Lighting designer and electrical contractor reviewing photometric plans

Specification services

Acuity Brands support from lighting intent to closeout

Commercial projects rarely fail because a fixture name is missing. Friction appears where distributions, ceiling conditions, driver interfaces, controls sequences and delivery dates do not line up. Our service path gives each decision a defined input, review point and handoff.

Three disciplines around one project record

01

Application review

We translate room use, mounting height, target illuminance and visual comfort objectives into a shortlist. The review notes where high efficacy may conflict with UGR, CRI or beam control rather than hiding that trade-off.

02

System coordination

Driver type, dimming range, emergency provision, occupancy sensing and daylight harvesting are checked against the controls narrative. DALI-2 and 0-10V options are treated as different commissioning paths, not interchangeable labels.

03

Submittal support

Product data, IES or LDT files, applicable UL or CE information and sample status are organized for design review. Final availability and local certification scope remain subject to selected catalog numbers and destination.

A five-gate project sequence

  1. 01 — Define.

    Record application, ceiling type, voltage, controls protocol and required milestones.

  2. 02 — Model.

    Use photometric files under stated reflectance, maintenance and mounting assumptions.

  3. 03 — Sample.

    Review finish, source appearance, glare and control response in the intended context.

  4. 04 — Release.

    Freeze approved configuration, quantities, ship-to sequence and substitution rules.

  5. 05 — Handover.

    Close gaps in labeling, commissioning notes, warranty contacts and replacement planning.

Clear gates reduce avoidable substitutions

Quoted performance depends on the final optical package, input voltage, ambient temperature and control configuration. Photometric calculations are design evidence, not a guarantee of field illuminance where surface reflectance, furniture or installation geometry changes.

Start with the project variables that matter

Attach a fixture schedule or describe one representative room. We will identify the missing selection inputs before proposing the next review.
