About Lamps

LoStOnE asked:


This restaurant has no windows and lighting is an issue. We want a comfortable atmosphere with lighting that helps relieve the cave-like feeling the restaurant has with no windows. This is a high quality restaurant, so dim lighting is usually wanted, but we don’t want the lighting to be too dim. any suggestions?

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.

Christmas Light Safety Instructions:

When using Christmas lights, basic precautions should always be observed including the following holiday light safety tips;

Your holiday lights are not toys! To avoid risk of fire, burns, personal injury and electric shock, the holiday lights should not be played with or placed where small children can reach them.

Do not use Christmas lights outdoors unless the lights are marked suitable for outdoor use. When outdoor Christmas lights are used in outdoor applications, connect the outdoor Christmas lights to a ground fault circuit interrupting [GFCI] electrical three pronged outlet.

Seasonal holiday lights are not intended for permanent installation or use. Store all holiday lights in a dry cool storage area.

Do not mount or place Christmas lights near gas or electric heaters, fireplaces, candles or other similar sources of heat.

Do not secure the holiday light sets with staples or nails since they could damage the protective wire coating.

Do not place the wire on sharp objects.

Do not let the holiday light bulbs rest on the lights supply cord or on any other electrical wire.

Unplug the Christmas light bulbs when retiring for the night or if the lights are left unattended. You can use an approved three pronged plug timer to turn your lights On and Off so you do not have to unplug your lights.

To reduce the risk of fire or electrical shock, do not mount or support the Christmas lights in a manner that can cut or damage the light sets.

Do not close your doors or windows on the Christmas lights or extension cords as this may damage the protective wire insulation.

When the lights are in use do not cover the Christmas holiday light bulbs with cloth, paper or any material not part of the light set.

Only use United States UL approved 110 / 120 volt Christmas lights.

If your Christmas lights are equipped with push-in type light bulbs, do not twist the holiday light bulbs. Pull the bulbs straight out of the light bulb socket.

To reduce the risk of overheating, replace any burned out light bulbs promptly. Make sure you use the same volt and wattage replacement light bulbs.

Always unplug your Christmas lights before installing or replacing the light bulbs.

Do not overload the electrical wiring of the holiday lights. Only connect the recommended amount of party light sets [usually three sets if not stated in instructions] on one continuous light string.

To avoid the risk of fire, do not replace the factory light plug. The factory plug contains a safety device (fuse) that should not be removed. Discard the holiday light set if the plug is damaged.

Always read the manufacture’s complete use and care instructions for the holiday light bulbs.

Safety Tips For Lights With Overload Fuses:

A blown fuse indicates an overloaded circuit and you need to reduce the amount of lights connected to the circuit. A blown fuse may also be caused by a short-circuit. The Christmas light set with a short-circuit should be discarded. Always unplug your lights before installing or replacing the light fuses. To avoid the risk of a fire, replace the blown fuses with like amp and volt fuses.

The Amsterdam Red-light District asked:


Probably you have heard about the Amsterdam Red-Light District

as this is a very famous section in the Netherlands. Much to

your surprise, what you may have heard is true! Here are some

facts about the Amsterdam Red-Light District, a place unlike

any place else.

The famous Amsterdam Red-Light District covers a large area

in the oldest part of the city. It has been servicing the personal

needs and desires of locals and visitors for five centuries, and

thanks to the old buildings leaning at odd angles overlooking

the tree-enshrouded canals that a certain charm tempts you

to linger longer in the area. In this district, music of every

genre can be heard along the streets from a dozen or more

places late at night. And, it is the classier restaurants,

redone streets, and revamped facades that transform what

once dark and dingy into one of the most attractive parts of

town - the Amsterdam Red-Light District.

Prostitution in the District

Did you know that prostitution is legal in the Netherlands?

Yes, it is! It is most concentrated in the Amsterdam

Red-Light District where it has enjoyed a long tradition of

tolerance. It has been reported that since October 2000,

window prostitutes have been allowed to legally ply their

trade. Much to your surprise, the prostitutes in the

Netherlands are also taxpayers. However, discrimination is

still very much part and parcel in this kind of trade as a

number of the prostitutes reported that some banks even

refuse to grant mortgages for instance.

Now, as a legal profession, the government ensures that all

prostitutes are able to access medical care and work in

better conditions by way of regulating and monitoring working

practices and standards. Also, it is worth noting that contrary

to the popular belief, the Amsterdam Red-Light District is

actually the safest area in the city as clusters of policemen

and private bodyguards employed by the girls themselves are

always on duty.

The Chinatown

The Amsterdam Red-Light District is one of the few places on

earthy where you can authentic and really tasty Chinese food.

The restaurants in this district are easy to find as cooked

Duck is typically hung in the front window. However, Chinatown

in itself is misleading as there are also dozens of Malaysian,

Indonesian and Thai restaurants and cafés scattered along the

beautiful canals. Besides the restaurants, there are other

Chinese businesses in the Amsterdam Red-Light District,

including a well stocked supermarket across from the Waag,

near the Nieuwemarkt.

The Red-Light District Today

Amsterdam now prides itself on its wholly liberal and tolerant

attitude. The city embraces, with the Amsterdam Red-Light

District, embraces the fact that people may be into

prostitution, pornography and soft drugs. So, instead of

criminalizing everything, Amsterdam wears its heart on its

sleeve. What you see is generally what you get. So, how do

you get to it? The answer basically lies on which Amsterdam

Red-Light District you are looking for. There are actually three

Red-Light Districts in the city: the main area is in the Walletjes

area, the Singel, and de Pijp.
