Types of Commercial Lighting Fixtures
American-made Commercial Lighting fixtures feature the highest commercial grade lighting fixtures in all major light sources used for building exterior, site lighting, security lighting, warehouse interior lighting, roadway lighting, and security lighting systems. Contractors and end-users benefit from a great freedom of choice when working with RLLD Commercial Lighting. As a multi-manufacturer representative, we maintain an objective stance toward brand and technology type, working through a nation wide distribution network that is quota free from our standpoint. This means that we will never insist that any company or individual buy a particular product from us to fulfill obligatory demands of our vendor status. On the contrary, we actually extend vendor privileges to our clients by allowing sole proprietor designers and electricians direct access to the relationships we enjoy with the world’s top manufactures and giving them access to pricing and shipping services that smaller companies and individuals may not be able to obtain on their own.
Clients of US distributors like RLLD Commercial lighting can thus obtain fixtures of any type, size, intensity, and design simply by contacting and RLLD lighting specialist and placing an order directly through our distribution network. Our growing inventory offers the following to contractors, end users, architects, and building developers nationwide.
Incandescent
Although incandescent lamps are more frequently used in residential lighting applications, some commercial lighting fixtures also used this technology. Incandescent lamps pass current through a filament, which causes the filament to give off light. Because they are relatively short lived, incandescents are used mostly as decorative commercial lighting fixtures. Their ability to render warm colors effectively without ballast makes them well suited to this application, and the enormous variety of bulb designs make them highly soft after source of any type of accent lighting or decorum based commercial lighting design.
Fluorescent
Fluorescent lamps are used extensively in commercial lighting fixtures for a number of reasons. First and foremost of these reasons is their ability to use less power than other commercial lighting fixtures, making them very cost effective from an energy conservation perspective. Fluorescent bulbs also produce a very bright light that is evenly distributed, making them ideal commercial warehouse lighting fixtures, canopy lights, security lights, in interior retail lights in discount stores where high levels of general lighting help psychologically motivate larger bulk purchases of discount merchandise.
Fluorescent bulbs produce light by activating phosphors on the interior of the bulb using ultraviolet energy generated by a mercury arc. Ballast helps start and operate the fluorescent lamps by regulating electron flow through the gaseous arc. Trends in fluorescent technology have made them more compact, increasing lumens per watt efficiency as high as 100 lumens per watt, and reducing the amount of toxic mercury within the bulbs interior. Fluorescent commercial lighting fixtures are best deployed underneath building eaves (as in the case of canopy lights), near loading docks, in wallpacks on the sides of buildings, or as large grocery store or warehouse lights. Placing them too far out into open spaces tends to diffuse their light output and diminish their intensity.
High Intensity Discharge (HID) Commercial Lighting Fixtures
HID stands for High Intensity Discharge. It refers to a technology where light is produced by a gaseous arc discharge using a variety of elements. Typical elements include mercury vapor, metal halide, and high pressure sodium. The arc tube within an HID lamp will contain one or more of such elements, and when current passes between the electrodes at either end of the tube, the current creates an arc that generates visible light.
HID lamps feature the highest efficiency in lumens per watt output and also feature a greater level of lighting control. They also last longer than other commercial lighting fixtures, making them a wise investment for a company on a Spartan budget that cannot afford to continually replace equipment.
High intensity discharge sources include mercury vapor, metal halide, and high pressure sodium (HPS) lamps. Light is produced in HID and low pressure sodium (LPS) sources through a gaseous arc discharge using a variety of elements. Each HID lamp consists of an arc tube which contains certain elements or mixtures of elements which, when an arc is created between the electrodes at each end, gasify and generate visible radiation.
Light Sources and Lamp Characteristics:
Mercury Vapor (MV)
Mercury vapor lights were the first HID commercial lighting fixtures developed. They were designed originally to meet a rising demand for a very compact, high output, and energy efficient source of light. They are used extensively in a number of landscape lighting applications, being commonly deployed as tree lights in high-end commercial outdoor lighting systems. In other applications they have proven somewhat less effective duo to their inferior color rendering abilities, although this has improved to a certain extent over the years by phosphor coated interior bulb walls.
