Commercial LED Lighting Retrofits in Denver
LED conversions and lighting controls for warehouses, offices, parking garages, and retail space.
A retrofit starts with a fixture count and a light reading. Existing fixture type, lamp count, mounting height, and measured foot-candles decide whether a retrofit kit inside the existing housing makes sense or whether full fixture replacement is the better path, and aged housings, yellowed lenses, or a changed room layout usually argue for replacement. Driver and dimming compatibility matter as much as the light source, since a ballast-bypass lamp means rewiring the sockets and labeling the fixture, and older dimming systems do not always talk to new drivers.
Controls are where most of the code lands. Commercial spaces are generally expected to have automatic shutoff, occupancy or vacancy sensing in many space types, and daylight-responsive control near windows and skylights, and older buildings often have no control wiring in the ceiling at all, which points toward line-voltage sensors or wireless devices. Emergency fixtures need a second look during any retrofit, because an existing emergency ballast may not drive a new LED board and egress illumination has to survive the change. Removed lamps and ballasts leave the site as regulated waste rather than in the dumpster.
Is it better to retrofit existing fixtures or replace them with new LED fixtures?
Retrofit kits make sense when the housings are sound, the layout still works, and the light distribution is right for the space. Full replacement wins when fixtures are corroded or yellowed, mounting is being changed, or new optics and integrated controls would do a better job than a kit dropped into old housing.
What lighting controls does the energy code require in a commercial space?
Generally automatic shutoff so lights do not run all night, occupancy or vacancy sensing in many space types, separate control of daylit areas near glass, and control of exterior lighting. The specific list varies by jurisdiction, occupancy type, and the code edition in force, so the requirements get confirmed for the project before fixtures are ordered.
Do LED retrofits affect emergency and egress lighting?
They can. Fixtures with emergency battery packs use a ballast or driver matched to the light source, and swapping the source without addressing that can leave the unit unable to operate in an outage. Any retrofit in an egress path should confirm that emergency illumination still performs after the change.
