LED lights greatly outlast CFL bulbs, incandescent bulbs, and halogen bulbs. In addition to long life, they produce an equivalent light quality using only a fraction of the energy required by other bulbs.
Found often in schools, hospitals, offices, retail settings, and for grid ceiling applications, LED troffers are rectangular light fixture that fits into a modular dropped ceiling grid, which are usually 2’x2′ or 2’x’4. Troffer fixtures initially used fluorescent bulbs, such as the T5, T8, or T12. There are LED Troffer retrofits available or if you are putting in new fixtures, high-efficiency LED lay-in troffers and LED Flat Panels are available. These fixtures are available in multiple lumen light outputs, and warmer white (35K), cool white (41K), and bright white (50K) colors.
Many LED panels deliver a polished look with their sleek design and advanced light dispersement. This Maxlite 2’x4′ LED Volumetric Troffer model runs on 45 watts and generates 3985 lumens.
One of the best advantages of using LED 2×4 Troffers, is that the bulbs generally last 50,000 hours, versus only 30,000 hours for an average T8 LFL. This means less calls to the maintenance department to change bulbs in the facility.

During an emergency, the power often goes out and standard exit signs do not give off enough light to enable people to see down hallways or stairwells. LED emergency lights and exit sign combinations are a cost effective way to comply with building codes and help people safely exit a building.
Emergency signs are illuminated 24 hours a day. Incandescent emergency lights use about 40 watts of power compared to 5 watts used by LED signs. Multiply this amount by the number of exit signs in your facility, and you can calculate a considerable amount of savings which you will see on your monthly bill.
Another advantage of LED bulbs is that they usually last for at least 10 years. Incandescent and fluorescent lights on the other hand, only last for an average five months or one year respectively. This means that your maintenance costs will also decrease, as you won’t need to replace bulbs very often.
Easy to install, LED emergency exit signs are a fast and inexpensive way to make your building more safe and energy efficient.
If you are looking for a bright, energy-efficient light that can be used in a commercial or residential space, LED T8 U-bend lamps are a great solution.
A U-bend lamp is a linear tube that has been shaped into a U. LED T8 U-bend lamps operate off a fixture’s existing ballast, without any extra labor or rewiring. It is a plug-and-play replacement for fluorescent tubes that works straight out of the box, and is suitable for use in a totally enclosed, bi-pin socketed luminaires.
Designed to deliver over 1800 lumens, these energy-saving LED lamps are quick, easy, and safe to install.
The Department of Energy has compiled a great deal of helpful information about the advantages of LED lights. They have found that decorative LED light strings consume far less electricity than incandescent bulbs and have a number of other advantages. They are:
Safer: LEDs are much cooler than incandescent lights, reducing the risk of combustion or burnt fingers.
Sturdier: LEDs are made with epoxy lenses, not glass, and are much more resistant to breakage.
Longer lasting: The same LED string could still be in use 40 holiday seasons from now.
Easier to install: Up to 25 strings of LEDs can be connected end-to-end without overloading a wall socket.
The estimated cost of electricity to light a six-foot tree for 12 hours a day for 40 days is .27 cents for C-9 LED lights v. $10.00 for incandescent C-9 lights.
Another thing to keep in mind when you are shopping for holiday lights is whether the strands utilize half-wave or full-wave technology. All LED lights cycle on and off many times per second. The cycle speed of full wave lights is 120 times per second, which is undetectable to the human eye. However, the cycle speed of half wave lights is 60 times per second, which is noticeable to many people.
In addition, full wave LED lights:
Produce between 30-40% more light output
Appear to have brighter and truer colors
Have no visible flicker, even in windy conditions
Whether you are looking for lights for your home or business (such as wedding venues, retail window displays, or outside lights for your office) LEDs are a safe, affordable option.
Gone are the days when energy efficient lighting conjured up the image of a greenish buzzing haze. Vast improvements over the years, including the recent accessibility of LED options, have allowed people and companies to affordably transform their space.
New lighting was installed throughout the building, including LED tubes which replaced fluorescent tubes and dimmable LED bulbs were installed in lamps.
While Conservation Mart was not involved in this library renovation, we carry many LED troffers which can transform your living and working environments.
When choosing the right bulbs for your needs, you will want to consider the following five factors: wattage, lumens, base, color temperature, and maximum overall length (MOL). For a more detailed description of these attributes, please visit our informational web page on this topic.
One of the most useful measurements when referring to a lighting source is the Color Rendering Index, also known as the CRI. The CRI measures the ability of a light source to accurately show all frequencies of its color spectrum when compared to a perfect reference light, such as daylight. In other words, it is a measure of a light source’s ability to show object colors “realistically” or “naturally.” CRI is rated on a scale from 1-100. The lower the CRI level, the less accurately colors will be reproduced. The higher the number, the better the color rendering ability.
For a light source to be considered to have a “high CRI,” it must measure to be a 90 or above. For this reason, this CRI level is also the most acceptable for professional projects and imaging. Â This simply means that these bulbs are the closest to showing true object colors, or having a perfect CRI of 100. Light sources that are incandescent radiators have a CRI of 100 since all colors in their spectrum are rendered equally. Often times, LED light bulbs with a high CRI can be worthy replacements for incandescent light bulbs. Although high CRI bulbs can be used for several different projects, depending on the desired illumination, they are usually an excellent choice for retail, art galleries, museums, high end homes or anywhere extreme color accuracy is required.
