Commercial Lighting Services are essential to a productive and safe environment. Whether it is for employees, customers, or personal use. Furthermore, as the lighting industry changes, so too does the terminology. Thus, we are going to take a basic look at lighting terminology. As an example, this will better explain the different solutions and services available when partnering with Action Services Group as your commercial lighting services provider.

First, a lamp is an equipment that produces light from electricity. Second, it is the more common term for a light bulb. Third, it houses the fuel and ignition system of the light.
A light fixture or light fitting is a device that contains an electric lamp that provides illumination.
A ballast is a device used for limiting the current in a lamp. Consequently, a ballast aids in the initial voltage build-up for starting a fluorescent lamp. It will quickly reduce the voltage and regulate the current to produce a steady light output.
High-intensity discharge lamps require a higher voltage to start and utilize an ignitor. The ignitor is used to build high voltage pulses to switch on the lamp. The ignitor stops pulsing once the light comes on.
Color rendering index (CRI)
A method for describing the effect of a light source on the color appearance of objects being illuminated, with a CRI of 100 representing the reference condition (and the maximum CRI possible). In general, a lower CRI indicates that some colors may appear unnatural when illuminated by a lamp.
The color temp is the description of the color appearance of a light source in terms of warmth or coolness, as measured on the Kelvin scale (K). As the temperature rises, the color appearance shifts from yellow to blue. Thus, lamps with a low CCT (3000K or less) have a yellow-white color appearance. They are a “warm” light. Lamps with a high CCT (4000K and higher) have a blue-white color appearance. They are considered “cool” lighting.
The ratio of light output (lumens) to input power (watts), expressed in lumens per watt (LPW).
The amount of light that reaches a surface. The measurement for Illuminance is in foot-candles (lumens/square foot) or lux (lumens/square meter). One foot-candle equals 10.76 lux, although for convenience the IESNA uses 10 lux as the equivalent.
The median lifespan of a vast number of lamps. Half of the lamps in a sample are likely to fail before the rated lamp life. Or half are expected to survive beyond the rated lamp life.
Lamp lumen depreciation (LLD)
The reduction in lamp light output that progressively occurs during lamp life.
The photometric quantity most closely associated with the perception of brightness, measured in units of luminous intensity (candelas) per unit area (feet squared or meters squared).
The measurement of the total light output of a light source.
The measurement of the total power output of a light source.
Watts are the measurement of power consumed by the lamp, while lumens are the measurement of the visible light output of the lamp. It is a common misconception that a higher watt lamp equals a higher light output, but don’t get confused. When calculating the brightness of a light, you need to identify the lumen output, not the wattage.
The amount of visible light falling on an object.
Foot-candles measure the amount of visible light that falls on a surface or object. A single foot-candle is equivalent to the amount of light falling on a surface or object one foot away from the lamp.
A Closer Look at Color Temperature and Color Rendering Index
First, Edison’s incandescent lamp or light bulb gave off a slightly yellowish glow measuring in at 2700K (Degrees Kelvin). Second, with the advancements in CFLs and LED lamps, we have moved farther away from the first lamps. These early lamps produced a soft white color temperature. Third, with new technologies, we have a vast range of color temperatures providing a large variety of lighting options.
Color Temperature for Commercial Lighting Services
There are three primary types of color temperature for lamps:
Soft White (2700K –3000K)
Bright White/Cool White (3500K –4100K)
Daylight (5000K –6500K)
As an example, the higher the degrees Kelvin, the whiter the color temperature. While whiter lights may appear brighter than lower kelvin readings, the number of Lumens does not change. The actual brightness is unaffected.
Color Rendering Index for Commercial Lighting Services
Depending upon your lamp’s location and the desired effect, CRI or Color Rendering Index need consideration. The CRI measures the ability of a light source to reproduce the colors of an object compared to an ideal light source, i.e., incandescent or natural light. The CRI scale runs from 0-100, with lights closer to a 100 CRI showing more accurate colors across the spectrum. While this is not going to be a primary consideration for a warehouse, retail stores should pay close attention to their lamps CRI.

