FAQ

Below are some questions we are often asked.

Lamp Disposal

 

Are LED light bulbs really worth the money?

Yes! LED screw-base bulbs use 75 percent less energy than standard incandescent light bulbs, and they last ten times longer.
If you replace a standard incandescent bulb or compact fluorescent lamp, you can save about $40 in energy costs over the four-year life of the bulb.
Plus, you’ll save on the cost of at least eight incandescent bulbs during that time, as well as numerous trips to the store – and that’s just one fixture. LED bulbs help to save the environment and they are especially good for hard-to-reach/inconvenient places where the lights are on for long periods of time. LED lamps can also be used in standard dimmers, where in most cases compact fluorescent lamps cannot.

Is it cheaper to leave lights on than to turn them on and off several times during the day?

There is not a higher energy requirement for starting lamps that outweighs running them for any period of time.  Although shorter burning cycles (more “on and offs”) can reduce lamp life, it is always better to turn lights off when they are not in use.  Since the cost of the electricity (even in the cheapest markets) is so much more that the cost of replacing lamps a little sooner, you would maximize your savings by turning off the lamps when you don’t need the light.

What is high-bay lighting?

High-bay lighting is used in high-ceiling areas to light surfaces more than 15 feet away. Common high-bay applications include industrial manufacturing, gymnasiums, warehouses, and warehouse-type retailers. The most energy efficient high bay lighting today utilizes LED technology high output T-8 & T-5 fluorescent lamps.

What are the benefits of high-output LED, T-8 and T-5 high bay fixtures?

Switching from HID lighting to LED or high output T-8 and T-5 fluorescent fixtures is now a common strategy for increasing energy efficiency in warehouses and other high-bay lighting situations. LED & T8/T5 fluorescent:

  • Are capable of instant-on and instant re-strike.
  • Can be used with energy-saving occupancy sensors.
  • Can be adjusted through dimming and advanced dimming control systems.
  • Have lower average mercury content than metal halide HID lamps.
  • LED contains no mercury.

What is CRI?

The Color Rendering Index (CRI) measures color rendering from light sources with respect to natural sunlight.  Natural sunlight equals 100 CRI, the best light available.  So the closer the CRI number is to 100, the more closely colors will appear as they do in sunlight.  And lights with the highest CRI numbers product the clearest, most vibrant and natural-looking colors.

What is the Kelvin Temperature Scale?

Color temperature can be quantified using a scale marked in degrees Kelvin. Lighting can vary in color temperature between 2,000 degrees Kelvin (warm) and 9,500 degrees Kelvin (cold); the scale is derived from the fact that the light emitted by heated objects produces a spectrum, which changes as the temperature increases. Low-temperature lighting is progressively warmer (more red/yellow), while high-temperature lighting grows progressively colder (more blue).

What are the major colors which are available in LED light bulbs?

  • Warm White – Use where skin tones and wood tones are important, such as kitchens, bathrooms and recreation rooms.  Usually around 3000-3500K.
  • Cool White – Use where color is not as critical, such as offices, work areas, utility rooms, storage areas and garages.  Usually around 4100K.
  • Day Light (5000K) – The 5000K lamp produces a much whiter light more closely associated with sun light.  The advantage of this light color is that it increases contrast.  Black becomes blacker and white becomes whiter.  This lamp makes an excellent reading light, can be used in areas where precise tasks are being done, and is great in high bay lighting situations.

What is a Candela?

The international basic physical quantity of all measurements of light.  All other units are derived from it.  Its value is determined by the light emitted by a laboratory device operating at a specific temperature.

What is light Efficacy?

A measure used to compare light output to energy consumption.  Efficacy is measured in lumens per watt.  For example, if a 100-watt light source produces 1750 lumens, then the efficacy of the light source is 17.5 lumens per watt.

What is a Foot Candle?

One lumen uniformly distributed over one square foot of surface.  One lumen falling on one square foot of surface produces illumination of one- foot candle.

What is a Kilowatt Hour?

One thousand watts of electric energy consumed in one hour.  Example: One 1,000-watt lamp or ten 100-watt lamps burning for one hour.

What is Total Harmonic Distortion (THD)?

