LED Lighting That Pays for Itself
Most Long Island businesses are still running outdated HID, fluorescent, or metal halide lighting. Every month those old fixtures stay in place, you're overpaying on your electric bill.
IllumiGEN designs and installs commercial LED retrofits for parking lots, warehouses, offices, retail spaces, and outdoor areas. LED lighting uses 40–75% less energy than traditional fixtures and lasts 3–5 times longer, meaning lower utility bills and almost no maintenance costs.
We also install lighting control systems (occupancy sensors, daylight harvesting, and programmable schedules) to further reduce energy use. PSEG Long Island's Commercial Efficiency Program offers rebates on qualifying LED upgrades and lighting controls. We handle the rebate application as part of your project.
-
PSEG Long Island offers several commercial rebate programs. The Commercial Efficiency Program provides rebates on LED lighting upgrades, lighting controls, HVAC systems, motors, and other energy-efficient equipment. The EV Make Ready Program covers 50–90% of infrastructure costs for Level 2 and DC fast charging stations. And PSEG offers free energy audits and consultations for qualifying businesses. IllumiGEN handles all rebate applications as part of your project.
UCSUSA research shows that battery electric cars that charge off the gas-dominated grid still produce less pollution than their gas-powered counterparts, while BEVs powered by renewable energy sources are virtually emission free.
-
Most businesses save 40–75% on lighting-related energy costs after an LED retrofit. The exact savings depend on your current fixtures, operating hours, and electricity rate. For a typical commercial property on Long Island, that translates to thousands of dollars per year in lower utility bills — and the project often pays for itself within 2–3 years, even faster with PSEG rebates.
-
Yes. We install Level 2 and DC fast charging stations for all types of commercial properties — offices, apartment complexes, HOAs, retail centers, hotels, restaurants, parking garages, and more. We are a ChargePoint Certified Installer and Qmerit Certified Partner. We also coordinate with PSEG Long Island on commercial Make Ready incentives and handle all permitting across Nassau and Suffolk Counties.

A battery storage system like the Generac PWRcell works alongside your generator to give your business two layers of protection. The battery activates instantly during short outages or demand spikes — no fuel, no noise, no emissions. For longer outages, your generator takes over. Together, they also help reduce peak demand charges on your electric bill, which can be one of the largest line items for commercial properties on Long Island.
Good to Know
-
One of our electricians visits your facility, reviews your electrical panels, lighting, HVAC systems, and current utility bills. We identify where you're losing energy and put together a plan with specific upgrade recommendations, estimated savings, available rebates, and financing options. The audit is free for qualifying PSEG Long Island commercial customers.

It depends on the scope. A straightforward LED retrofit for a small office can be completed in 1–2 days. A multi-station commercial EV charger installation typically takes 1–3 weeks including permitting. Battery storage installations usually take 2–5 days. For larger combined projects, we create a phased schedule so your business stays operational throughout. We provide a clear timeline during your free consultation.
