Commercial lighting fixtures feature the highest commercial grade lighting fixtures in all major light sources used for building exterior lighting, site lighting, security lighting, warehouse interior lighting, roadway lighting, and security lighting systems.

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 1970s 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 watts 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 manufactures.
