LED shoeboxes are an efficient, modern way to replace metal halide and high pressure sodium (HPS) lamps for outdoor applications. LED shoeboxes are great for lighting areas like parking lots, outdoor walkways and public parks. Browse our products below or scroll down to read more about how to find the right shoebox.
LED Shoebox Mounting Options
A direct mount allows you to attach your shoebox directly to an existing pole. That means direct mounts are the easiest way to switch over your existing HPS or metal halide lights to LED.
Installation will involve wiring your light and then attaching the shoebox to the pole using bolts. That simplicity is a major advantage of direct mounts, but it’s important to know that they’re also generally short and designed to be installed in one particular orientation . That means they don’t provide the flexibility of some other mounts.
As their name implies, slip fitters slip on top of a pole rather than being bolted onto the side (like a direct mount). Wiring feeds all the way up the pole, through the mount, and into the back of the lamp.
The main advantage of slip fitters is that they are generally hinged, allowing the lamp to be tilted, pitched, and adjusted.
Slip fitter mounts are ideal for situations in which you’re trying to focus light in a particular area or working in a challenging space.
A trunnion mount is a hinged, square frame made of thin metal. Wiring a trunnion mounted LED shoebox involves threading insulated wires through that frame and into the back of the lamp.
Trunnion mounts are highly versatile and can help you fit powerful lamps into tight spots and direct your beam in a directional manner to achieve lighting goals.
Unlike direct or slip fit mounts, trunnions do expose some wiring to the elements, so they do require some increased maintenance.
Light Distribution Patterns for LED Shoeboxes
Not all lamps achieve the same lighting effects. That’s additional true for LED lamps, which are directional in nature.
Type I LEDs create a long, narrow, flying saucer shaped light pattern. These are most commonly used for walking paths, sidewalks, bike trails, and other narrower areas.
Type II LEDs cast a long oval of light that’s ideal for alleys and smaller roads. Positioned over the edge of a narrow road, a Type II LED can illuminate the entire width of the road and both shoulders.
Type III lamps create a shorter, wider, more circular oval of light than their Type II counterparts. They are frequently used in parking lots or to create more light on the edges and shoulders of a road.
Unlike Types I, II, and III, Type IV LEDs do not create a symmetrical field of light. Instead, they create a semicircle, reaching far in front and to the sides of the lamp while providing almost no light behind. Type IVs are useful for bringing additional light to a particular side of a road, public space, or parking area.
Type V LEDs provide an omnidirectional circle of light. The radius of that circle is far tighter than the reach of any of the previously mentioned types, but within that circular area, the light is bright and clear. Type V LEDs are great for use in the middle of parking lots or at intersections.
Type VI LEDs (sometimes called “Type VS”) create an omnidirectional square of light. This creates a highly symmetrical field with near equal foot candles in almost every part of the field. Like Type Vs, Type VI LEDs are excellent at areas where traffic comes together (like on ramps, intersections, etc.) as well as large parking lots.
LED Shoebox Features to Consider
The IP (Ingress Protection) rating of your shoeboxes will determine just how tough and durable they are.
IP ratings are two digit numbers: the first digit represents the fixture’s ability to protect your lamps from dust on a scale of 0 – 6 (with 6 being the best). The second digit represents protection from moisture on 1 – 8 scale (with 8 being the best).
Since dust (from cars, the roadway, exhaust, etc.) and moisture (from rain, snow, cleaning, etc.) both have the potential to affect outdoor lights, you need to shop with IP rating in mind.
Generally, a 65 (completely dust tight and protected against jets of water like from a power washer) is an ideal IP rating for an LED shoebox.
Photocell sensors, also known as “dusk to dawn sensors,” help exterior LED lights shine only when an as much as is needed. That can lead to up to a 50% energy savings per lamp for you!
If you’re switching your HPS or metal halide lamps over to LED to take advantage of the increased efficiency, you’ll definitely want to make sure they have dusk to dawn sensors installed to maximize your returns.
Dimmability is another one of the features that make LED lamps so attractive, efficient, and inexpensive over the long term. Not all LED shoeboxes are necessarily dimmable, though, so when you’re shopping, be sure to look out for products clearly marked “Dimmable.”

It can be difficult to understand your lighting needs without a photometric analysis in place. A photometric analysis will help you understand the unique lighting needs of your space and tell you exactly how many and what kind of lamps you need to achieve your goals.
