01

Most requested

Photometric plans & permit reports

Code-focused photometric calculations for parking lots, warehouses, gas stations, car washes, signage, commercial sites, sports fields, and exterior projects.

  • Point-by-point foot-candle or lux grids
  • Min / average / max values and uniformity
  • Fixture schedule, mounting, optics, and aiming
  • Light trespass, shielding, and review corrections
02

Architecture

Lighting layouts & coordination

Complete fixture placement for residential, hospitality, workplace, retail, and mixed-use spaces—developed around function, architecture, and visual comfort.

  • Fixture placement and spacing
  • Mounting heights and aiming angles
  • Layered ambient, task, and accent lighting
  • Technical coordination with plans and reflected ceilings
03

Visualization

3D lighting renders

Realistic visual studies that show how the proposed lighting interacts with materials, architecture, shadow, and atmosphere before construction.

  • Interior and exterior scenes
  • Light distribution and shadow studies
  • Material response and color temperature
  • Client presentation visuals
04

Specification

Fixture & optics consulting

Independent guidance for fixture selection, lumen packages, beam angles, photometric files, glare control, and application suitability.

  • IES file and distribution review
  • Beam angle and optic selection
  • Lumen output and mounting coordination
  • Value-engineering alternatives
05

Compliance

Emergency, glare & code analysis

Targeted calculations for emergency lighting, UGR, BUG ratings, property-line spill, dark-sky requirements, and local illumination criteria.

  • Emergency lighting simulations
  • UGR and visual comfort review
  • BUG rating and uplight control
  • Property-line and trespass calculations
06

Special applications

Outdoor & sports lighting

Performance-focused calculations for courts, fields, façades, roadways, industrial sites, and large exterior areas where uniformity and glare matter.

Common questions

Before you send the project.

Can you fix a photometric plan that failed review?

Yes. Send the previous plan and reviewer comments. We can adjust fixture layout, optics, shielding, and calculations around the specific issue.

Do I need to know the target light levels?

No. If a target or code requirement is available, include it. Otherwise, send the project type and location so the criteria can be reviewed.

Can you recommend fixtures and optics?

Yes. Stetra can review IES files, lumen packages, beam angles, mounting heights, shielding, and application suitability.

What format will I receive?

Deliverables are scoped per project and typically include a clear PDF report with the lighting layout, calculation grid, summary values, and relevant notes.