A measure of the degree to which the input current is distorted from a sine wave, measured as a percentage.  THD is usually expressed as a percentage of the fundamental frequency line current.  THD for 4-foot electromagnetic fluorescent ballasts range from 20% to 40%.  For compact fluorescent ballasts, THD levels greater than 50% are common.  Good electronic ballast have less than 10% THD.

What is the difference between an electronic and a magnetic ballast?

A magnetic ballast uses coiled wire and creates magnetic fields to transform voltage. A magnetic ballast does not change the frequency of the power to the lamp—it remains the same as the input power, in the United States 60 Hz.  These types of ballasts for fluorescent lighting are being phased out in the industry. An electronic ballast uses solid state components to transform voltage. It also changes the frequency of the power from 60 Hz to 20,000 Hz, or higher, depending on the ballast. Because the electronic ballast doesn’t use coils and electromagnetic fields, it can function more efficiently and cooler than magnetic. The frequency change also greatly reduces any flicker in the lamp due to burn in or improper power.

What type of commercial fluorescent fixture would be used in an office?

Fixtures used in offices range from types such as the Troffer, Parabolic, Down Lights, Strips, Undercabinet and Indirect/Direct style fixtures.

Do I have to ground all fixtures?

Yes.  You must ground all fixtures for effective use and safety.

Can I use a dimming switch on with LED bulbs?

Yes. BUT, certain LED bulbs dim more smoothly with dimmer switches designed for LED lamps. Ordinary dimming switches work fine with dimmable LED lamps, but sometimes older dimmer switches can make the bulbs flicker.

What does lighting upgrade or retrofit mean?

Retrofitting or upgrading a fixture means converting it from one type of light source to another. This term is used when converting an incandescent fixture to an LED fixture, T-12 fluorescent fixture to an LED, T-8 or T-5 fluorescent fixture, a metal halide/high pressure sodium fixture to an LED, T-8 or T-5 fluorescent fixture, etc.

What is Energy Star?

Energy Star is a voluntary partnership among the U.S. Department of Energy, the U.S. Environmental Protection Agency, service providers, product manufacturers, local utilities and retailers, designed to identify and promote energy-efficient products that reduce carbon dioxide emissions.  Eastern Energy Solutions is an Energy Star Partner.

What is High Power Factor?

A ballast (or fixture) is considered High Power Factor if it is rated at greater than 90%.

Can I put LEDs on a motion sensor?

Yes.  Motion sensors are an excellent way to save more electricity, especially in a low traffic area.  They can be used in many configurations to greatly increase the return on investment and lamp/ballast life in a lighting project.

What is the difference between Acrylic and Polycarbonate?

Acrylic is breakable, but will not yellow.  It is less expensive & can look like glass.  Polycarbonate is virtually unbreakable, but will turn yellow under UV radiation (sunlight & fluorescent lamps).  Both are available in various colors including clear.

What is so special about Powder Coating?

Powder coating is a paint process that uses a dry powder that is either applied electrostatically & then heated, or is applied to a preheated metal surface.  It is safer for the environment than wet paints, creates a harder and stronger coating, & lasts longer than wet paints.  Most quality fixture companies utilize Powder Coating.  Lighting manufacturers also uses galvanized steel and marine grade aluminum in their fixtures to increase durability of the products.

Is it OK to throw fluorescent tubes in the trash when upgrading to LED?

Fluorescent tubes contain mercury, which is a hazardous waste, but the amount in a single lamp is small.  Please check with your local authorities if you are disposing of a large quantity of fluorescent tubes.

Can I use my LED outdoors?

Sure, as long as it is in an enclosed fixture. LED’s also work very well in colder temperatures, so you will have no issues with dim lighting or slow start ups in the winter months. Compact fluorescent lamps do not work as well in cold weather.

What is task lighting and why should we use it?

Task lighting is the concept of providing the correct amount of light for the task being performed.  It does not require the same amount of light to walk down an isle or run a copy machine as it does to read a type written page, so why light the entire environment? When utilizing task lighting, the general light level in the facility is lowered thus creating a softer, more pleasant atmosphere and saving energy.  The work surfaces are then supplemented with task lighting, either under shelf or freestanding to provide the correct amount and quality of light for the task being performed.

