What this accessory isThe
ZZHUPCR90240SS is a
90 degree PC reflector made by
SPECLITE for the HU90CBF4240MDSS
UFO high bay. It is an optical accessory, not a light source: it mounts to the luminaire and redirects the output into a narrower, more controlled distribution. Contractors reach for a reflector like this when a bare
LED high bay light throws too much light sideways — into windows, onto mezzanine walls, or into the eyes of a forklift operator — instead of onto the floor and the racking where the work actually happens.
Construction and light qualityThe reflector body is polycarbonate (PC), a material chosen in industrial lighting because it is impact-tolerant and light in weight, so it does not stress the hook, chain or pendant holding the fixture. Optically, the job of the 90 degree profile is simple and effective: capture the wide-spreading light at the edges of the beam and push it down. The practical result on site is a brighter, more even pool of light directly under each fixture, less glare at eye level, and better vertical illumination on tall shelving faces. Because it is a passive optic, it does not change the electrical behaviour of the luminaire in any way — the driver, the sensor and the dimming function of your high bay keep working exactly as before.
Installation and compatibilityInstallation is mechanical only. No wiring, no additional driver, no power connection and no tools beyond what you already use to hang the fixture. Keep the reflector clean during handling, fit it to the luminaire before hoisting the high bay to its final height, and you are done. Compatibility is strict and deliberate: this reflector is designed for the
UFO Highbay V2 240-200-150W, 120-347V, black housing with clear lens, motion sensor and 0-10V dimming. Do not assume it fits other
round high bay LED lights or other series — if the fixture is not the HU90CBF4240MDSS, this is not the reflector for it.
Where it pays offThink of any space where the ceiling is high and the target is the floor. In a distribution warehouse with narrow aisles, reflectors keep light in the aisle instead of washing the top of the racks. In a truck or mechanical garage, they put usable light on the bay floor and under the hoist. In a manufacturing plant, they sharpen the contrast on assembly benches and CNC stations. Arenas, curling clubs, agricultural barns, salt sheds and municipal garages benefit for the same reason, and so do oversized residential garages and hobby workshops where a single
LED high bay has to cover a big footprint. Order one reflector per fixture so the whole installation reads the same way from aisle to aisle.
DocumentationThe technical PDF spec sheet for the
ZZHUPCR90240SS is available in the Documentation tab of this page, alongside the identification of the luminaire it serves. Keep it with your submittal package so the reviewing engineer, the electrician and the building owner all see that the beam control was specified on purpose — and so the right reflectors are reordered when the building expands.
