a better solution. Because the Provincial Government incentivizes businesses with rebates to outfit their facilities with sustainable lighting solutions, Tim knew efficiency would be a top criterion. In order to increase workplace comfort

and ultimately productivity, Sunwest needed LED fixtures and lighting controls that made minimal noise.

Why Digital Lumens?With those objectives in mind, Digital Lumens

was the clear choice to retrofit solutions for the

51,200 ft2 Sunwest facility thanks to its intelligent

LED fixtures. DLE intelligent LED high-bay

fixtures, provide superior efficiency and control

in the most demanding customer environments

and are also a high-performance alternative to

the uncontrolled LED, fluorescent, and HID high-

bay fixtures. DLE fixtures are incredibly flexible

thanks to:

• Lumen output from 12,521 to 54,830lm

• Narrow, Wide, Aisle, and Diffuse optic options

• Rotatable light bars and direct/indirect lighting

Distribution options for uniform lighting across

both ceilings and workspaces

Every Digital Lumens fixture, including the DLE,

contains embedded sensors which work in

tandem with advanced software applications

to instrument facilities for the Industrial IoT and

provide value beyond illumination. SiteWorx

Tune, Digital Lumens’ IIoT lighting control

application, uses smart sensors and advanced,

cloud-based software to maximize energy

savings, improve productivity, and maintain

safe, comfortable light levels.

The ResultsThrough the combination of DLE intelligent LED fixtures, and SiteWorx Tune, Tim was able to implement

advanced lighting strategies such as task tuning and progressive dimming to drive a drastic reduction

in lighting energy usage and spend. The company saved 86% on their lighting energy costs and are

on track to save 45,286 kilowatt hours (kWh) annually. Sunwest Aviation can now illuminate specific

areas within each hangar, like the main walkways, only when there is activity, instead of choosing

between shutting the lights off completely or running them continuously. Energy use verification and

robust reporting functionality also allow Sunwest Aviation to effectively monitor real-time electricity

usage and compare it with historical data points to identify trends, anomalies, and opportunities for

further savings.

Those up-to-the-minute reporting capabilities help Tim to easily provide accurate, real-time, and

historical updates to his CEO and CFO. With the extremely quiet DLE fixtures, productivity and

employee comfort has improved, as team members no longer experience headaches from light

fixtures sounds and can more easily communicate with each other across the hangar. Thanks to

the significant increase in energy savings, and a positive response by employees to the quieter

workspace, Sunwest plans to retrofit the rest of their hangars — another 51,200 ft2 — with DLE

fixtures and SiteWorx Tune.
