LED Frequently Asked Questions

Commercial Indoor & Outdoor LED Lighting FAQs

What is commercial LED lighting?

Commercial LED lighting includes fixtures designed for offices, retail, schools, and building exteriors with higher performance and durability than residential products.

How much can commercial LEDs reduce energy use?

Many facilities cut lighting energy 40-75% depending on what they’re replacing.

What fixtures are most common in commercial buildings?

Troffers, flat panels, linear fixtures, downlights, and canopy lights are common.

What fixtures are most common outdoors for commercial sites?

Wall packs, flood lights, and pole-mounted area/shoebox lights are the go-to options.

What color temperature is best for commercial spaces?

4000K is a common “neutral” choice; 5000K is used when maximum visibility is the goal.

What CRI is good for commercial lighting?

70-80 CRI works for most; retail and color-critical spaces often use 80-90+ CRI.

How do I choose lumens for a commercial space?

Start with target foot-candles, mounting height, and spacing, then confirm with a lighting plan.

Do commercial LEDs work with sensors?

Yes, LEDs pair well with occupancy and motion sensors.

Are commercial LEDs dimmable?

Many are, often via 0-10V or control systems, confirm on the spec sheet.

What’s the difference between 0-10V and line-voltage dimming?

0-10V is common in commercial systems; line-voltage dimming is more common in residential-style installs.

What voltage do commercial LEDs use?

Most are 120-277V; some are 277-480V for higher-voltage sites.

Do I need 277-480V fixtures?

Only if your site uses those voltages or you’re standardizing on higher-voltage circuits.

What is a photometric lighting plan?

A layout that predicts foot-candles and uniformity before you buy and install.

What is glare and how do I reduce it?

Glare is uncomfortable brightness; optics, mounting height, and proper distribution reduce it.

Do LEDs work for parking lots?

Yes, shoebox/area lights are built for uniform site lighting and perimeter safety.

What is BUG rating?

A metric for Backlight, Uplight, and Glare that helps control spill light outdoors.

What is a cutoff fixture?

A fixture designed to minimize uplight and glare, improving comfort and reducing spill.

Do outdoor LEDs attract fewer insects?

Warmer CCT options typically attract fewer insects than higher-CCT lighting.

What is DLC and why does it matter?

DLC listing often supports utility rebate eligibility and performance transparency.

What UL rating should commercial fixtures have?

UL or equivalent safety listing is a standard expectation for commercial installs.

What warranty should commercial LEDs include?

A 5-year warranty is common; premium projects may target longer coverage.

What causes LED fixtures to fail early?

Heat, poor drivers, moisture intrusion, and wrong application fit are common causes.
