One housing, nine wattages: 60W to 400W

The shoebox range is deliberately a single platform. The same aluminium body and 80x150° optic carry 60W through 400W, so a car park can be lit at 60W at the entrance and 200W over the main drive without two different fixture families on site. Output scales linearly to 300W at 130 lm/W; the 400W model runs at 150 lm/W and adds a Type III distribution for roadway and drive-aisle layouts.

The 80x150° optic is the reason shoeboxes look the way they do: a wide horizontal spread with a narrow vertical throw, mounted on a slip fitter at the top of a pole and aimed across the lot rather than straight down. It is the correct distribution for a parking bay grid, and the wrong one for lighting a facade, which is a flood light job.

Output and efficacy are the published datasheet values. The replacement column is a lumen-equivalence guide at 65 lm/W for the old HID system; confirm against the existing fixture count before ordering.

Pole height, spacing and coverage

A shoebox layout is defined by the pole grid, and the grid is set by the illuminance target. For a general parking area the usual target is 15 lux average with a 4:1 uniformity ratio; for a dealership display lot it is 30 lux, and for a tennis court or sports apron it is 100 lux or more, which is where the 300W and 400W models come in.

The table uses area = lumens x 0.56 ÷ 15 lux with a utilisation factor of 0.7 and a light-loss factor of 0.8. A single 200W fixture on a 10 m pole covers about 970 m² on paper, which is a 31 x 31 m area — in practice poles sit 25-30 m apart and overlap so the uniformity holds at the edges, not just under the fixture.

* CU 0.7 and LLF 0.8 at 15 lux on the ground. For 30 lux halve the area, for 10 lux increase it by half. Pole spacing assumes overlapping cones for uniformity; send the lot drawing for a DIALux layout.

Replacing metal halide parking lot lights

Most shoebox retrofits replace a 250W to 1000W metal halide or HPS area light on an existing pole. Because the shoebox mounts on the same pole arm, the pole, the base and the wiring usually stay; only the head and the photocell change. Matching the old lumens rather than the old wattage is what keeps the lot at the same brightness — a 400W metal halide system delivers roughly 26,000 lm, which is exactly the 200W shoebox.

* Compares LED wattage with lamp plus ballast wattage at 65 lm/W system efficiency.

Photocell, motion sensor and dimming

Shoeboxes are usually the first fixture on a site to get controls, because a car park runs 12 hours a day and half of that is empty. Three options are available on this range: an integral photocell for dusk-to-dawn switching, a microwave motion sensor that drops the fixture to a low hold level when nobody is in the aisle, and 0-10V dimming for a central lighting control system or a utility demand-response programme.

Order the control with the fixture rather than retrofitting it: the sensor is factory-fitted into the housing and the dimming leads are brought out to the terminal block, so a site electrician connects three wires instead of opening a sealed luminaire.

Housing, sealing and certification

The body is die-cast aluminium with a polycarbonate lens, finished for outdoor exposure; the 80x150° optic is moulded into the lens rather than added as a separate reflector, which is why the IP65 seal holds after a pole-top installation. Operating temperature is rated -40 to +40°C, and the driver is mounted in the housing away from the LED board to keep the case temperature down in hot climates.

Mounting bracket is supplied with the fixture; arm, yoke and tenon adaptors are quoted per project against the existing pole. الشهاداتs on the certificate page.