The old-school Edison style light bulbs of the 20th century were evolutionary yet far from the different variations of light bulbs that have been developed today. The first models of light bulbs developed by Thomas Edison used carbon filaments and wasted a ton of energy and subsequently, a ton of money as well. Although it is rare that any of these initially developed models are used today, the perception of what some of the first light bulbs looked like has not been forgotten and has recently become the perfect way to give any space an antique finish.
Now, with new LED models of these old-school Edison bulbs, anyone can achieve a vintage look in their home or establishment while simultaneously saving energy. For example, an Edison style model from Bulbrite only uses 4 Watts of energy, which compares to a 40 Watt incandescent and has an average long life of 15,000 hours.
Homeowners everywhere are loving this trend and have found a number of different ways to display and use these light bulbs to an extra touch to their interior/exterior design. There are several different models of the Edison style bulbs, such as A19, Globe, Chandelier, and Torpedo, making them suitable for a variety of locations including outdoor lanterns, ceiling fixtures, pendants, and more. Vintage Edison light bulbs offer all-in-one satisfaction by combining style, energy conservation, and convenience.
Dusk-to-dawn LED fixtures are triggered on and off by the amount of light reaching the fixtureâ€™s sensor, making them suitable for outdoor areas such as streets, roadways, parking lots, and pedestrian areas. The dusk-to-dawn feature of a light will cause your motion light to activate only when it is dark.Â This feature uses a small photocell to detect the presence of available and/or existing light.Â If light is detected, the motion light will not trigger.Â If light is not detected, the light will turn on once motion is detected. Therefore, during the day when natural light is present, the light will not activate when motion is detected, which saves energy. Here is a breakdown of the features and advantages that come with the dusk-to-dawn feature:
Automatically triggered on and off by the amount of light reaching the fixtureâ€™s sensor
Great light output and efficiency
Inexpensive and widely available
Significantly longer life
Security: Provides enough light to see an intruder and, therefore, deters an intruder from entering an area
Safety: Mishaps and accidents can be significantly reduced if you illuminate doorways, sidewalks, and driveways
Convenience: You donâ€™t have to remember to switch the light on or off
Conservation: Offers low intensity to conserve electricity and to keep from disturbing neighbors
Dusk-to-dawn lighting can be a useful addition to your home or establishment. Remember, when choosing the type of dusk to dawn lighting source you may need it would be best to check the lumen output of your fixture based on how much light you would like the light to emit, as light intensity is measured in lumens.
The main difference between a LED MR16, GU10, and PAR16 light is that the bases are different. Both MR16 and GU10 use pin bases that look and work differently. This is done so that bulbs do not get confused during installation. Since MR16 bulbs run on only 12 volts, they need external transformers to convert the building’s main 240 voltage supply to the 12 volts needed to run these bulbs. On the other hand, GU10 based bulbs can simply be plugged in and are ready for action. Some MR16 bulbs also come with other pin bases such as GU5.3.
As far as MR16 vs. PAR16, the main difference is the size, variety, and heat. Unlike MR16 type halogen bulbs which have dichroic glass reflectors, the PAR bulbs have aluminized glass reflectors which direct the heat generated by the bulb to the front of the bulb. Because of this, PAR16 bulbs are usually not suitable for ceiling installations of 8 feet or lower. PAR16 bulbs also produce more directional yet duller lighting and have a standard, medium screw-in type of base and work in medium sized E26 sockets. MR16, on the other hand, generates heat to the rear of the bulb and produce a lot more light for the wattage because of the multi-faceted reflector (hence, MR).
Although these three types of bulbs are different and should not be confused for correct installation, they will all save energy and minimize replacement and maintenance costs. Switching to any of these bulbs today can show you savings in as little as one year!
LED T8 tubes, which used to be exclusive to fluorescent technology, are the new standard for commercial and household lighting. These tubes are ideal for replacement, emitting the same amounts of light as fluorescent T8s yet using a fraction of the power and lasting up to three times longer. LED T8 tubes are also mercury-free, dimmable, more efficient, and have high-quality directional light. When replacing your fluorescent tubes with LEDs for your home or workspace, it is important to be aware of these two types of technologies:
T8 lamps with internal drivers are 1 of 2 ideal energy saving choices when upgrading traditional linear T8 or T12 fluorescent lamps in fixtures. With internal drivers, the ballasts are removed from the fixture and the power is wired direct to the sockets. Since no power is wasted on the ballast, these type of tubes tend to be more efficient. Consumers also experience less long term maintenance costs since you have one less part to maintain in the future by eliminating the ballast. These LED T8 tubes are designed to provide appropriate light levels while utilizing a dedicated internal driver. However, some cons associated with internal drivers include: required electrical modifications, limited dimming, dangerous installation and higher installation costs.
T8 lamps that are instant start compatible require no rewiring of the fixture. Since this step is not necessary, instant start tubes offer a simple way to replace the fluorescent lamp with your new LED lamp. Instant start ballasts ignite lamps by applying a significant voltage across the lamp during starting. However, no cathode heating is applied before or after the lamp ignited. The high voltage applied across the lamps typically ignites them within 50 milliseconds. Emissive material is also released during this since the cathodes are not heated with instant start ballasts. It is the most energy efficient type, but yields the fewest lamp-start cycles, as material is blasted from the surface of the cold electrodes each time the lamp is turned on. Instant-start ballasts are best suited to applications with long duty cycles, where the lamps are not frequently turned on and off.
