Photometric Design and LightingEngineering for Commercial Permitting.

A photometric plan is a lighting layout and calculation package that shows how light will perform across a site. Think of it as a heat map for light: it documents fixture placement, measured illumination levels, and the compliance information your permitting authority reviews.

Each plan includes the site overlay, point-by-point foot-candle grid, iso-footcandle contours, fixture schedule, code-specific compliance summary, property-line trespass calculations, BUG ratings, and the included revision rounds for your project.

Yes. Our work is manufacturer-agnostic. We can design around a fixture family you already intend to use, or we can evaluate alternatives that satisfy your performance and code requirements.

Standard delivery is 48 hours for most projects. We also offer 24-hour rush service and same-day delivery when the schedule requires it.

Yes. We review the applicable jurisdiction requirements and model the plan to the illumination, uniformity, cutoff, or dark-sky standards that govern your project.

Yes. Two revision rounds are included in most project scopes, and additional revision rounds can be added when a jurisdiction or owner review requires more iteration.

PE stamps are available as an add-on when the jurisdiction or project team requires licensed certification. We scope that separately because the requirement varies by state and project type.

Usually, yes. We can start from CAD, PDF, a fixture schedule, a marked-up site plan, or even a phone photo of the layout. If anything critical is missing, we will identify it before we begin modeling.

Yes. We support new developments, retrofit permitting, fixture replacements, property upgrades, and projects where an existing site must be brought into compliance.

We accept PDF, DWG, DXF, JPG, JPEG, and PNG files up to 25MB through the project form. If the file set is larger or the project is already in motion, you can also email the plans directly to us.

Yes. We produce NEC Article 220 electrical load calculations and DOE COMcheck energy code compliance certificates alongside the photometric plan. Most commercial lighting permits require these documents, and we scope them together so the submittal package is complete.

Yes. Many clients arrive without a fixture layout. We design fixture placement, spacing, distribution types, and mounting specifications based on the site geometry and code requirements, then produce the formal lighting schedule for construction documents.

Yes. We design control strategies for energy code compliance (ASHRAE 90.1, IECC, Title 24), specify the hardware, and commission the installed system. We work with Lutron Vive, Acuity nLight, 0-10V, DALI, and other platforms.

Yes. Our permit coordination service includes filling out the permit application, assembling the submittal package, and communicating directly with plan reviewers to resolve comments and keep the approval moving.

Absolutely. The photometric plan remains our core deliverable and the starting point for most engagements. Additional documentation — load calculations, COMcheck, voltage drop, controls — is scoped only when the project requires it.

Yes. We design for and commission Lutron Vive, Acuity nLight, 0-10V, DALI, and DMX systems. Our controls services are available for all manufacturers, including systems not originally specified by our team.

Photometric design — also called photometric analysis or photometric calculation — is the engineering work: modeling fixtures and computing light levels across the site. The photometric plan is the permit-ready document that packages that work for plan review. Our photometric services cover the full scope: exterior and interior lighting design and layout, the photometric calculations, and the permit-ready plan — plus load calculations, energy compliance, and controls when the project requires them.
