The kind of light source used distinguishes shoebox lights and floodlights from one another. High-intensity discharge (HID) bulbs, which provide a warm white light, are often used in shoebox lights. Examples of these lamps are metal halide and high-pressure sodium lamps. In contrast, floodlights employ light-emitting diodes (LEDs), which consume less energy and provide a whiter, brighter light than HID lamps.