What is Seasonal Affective Disorder (SAD), and how can lighting improve this condition?

Seasonal Affective Disorder (SAD) is a serious depression that recurs each year around the same time, starting in the fall or winter, and ending in the spring.  Some of the symptoms typical of depression are sadness, anxiety, irritability, inability to concentrate, withdrawal into solitude and loss of interest in life.  This condition can also cause changes in sleep paterns and changing in eating habits. Treatment: Light therapy, also called phototherapy, is considered the standard treatment of SAD… The device most ofton used is a bank of white fluorescent lights… Controlled studies have shown that using some form of natural lighting such as light boxes or fluorescent lighting greatly improves the mood of people suffering from this condition… For more information, please visit other links related to light therapy on the internet….

Why use LED lamps?

LED lamps are approximately 75% more efficient than incandescent bulbs and last 5-10 times longer. Using them will help lower your electric bill and is better for the environment.

What are LEDs?

LEDs are light emitting diodes. These are electronic components that convert electrical energy directly to light through the movement of electrons within the material of the diode. LEDs are important because due to their efficiency and low energy, they are beginning to replace most conventional light sources.

Why is LED technology classified as solid state lighting?

The term solid state lighting is used because the electronics produce light directly from solid materials in which the electrons are embedded. This is unlike other technologies, for example fluorescent technology, which requires a gaseous discharge medium to initiate production of light.

What makes LEDs more robust than other light sources?

LEDs have no gases, filaments and no moving parts to fatigue. They provide light through a one-step process that takes place within the diode. There is no glass to break or screwed contacts to loosen.

Why do LEDs have a higher initial cost than conventional light sources?

LEDs are made of electronic components that need to be packaged together to offer long lasting efficient light sources to the end user. Apart from the LED chip itself which has sapphire and gallium in the semiconductor, the process of packaging with materials like ceramic, rare earth phosphors, silicone, solder and gold wire add to the overall cost. White LEDs require further tests for calibration and standardization.

What are the economic advantages of using LEDs over conventional light sources?

Although the initial cost of conventional light sources is less than LEDs, the operational and maintenance costs of LED are significantly lower. LEDs, having a longer life, reduce maintenance and lamp replacement cost. . Because LEDs need to be replaced less frequently, the owner spends less on new lamps and the labor needed to change them. LEDs also consume less energy; thus the overall cost of a LED system can be significantly lower than that of conventional lighting systems. Most applications with LEDs offer a payback period as low as three to four years.

How can flexibility in changing color temperature offer more comfortable environments?

LEDs offer the capability of changing from warm white to cool white through digital control of the LEDs. This can be used in indoor or partly outdoor environments where the illumination level and color temperature can be adjusted to match the outdoor conditions (e.g. sunny, clear sky or overcast) depending on the feel required in the space.

Is lifespan reduced if the LEDs are frequently turned on and off?

Unlike discharge lamps, LEDs are semiconductors and their life span is not affected by the number of times they are turned on and off.

How is white light produced by LEDs?

LEDs do not directly produce white light. There are two ways in which white light is produced from LEDs as below:
Using a blue LED with a phosphor coating to convert blue light to white light by a process called fluorescence.
Combining red, blue and green LEDs to produce white light. White light is produced by varying the intensities of the individual red, blue and green chips.

What defines the color temperature of a white LED?

The thickness of the phosphor layer and the wavelength of the blue chip influence the color temperature of the LED.

Why do LEDs produce more vibrant and saturated colors than conventional lamps?

LEDs emit a very narrow spectrum of light. The type of material used in the semiconductor permits only a specific wavelength of light (one color) to be emitted when electrons cross the junction.

What does a life of 50,000 hours mean in the case of – LEDs?

50,000 hours would imply 5.7 years if the light is operated for 24 hours in a day, 7.6 years if the lights are on 18 hours per day and 11.4 years for 12 hours a day.

How much longer does an LED last than a conventional light source?

Typically, an LED will last four times longer than a CFL and 25 times longer than an incandescent source that puts out the same amount of light.
