LED Retrofit and Lighting Assessments
LED Retrofit and Lighting Assessments
Data-Driven Lighting Upgrades
Before replacing a single fixture, E3 performs comprehensive, data-driven assessments of your facility’s current lighting infrastructure. Many facilities suffer from over-lighting (which wastes energy) or under-lighting (which creates safety concerns), as well as outdated technology that requires constant maintenance.
Our LED Retrofit and Lighting Assessment services provide you with a detailed, objective roadmap showing exactly where energy is being wasted, how much you can save, and how to fund the project using guaranteed savings or grants.
What is Included in an E3 Lighting Assessment?
1. Detailed Facility Lighting Audit Our field auditors walk every room, corridor, exterior pathway, and parking lot in your facility network, cataloging:
- Fixture types (e.g., T12, T8, metal halide, HPS) and ballast types.
- Existing electrical wattages and operating schedules.
- Current light levels (measured in foot-candles) at working plane heights.
- Mounting heights and access requirements (to identify future maintenance ease).
2. Custom Photometric Modeling Using industry-standard lighting design software, E3’s engineers create 3D photometric models of your key facilities. We simulate the new LED layout to ensure that:
- Light levels meet IES (Illuminating Engineering Society) standards for each space type.
- Illumination is uniform, eliminating shadows and hot spots.
- We optimize fixture counts, often reducing the overall number of fixtures needed while actually improving light quality.
3. Comprehensive Business Case Analysis (BCA) We compile our findings into a transparent, board-ready financial report:
- Existing vs. Proposed Wattage Comparison
Detailing the raw energy savings. - Annual Energy and Maintenance Savings Estimates
Based on your current utility tariffs and historical maintenance costs. - Simple Payback and Return on Investment (ROI) Calculations.
- CO2 Emissions Reduction Estimates
Quantifying the environmental impact of your retrofit.
4. Utility Rebate and Incentive Tracking E3 coordinates directly with Texas utility providers (Oncor, CenterPoint Energy, AEP Texas, TNMP) to identify and secure all available commercial lighting rebates. We handle the paperwork, inspections, and verification processes, applying the rebates to lower your net project costs.
Turnkey Retrofit Execution
As a true Design-Build firm, once the audit is approved, E3 executes the entire project:
- Material Procurement
Direct-sourcing fixtures from top-tier, DLC (DesignLights Consortium) approved manufacturers to ensure maximum quality and warranty backing. - Professional Installation
Handled by our experienced, certified electrical partners during off-hours (nights and weekends) to avoid daytime operational disruptions. - Responsible Disposal
Recycling old fluorescent lamps and ballasts in accordance with environmental regulations. - No Change Orders Guarantee
The project cost presented in our final agreement is fixed, ensuring complete budget security for your board.
Frequently Asked Questions
Frequently Asked Questions
What happens during a commercial lighting assessment?
During a lighting assessment, E3’s auditors conduct a comprehensive walkthrough of your facility. We inventory existing fixture types, measure current foot-candle levels, log energy usage, and identify areas where lighting is inefficient or inadequate for safety and productivity.
What is the difference between a lamp swap and a full fixture replacement?
A lamp swap (Type A retrofit) simply replaces the bulb and uses the existing ballast, which has the lowest upfront cost but leaves old ballasts that will eventually fail. A full fixture replacement (Type C) replaces the entire unit, providing the best long-term performance, longest lifespan, and the ability to integrate advanced smart controls.
How much energy can an LED retrofit save?
By upgrading legacy fluorescent, high-pressure sodium, or metal halide fixtures to high-efficiency LEDs, commercial facilities typically reduce their lighting energy consumption by 40% to 75%. Adding smart controls can push those savings even higher.
Will a lighting retrofit disrupt our daily operations?
No. E3 specializes in “ghost installations” for schools, hospitals, and busy commercial spaces. Our certified electrical crews work during off-hours, nights, and weekends to ensure the retrofit is completed with zero disruption to your daytime operations.
