Equivalent wattage compares the brightness of different types of light bulbs. It is a metric that indicates the wattage of an incandescent bulb that produces a similar level of brightness as the bulb being compared.
A T5 light (T5 fluorescent light) is a type of lighting fixture, particularly used in the context of growing plants. The “T” in “T5” refers to the shape of the bulb, which is tubular, while the “5” indicates the diameter of the light socket, measuring ⅝ of an inch.
Metal Halide (MH) is a type of high-intensity discharge (HID) lamp commonly used in the lighting industry, particularly in indoor gardening applications.
A circline lamp is a type of light bulb that features a circular shape, commonly used in various lighting fixtures. These lamps are particularly popular in home lighting applications due to their compact size and long lifespan.
Light reflection is the phenomenon where light waves encounter a surface or boundary that does not absorb the energy of the radiation and bounces the waves away from the surface.
Luminous Flux, also known as luminous power, is a fundamental concept in the lighting industry that quantifies the perceived power of light.
A vandal-resistant fixture, also known as a tamper-proof fixture, is a type of lighting fixture specifically designed to withstand vandalism and physical damage.
Mounting height is the vertical distance from a reference plane (such as the floor or work plane) to a luminaire or the plane of the ceiling for recessed luminaires.
High-efficiency plasma (Hep) is a class of plasma lamps that exhibit exceptional energy efficiency. These lamps have system efficiencies of 90 lumens per watt or more, making them highly efficient light sources for outdoor, commercial, and industrial lighting applications.
A halogen lamp, also known as a tungsten-halogen lamp, is a type of incandescent lamp. It is characterized by a quartz bulb and a gas filling that includes a halogen element, such as iodine or bromine.
