Commercial Lighting & LED Retrofits in Longmont
Longmont’s building stock leans industrial. That usually means high ceilings, older high bay fixtures, and long run hours, which is where lighting projects pay back fastest.
Quick answers
Lighting Questions People Ask First
Are lighting rebates available in Longmont?
Eligible Longmont Power & Communications business customers may have access to lighting rebates through Efficiency Works.
What gets upgraded
Lighting Work in Longmont
Manufacturing Lighting
Production floors need steady light levels across shifts.
LED high bay fixtures hold output better than metal halide as they age, and they restart instantly after a power dip.
Industrial and Warehouse Lighting
Tall spaces with few controls are the most common savings case in Longmont.
Aisle sensors and zone control let unused areas sit at a low light level.
Office and Technology Buildings
Office areas inside industrial buildings often still use older troffers.
Lab and equipment rooms may need specific light levels, so check the space before choosing a fixture.
Retail and Grocery Lighting
Grocery lighting runs long hours and sits next to refrigeration, so both loads matter.
Case lighting and ceiling lighting are usually handled as separate measures.
High Bay and Fluorescent Replacement
Metal halide high bays draw high wattage and take time to restrike.
Fluorescent strip fixtures are usually replaced or retrofit with LED tubes or new lamp assemblies.
Lighting Controls
Sensors, scheduling, and dimming cut the hours a fixture runs at full output.
In two shift buildings, controls often matter more than fixture wattage.
Energy and Upkeep Savings
Energy savings show up on the monthly bill. Maintenance savings show up in fewer lamp changes and less lift work.
Both belong in the payback math.