The life of mercury vapor lamps is good, averaging 24,000 hours for larger wattage lamps. However, because the output diminishes so greatly over time, economical operational life is often much shorter. Efficacy ranges from 30 to 60 lumens per watt, with the higher wattages being more efficacious than the lower wattages.
As with other HID lamps, the starting of a mercury vapor lamp is not immediate. Starting time is short, though, taking 4-7 minutes to achieve maximum output depending upon the ambient temperature.
High Pressure Sodium (HPS)
High Pressure Sodium (HPS) commercial lighting fixtures gained huge popularity in the 1970’s to meet the needs of a powerful, yet super efficient, source of HID lighting. Lumens per watt output in an HPS lamp can be as high as 140 lumens per watt-approximately 7 times the luminance as incandescent lamps and twice that of MV or Fluorescent. They also last for approximately 24,000 hours—the longest lamp light on the market.
The problem with HPS commercial lighting fixtures has always been the quality of light they create. HPS lamps give off a yellowish or orange-tinted color and are not acceptable light sources for situations where illuminating a brand, architectural keynote, or any type of ornate exterior landscaping requires a high level of color rendering. For the most part, they are used in applications such as commercial parking garage lighting, warehouse lighting, and certain outdoor applications such as security flood lighting.
Metal Halide (MH)
Metal Halide (MH) commercial lighting fixtures are fast becoming the preferred source of HID lighting in most commercial environments. This is because they produce a very bright white light that nearly equivalent to daylight in its color rendering ability. The variety of applications is significant as a result, ranging from decorative street lighting, commercial parking lot lighting, car lot lighting, outdoor landscape lighting, architectural lighting, security lighting, and general site lighting. Traditionally, their biggest drawback has been their short lamp life-only 7,500 hours on the average.
Newer designs in Metal Halide commercial lighting fixtures include pulse start technology and ceramic metal halide design. These improvements have increased lumens per watt efficiency, control of the light itself through superior dimmability, better stability of color rendering, longer lamp life, and shorter start time.
Unfortunately, recent legislation has called for the phase out of certain standard forms of MH commercial lighting fixtures due to their use of incendiary elements that fall under the classification of greenhouse gas sources. This in turn paves the way for the most sophisticated lighting ever developed on our world, and quite possibly, the singular source of lighting used both commercially and residentially in the very near future: LED commercial lighting fixtures.
LED Commercial Lighting Fixtures
As technology improves, the ability to create truly “white” led light continues to evolve. LED commercial lighting fixtures are featuring higher lumens per watt efficiencies than their initial prototypes initially offered. This has opened the door for a number of architectural lighting and site lighting applications that were previously the exclusive domain of HID commercial lighting fixtures.
We are also seeing an upsurge in the use of led commercial lighting fixtures in street and roadway lighting, where a number of municipalities in the United States and Europe have reported some very promising findings in regards to both power cost reduction and the overall quality of street lighting itself.
Look for quarterly leaps and bounds in the engineering gains made by LED commercial lighting fixture manufacturers, and be sure to sign up for our RLLD Commercial Lighting Newsletter which will feature news updates and case studies about this exciting and revolutionary technology.

Average rate to paint a 1 story house?
I have an elderly women whom I do side work for. She has roofing contractors doing her roof that her son payed for. She offered to have me paint her house maybe in the springtime when I’m not doing much for work. What should I charge her, she want’s me to give her a price by the job so she knows how much it will cost her total. I don’t really mind, seeing how I don’t work, and do basically nothing at all…what should I charge her to paint her 1 story, 2br. house. I can reach everything with an 8ft. ladder. I figured it would take me maybe 4 day’s it’s a light blue color, and only needs one coat.
$800-$1200.
Electrical Contractors, Electrical Installation Services
In by gone days all a contractor had to do was give the customer good quality and good service and he/she would be set. Then set back and let your customers do your selling for you. They would tell a friend and then that friend would tell a friend. Your phone would be ringing off the hook. I remember as an Architectural designer some days I would have up to four people wanting to schedule appointments for designs. Those days are long gone! But Fear Not! Click Here For Help
