Commercial Lighting Buyer's Guide

Explore commercial lighting fixture types, controls, specifications, applications, and industry best practices used across commercial, industrial, and exterior lighting projects.

Understanding Commercial Lighting

Commercial lighting is designed to provide safe, efficient, and reliable illumination for workplaces, public facilities, retail environments, industrial operations, and outdoor spaces. Unlike residential lighting, commercial lighting systems are engineered to meet performance requirements for light output, operating hours, energy efficiency, code compliance, and long-term maintenance.

Modern commercial lighting systems utilize LED technology to reduce energy consumption, improve lighting quality, and lower maintenance costs compared to fluorescent, metal halide, high-pressure sodium, and incandescent lighting systems.

Commercial lighting products are commonly used in warehouses, manufacturing facilities, offices, schools, healthcare facilities, parking lots, parking garages, retail stores, hospitality venues, municipal properties, and building exteriors.

Commercial Lighting Specifications

Commercial lighting products are selected using performance specifications that define light output, efficiency, durability, compatibility, and compliance. Understanding these terms helps compare fixtures, lamps, controls, and emergency lighting equipment across different applications.

Wattage

Wattage measures the amount of electrical power a lighting product consumes. Lower wattage does not always mean lower light output, especially when comparing LED products to older fluorescent, HID, or incandescent systems.

Lumens

Lumens measure visible light output. Commercial lighting projects should be selected by required lumen output, not wattage alone.

Efficacy

Efficacy measures how efficiently a lighting product converts power into visible light, usually expressed as lumens per watt.

CCT

Correlated color temperature describes the appearance of white light, commonly ranging from warm white to neutral white to cool white.

CRI

Color Rendering Index measures how accurately a light source reveals colors compared to a reference light source.

Voltage

Commercial lighting products may support 120V, 120–277V, 277V, 347V, 480V, or other voltage ranges depending on the application.

Dimming

Dimming compatibility determines how a fixture or lamp can be controlled. Common systems include 0–10V dimming, TRIAC dimming, ELV dimming, and control-ready LED drivers.

IP Ratings

IP ratings describe protection against dust and moisture. Higher ratings are commonly used for outdoor, washdown, industrial, and wet location applications.

NEMA Ratings

NEMA ratings classify electrical enclosure protection for indoor, outdoor, wet, dusty, or corrosive environments.

DLC

DLC listed products meet performance criteria commonly used by utility rebate programs for commercial LED lighting.

UL Listings

UL listings indicate that a product has been evaluated for applicable safety standards. UL listed lighting products are commonly required for commercial installations.

NSF

NSF rated lighting products are designed for food processing, washdown, commercial kitchen, and sanitation-sensitive environments.

IK Ratings

IK ratings describe impact resistance and are useful for vandal-resistant, industrial, public, and high-abuse lighting applications.

Light Distribution Explained

Light distribution describes how a fixture spreads light across an area. Distribution type is especially important for area lights, roadway lights, wall packs, flood lights, and site lighting projects.

Type I

Type I distribution produces a long, narrow pattern commonly used for walkways, pathways, and narrow roadways.

Type II

Type II distribution is used for wider walkways, small parking areas, perimeter roads, and narrow site lighting applications.

Type III

Type III distribution projects light farther forward and is commonly used for parking lots, roadways, and general area lighting.

Type IV

Type IV distribution pushes light forward from the mounting location and is commonly used along building perimeters and parking lot edges.

Type V

Type V distribution provides a broad, symmetrical pattern used for open parking lots, intersections, large outdoor areas, and center-mounted poles.

Mounting Types

Mounting type affects fixture placement, light distribution, installation method, and compatibility with poles, walls, ceilings, brackets, and junction boxes.

Pole Mount: Used for area lights, parking lot lights, roadway lights, and site lighting.
Slipfitter Mount: Adjustable mount commonly used with tenons on poles or brackets.
Trunnion Mount: Adjustable heavy-duty mount commonly used for flood lights and area lighting.
Knuckle Mount: Adjustable mount used for smaller flood lights and landscape lighting.

Commercial Lighting Rebates & Energy Savings

Commercial lighting rebates and energy savings guide illustrating DLC-qualified lighting, utility rebate programs, LED return on investment, reduced maintenance costs, and long-term energy savings for commercial facilities.

Commercial LED lighting upgrades can reduce energy usage, lower maintenance costs, and qualify for utility rebate programs when eligible products and applications meet program requirements.

DLC

DLC qualification is commonly used by utility rebate programs to verify LED product performance for commercial and industrial applications.

Utility Rebates

Utility rebate programs vary by location, product category, efficiency level, and installation type.

LED ROI

Return on investment is typically based on energy savings, operating hours, utility rates, product cost, installation cost, and available rebates.

Maintenance Savings

LED lighting can reduce maintenance costs by lowering replacement frequency, service labor, lift rental needs, and downtime compared to legacy lighting systems.

How to Choose Commercial Lighting

Selecting commercial lighting depends on the space, mounting conditions, required light levels, electrical system, environment, controls, and long-term maintenance goals.

Indoor Projects

Indoor lighting projects should consider ceiling height, task requirements, glare control, fixture spacing, occupant comfort, and control compatibility.

Outdoor Projects

Outdoor lighting projects should consider mounting height, light distribution, weather rating, pole spacing, glare control, security needs, and local code requirements.

Retrofit Projects

Retrofit projects require matching new LED products to existing fixtures, voltage, mounting conditions, controls, and desired light output.

New Construction

New construction projects allow lighting to be selected around building plans, energy codes, fixture layouts, controls, and long-term facility requirements.