The Different Types of Lamps on the Market Today
There are four basic types of lamps used on the market today. Your lamp selection should take into consideration your lighting performance needs, maintenance concerns, and energy costs. Your commercial lighting services provider should discuss these lamps with you.
Incandescent lamps remain the most common light bulb in use today. They range from 40-110 watts, usually with a warm, yellow-white light. The incandescent lamp provides a warm, inviting quality with an excellent color rendition that compliments most skin tones and is psychologically appealing. Even with the shifting trend towards LED, incandescent lamps remain the most common, mainly due to the price of the lamp. While the lamp may be inexpensive, they are not the most energy-efficient, nor do they last the longest. The average incandescent bulb lasts between 700 –1,000 hours. This may seem like a long time, but with some lamps, depending upon location, needing to stay lite for 20 –24 hours a day, other options provide a much longer lifespan.
How does the Incandescent Lamp Work?
The incandescent lamp is an electrical lighting source produced by incandescence or the emission of light caused by the heating of a filament. Typically, the incandescent lamp consists of a tungsten filament contained in a glass enclosure. There is also a stem or glass mount attached to an airtight base. Small embedded wires support the filament or lead wires. An electrical current passes through the filament which heats it to a temperature that produces light.
The halogen gives off a white light, that is the closest to natural daylight. While the halogen is more efficient than an incandescent, you must take extra care when changing out these lamps. The halogen lamp warms quickly and can cause burns to an unsuspected person or create a fire hazard in specific locations. Oil residue from the human hand can also rub off on the lamp, potentially causing the lamp to warm to quickly, which could cause the lamp to explode. Make sure you wear gloves when changing out halogen lamps.
How does the Halogen Lamp Work?
The halogen lamp is the most like the incandescent. Mainly due to both using a filament that heats to the point of glowing. The incandescent lamp evaporates the tungsten from the filament, causing blackening of the lamp. While the halogen eliminates the tungsten evaporation by reacting to the halogen gas. The halogen then returning some of the tungsten to the filament extending the life of the lamp.
The fluorescent lamp comes in two varieties, the compact fluorescent and the linear fluorescent both of which function identically. The fluorescent is a gas-discharge lamp that comes in a wide range of sizes, wattages, and colors, with long life, low cost, and high energy efficiency.
The compact fluorescent comes in a screw-in or a plug-in. The screw-in can generally be used in an existing screw socket without additional equipment while the plug-in requires a ballast and socket specific for its base configuration.
The linear or tube fluorescent is still the most widely used in commercial settings. This is mainly due to its long life, and it remains one of the least expensive options on the market. The fluorescent tube also comes in a wide variety of applications based on lamp type.
How does the Fluorescent Lamp Work?
The fluorescent lamp is a gas-discharge lamp. Using a process known as inelastic scattering, electricity emitted from cathodes excite mercury vapor contained within the glass. Also included within the glass are phosphors and a noble gas, which glow when the mercury atoms produce ultraviolet light, thus creating a visible light source.
The LED lamp stands for light-emitting diodes and is the most energy-efficient lighting option on the market today. The LED is a solid-state technology meaning the materials used to generate light are enclosed within a solid material. The heat produced by the lamp is absorbed into a heat sink, which keeps the lamp cool to the touch and saves considerable energy. Due to the solid-state of the LED, they are much less susceptible to failure caused by shock or vibrations. Another significant difference between LED and other lamps is the fact that LEDs don’t burn out. They experience lumen deprivation causing their light output to decrease. If considering a lighting upgrade for your facility, a Turn-Key LED Retrofit is the most energy-efficient lighting upgrade you can perform.
How does the LED Lamp Work?
The LED or light-emitting diode is a two-lead semiconductor that emits light when activated. The electrons recombine with electron holes once a suitable voltage is applied to the leads, releasing energy in the form of photons, causing an effect called electroluminescence, creating a visible light source.
