If you’re planning a campus-wide LED upgrade, the fastest way to get it right is to specify by area. Different spaces have very different visual tasks, glare risks, and control needs. This guide gives practical, standards‑aware ranges you can take straight into design or procurement.
We focus on two priorities: visual comfort (keep glare low and flicker minimal) and controllability (0–10V/DALI/wireless with occupancy/daylight/scenes). To keep things actionable, we provide ranges for illuminance (lux/fc), UGR guidance, CRI/CCT suggestions, fixture types, and controls per area. Where helpful, we point to authoritative, recent references.
Soft CTA: Need a quick classroom/corridor spec? You can reference low‑glare panel and linear options from established vendors. For example, KEOU Lighting offers control‑ready panels/linears with microprismatic or honeycomb optics; see the internal guide link in Section 3.1.

Jump to Section 3.0 for per‑area specs. Use the comparison table (Section 4.0) as a quick reference.
Apply the pricing/caveats (Section 5.0) when assembling budgets and selecting supply models.
Use controls and commissioning steps (Section 7.0) to lock in savings and comfort long‑term.
We synthesized practical ranges from recent technical guidance and standards summaries, then weighted decisions using the following criteria: visual comfort and glare control; controls readiness and system integration; illuminance efficacy and uniformity; customization and project fit; build quality and durability; value and TCO; evidence transparency.
Key references include the U.S. Department of Energy’s 2024 Lighting Specification Guidance for Schools and recent summaries of EN 12464‑1 for interior lighting. For outdoor and gym spaces, we referenced credible industry guidelines and university standards where appropriate.

Scenario: A 900 ft⊃2; (≈84 m²) classroom, 9‑ft mounting height, retrofitting from four aging 2×4 troffers to LED panels with low‑glare optics.
Target: 350–400 lux average at desks with ≤19 glare feel, daylight zone along windows, two scenes (lecture, AV).
Selection: Four 2×4 panels at ~4,000–4,800 lm each with microprismatic lenses; 0–10V drivers; one photocell/daylight sensor in the window zone; vacancy sensors.
Result (modeled): ≈370 lux average with good uniformity; dim to 150–200 lux for AV; daylight zone reduces output ~20–40% on bright days.
Energy: From ~4×64 W T8 troffers (≈256 W) to ~4×38 W panels (≈152 W) before controls; additional savings from vacancy/daylight.
Commissioning notes: Define scenes at handover; set vacancy timeout to 10 minutes; verify no flicker at low dim levels.
Choose protocols early: 0–10V for simplicity; DALI‑2 or wireless ecosystems for granular scenes and monitoring.
Zoning: Separate teaching walls, window rows, and back rows in classrooms; bi‑level with auto‑dim in corridors; scene zones in auditoriums/gyms.
Sensor placement: Mount occupancy sensors to see entry paths without false trips; place daylight sensors in representative daylight zones.
Commissioning checklist: Verify max/min levels, timeout settings, and scene recalls; test emergency lighting and egress illumination; document setpoints for maintenance.
According to the U.S. DOE’s 2024 schools guidance, vacancy mode (manual on, auto off) with daylight zones is a practical default in classrooms and offices, while corridors benefit from automatic bi‑level reduction when vacant. See details in the DOE Lighting Specification Guidance for Schools (2024).
Achieving UGR ≤19 in classrooms/offices: Favor microprismatic or honeycomb optics; avoid high‑brightness cutouts in sightlines; increase spacing or lower output per luminaire and add more units if needed to keep luminance down.
SMH rules of thumb: Start with manufacturer SMH guidance; check uniformity at desk height and along whiteboards; adjust row spacing if bright scallops appear.
Retrofit mounting: For old fluorescent grids, choose panel/troffer sizes that match openings; confirm driver clearance and ceiling plenum access before ordering.
Outdoor glare/pollution: Use full‑cutoff optics and ≤3000–3500K CCT; schedule reductions after hours to protect neighbors and the night sky. For principles and strategies, see the DarkSky outdoor lighting principles and the DLC’s strategies to minimize impacts at night (2024).
Aim for 300–500 lux (30–50 fc) on the desk plane with dimming and scenes to suit activities.
It’s a widely used comfort target for classrooms/offices. If screens or glossy surfaces dominate, push glare even lower with better optics and layout.
Neutral white (3500–4000K) is a good balance for focus; tunable white can support different activities if commissioning is done well.
Vacancy/occupancy with short timeouts and daylight zones routinely cut runtime; corridors can auto‑dim to ~50% when vacant. Quality commissioning is the key to realizing savings.
2×4 or 2×2 LED panels/troffers are the usual drop‑in choices. Verify opening size, plenum clearance, and driver location; choose low‑glare optics to maintain comfort.
