A Contractor's Guide to Spec'ing & Bidding a Lighting Job
For electricians and contractors, lighting is part of the bid and part of the reputation. Spec it right and the job is clean, profitable, and call-back free. This guide covers how to size, spec, and price a lighting package.
A solid lighting bid starts with the space and target light level, picks fixtures by mounting height and environment, confirms voltage and listings, and prices in rebates. Getting those right protects your margin and the client's satisfaction.
Spec the Right Fixtures
- Set target foot-candles for the application.
- Choose high bay or low bay by mounting height.
- Seal for the environment using IP ratings.
- Confirm voltage and safety and DLC listings.
Price It Accurately
Use the fixture calculator to nail fixture counts so you are not over or under. Factor rebates the client can claim, and lead with lifetime cost using the TCO guide. For government and federal jobs, check TAA, BAA, and BABA compliance.
Win on Service
Replaceable-tube fixtures mean fewer warranty call-backs and easy client maintenance, a selling point in your bid. See replaceable-tube vs integrated. For project volume pricing, see buying in bulk.
