Commercial LED retrofits for South Florida facilities
Avision Lighting replaces aging commercial lighting with LED systems for facilities in Palm Beach, Broward, and Miami-Dade counties. A retrofit is a design problem first: what is installed, what light level the work needs, and what controls the building will actually use.
Is an LED retrofit worth it for a warehouse?
It is worth pricing when the existing system is metal halide, fluorescent, or an early LED product that has dimmed, shifted color, or become expensive to maintain. Whether it is worth doing depends on fixture count, hours of operation, mounting height, and the shape of the space — not on a generic savings percentage. Avision does not publish a universal energy-savings claim.
Warehouses that run long shifts usually feel the maintenance difference first: fewer lamp changes at height. Energy use can drop when high-wattage HID fixtures are replaced with LED at a comparable light level, but the number is a calculation from the existing wattage, the proposed wattage, and the operating schedule. Without those inputs, a percentage is a guess.
A short evaluation starts with photos of a typical bay, the lamp or fixture wattage printed on a nameplate, a rough count, and the ceiling height.
Can existing high-bay fixtures be replaced with LED?
Yes. High-bay LED fixtures are a standard replacement for HID high bays when the structure can carry the new fixture and the circuit can feed it. The mounting point can often be reused. The optical distribution usually should not be copied blindly, because an LED high bay throws light differently than the reflector it replaces.
Spacing, aisle width, and rack height decide the photometrics. A one-for-one swap that ignores the racking layout can leave the top of a pick face bright and the floor dark, or the reverse. That is why a retrofit design includes a layout, not only a model number.
How is a commercial lighting retrofit designed?
Avision designs a retrofit in a fixed order: audit the existing fixtures, count them, record wattage, assess light levels against the task, select replacements, check photometrics and controls, install, then commission. The output is a scope a facility manager or general contractor can build from, not a catalog page.
Existing fixture audit means type, mounting height, condition, and whether the housing stays. Fixture count and wattage are the basis for any later energy comparison. Light-level assessment is what the task needs — storage, packing, inspection, retail floor — not a single number for every building.
Replacement design covers distribution, color temperature, glare, and controls. Photometric considerations include spacing and obstructions. Controls may be as simple as zoning and occupancy sensing, or as involved as daylight response. Installation and commissioning confirm aiming, controls, and that the scenes staff were promised actually recall.
What information is needed before recommending replacement fixtures?
The useful packet is a fixture count, the existing wattage from a nameplate or lamp type, mounting height, photos down a typical aisle or bay, the hours the lights run, and what the space is used for. A floor plan or reflected ceiling plan makes the recommendation specific. Without a count and a height, fixture selection is still a guess.
Voltage, emergency-lighting requirements, and whether controls must tie into an existing building system also change the specification. Those details are part of the evaluation, not assumptions.
How are light levels determined?
Light levels are determined from the task and the geometry of the room, then checked with a photometric layout. There is no single foot-candle target for every commercial building. Bulk storage, fine assembly, a retail aisle, and a sports court are different problems, and South Florida daylight at a loading door changes the picture again.
A photometric study is a calculation of how the selected fixtures, at a stated mounting height and spacing, deliver light to the work plane. It is not a photograph and it is not a savings estimate. Avision explains the method in project conversations; this site does not yet include a completed photometric report from a named facility.
