cable integrity?

Emergency Lighting and Exit Illumination

Inspect all emergency lighting, exit signs, and egress path illumination for compliance with NFPA 101 and State Fire Marshal requirements.

Are all emergency lighting units in the gallery tested and confirmed to activate within 10 seconds of simulated power failure?
Do all exit signs in this gallery illuminate clearly and are they visible from all required viewing distances?
Are emergency lighting battery backup units within their rated service life and showing green charge status indicators?
Are egress pathways from all gallery areas illuminated to a minimum of 1.0 footcandle at floor level?
Have all emergency lighting units been included in the annual State Fire Marshal inspection records for this facility?

Natural Daylight and Skylight Management

Evaluate the control and management of natural daylight entering the gallery through windows, skylights, and clerestory openings.

Are motorized or manual blinds, shades, or louvers operational on all natural light apertures in the gallery?
Is direct sunlight penetration onto artifact surfaces prevented at all times during gallery operating hours?
Are skylight or clerestory UV filter glazing panels intact with no cracks, delamination, or yellowing?
Are lux levels from natural daylight sources measured and confirmed to be within conservation limits before exhibit opening each day?
Is a seasonal daylight management schedule documented and followed that adjusts shading and supplemental lighting by time of year?

Lighting Fixture Condition and Maintenance

Inspect the physical condition, cleanliness, and maintenance status of all gallery lighting fixtures and associated hardware.

Are all gallery lighting fixtures securely mounted with no loose housings, exposed wiring, or damaged conduit?
Are track lighting rails and accent fixture mounting points free from corrosion, dust accumulation, or heat discoloration?
Have LED drivers and control gear been inspected within the past 12 months and replaced where end-of-life indicators are present?
Are all lighting control panels, dimmers, and scene presets accessible and labeled clearly for authorized staff use?
Attach photo documentation of any damaged, non-compliant, or flagged lighting fixtures observed during this audit:

Light Exposure Budget Tracking and Conservation Records

Review cumulative light exposure records for light-sensitive collections and assess compliance with institutional exposure limits.

Is a light exposure budget (measured in lux-hours per year) maintained for each light-sensitive collection item or gallery zone?
Have any items in this gallery exceeded 75% of their annual light exposure budget for the current calendar year?
Are color change indicator cards or blue wool standards deployed in the gallery to visually monitor cumulative light damage?
Have any light-related conservation concerns been communicated to the conservator or registrar within the past inspection cycle?
Please document any corrective actions, lighting adjustments, or conservation referrals resulting from this audit:
