Commercial lighting control systems determine when lights operate, how much light they provide and which fixtures respond together. A system may serve one room or coordinate lighting across an entire building. For distributors and ESCOs quoting retrofits, the challenge is matching the controls to the installed equipment, the way each space is used and the scope the customer expects. A sensor count alone does not establish a complete project price. This guide explains the main

Switching lighting audit software is easier when you separate the information you will reuse from the records you need to retain. Your current product prices and usable fixture schedules can help you prepare the next quote. Previously issued proposals and project photos need a dependable archive. For distributors and ESCOs considering a move from Retrolux, SnapCount or spreadsheets, the practical question is how to keep quoting while establishing a reliable workflow in the ne

A California lighting retrofit can look straightforward: count the fluorescent fixtures, select LED replacements and calculate the savings. The quote gets harder when you reach the controls, wiring and paperwork. Title 24 lighting requirements depend on what you are changing and which compliance path applies. A lamp replacement, an LED retrofit kit and a complete fixture replacement can lead to different scope decisions. Before you price the job, establish five things: the ap

Local Law 97 gives New York City building owners another reason to review their lighting: electricity use contributes to the emissions counted against a building’s annual limit. Lower-wattage fixtures and better controls can reduce that electricity use while cutting operating costs. The useful question is how much of your building’s emissions gap the lighting work can close. An office with fluorescent fixtures left on after hours has a different opportunity from a building th

A Local Law 88 lighting audit needs more than a building-wide fixture count. The team reviewing the upgrade also needs to understand how each space is used, what controls are installed and which details still need verification. For distributors, ESCOs and retrofit teams, collecting that information during the first walkthrough makes the estimate easier to build and reduces follow-up visits. This checklist explains what to record, how to organize sensor information and how to

How does lighting rebate cash flow affect upfront cost? Lighting rebate cash flow depends on when the customer receives the incentive. A discount applied at purchase reduces that payment immediately. A post-project rebate leaves the customer covering the cost until payment arrives. Two projects can have the same final net cost but require different amounts of cash upfront. Gross cost, cash due and net cost: three different numbers A proposal needs to distinguish the project’s

Choosing the right route starts with understanding midstream vs prescriptive vs custom lighting incentives. A midstream discount reaches the customer through a participating distributor. Prescriptive incentives follow published measures and formulas, while custom incentives depend on project-specific savings calculations. For distributors and ESCOs, these differences affect product selection, approval requirements and how the incentive appears in the quote. This guide explain
