What is a Ceiling Occupancy Sensor

Ceiling Occupancy Sensor High Bay SensorOne of the easiest ways to save energy when it comes to lighting is to simply turn the lights off when leaving a room. While this sounds simple enough, it’s also one of the easiest tasks to forget. As time goes on, lighting technology continues to advance. Also advancing is the technology being used with light bulbs and fixtures. Installing a ceiling occupancy sensor or a high bay sensor is a quick way to start cutting energy use and costs in any building, especially in commercial spaces that undoubtedly consume more energy than residential properties.

How do sensors work?

The sensors use what is known as passive infrared technology (PIR) that turn lights on and off based on two factors: ambient light levels and occupancy. As long as the ambient light is at a certain level, the sensor will keep the lights from turning on. They can also be set to turn the lights on and keep them on as long as occupancy, or movement, is detected. After the allotted time has passed, or no movement is picked up by the sensor, the lights will be turned off.

Where should I install it?

Buildings with high energy usage, such as hotel locations, warehouses, and other commercial and industrial buildings are ideal spaces for occupancy sensors. No intense or extremely difficult programming is required. The sensors are designed to be compatible with standard lighting systems. Additionally, they are programmed to work with CFLs, LEDs, and new fixture/retrofit installations.

How much can I save?

In buildings with high energy usage, lighting accounts for up to 25% of all energy that is being used. The sensors have been tested by the manufacturers to ensure they not only perform at the highest quality, but will last for years. Installing the ceiling occupancy sensor and the high bay sensor saves not only energy and money, but also helps add to the overall lifetime of your lights, as they’ll no longer be in use when they don’t need to be. Installing sensors leads to automatically reduced energy consumption, energy costs, and your carbon footprint.

Retrofitting Parking and Canopy HIDs with LED Canopy Light Fixtures

LED Canopy Light Fixtures
LED Canopy Light Fixtures

For many business, indoor lighting is one of the most important decisions to be made. Equally important, however, should be how the outside is illuminated. For potential customers passing the building at night, or walking through the parking garage, the outside will be their first impression of your establishment. While HID lamps have been the standard outdoor lighting option for years, LED canopy light fixtures help provide many options to create a safe and inviting environment while greatly reducing both energy use and lighting costs.

Light Distribution

LED manufacturers made sure to provide many options to address a myriad of commercial lighting needs. The LED fixtures are available in two different types: Parking Garage Distribution and Canopy Distribution. The lamps also come in different shapes (round and square) to make the switch simple. The shapes allow multiple choices for mounting: ceiling, arm, and wall mount to name a few. HID lamps generally emit a somewhat orange light color. Their LED counterparts however, provide a cool white light. This gives them a much brighter appearance, and helps foster feelings of safety and comfort where installed.

Switching and Saving

Regardless of where the new lights are being installed, you’ll want to make sure the old ones are being properly replaced. LED canopy light fixtures are available in 20 to 53 watt options as replacements for the following HID lights:

  • 20W LED – 100W Metal Halide
  • 30W LED – 150W Metal Halide
  • 40W LED – 175W Metal Halide
  • 53W LED – 250W Metal Halide

The LED technology allows these lamps to use such low amounts of energy while still maintaining brightness. This is because the brightness is not dependent on wattage, but lumens. The higher the lumen count on a lamp is, the brighter the light emitted from will be. Further opportunities for savings are realized through dimmable and motion sensing lamps. By installing the LED canopy light fixtures, you’ll be cutting energy usage per fixture by up to 80% and as a result, energy costs.

Does Ballast Compatibility Matter When Choosing LED T8 Lamps?

Plug and Play LED T8Traditionally, fluorescent T8 linear lamps have been used as the main light source in commercial buildings such as hospitals, warehouses, schools, and more. LED T8 lamps are quickly replacing their fluorescent counterparts. The LED technology provides higher efficiency, many color and lumen options, and sizes. Advancements in lighting capabilities have also led to more options for installation. When deciding on which lamps to replace your fluorescent T8s with, one of the main things to consider is the ballast type. Knowing the difference between a Plug and Play LED T8 and a Ballast Bypass T8 will make the process of switching even easier.

Type A

Ballast compatibility absolutely matters when the LED lamp you’ve chosen is of the UL Type A variety. The Plug and Play LED T8, also referred to as direct fit, is the easiest of the two types to install. This lamp works directly with the existing ballast to quickly replace the fluorescent T8. While this is the simplest installation method, the LED lamp must be compatible with the ballast of the fluorescent it is replacing in order for the new lamp to work. The makers of the LED T8 typically provide a list of compatible ballasts. Make sure to check out this list before purchasing your replacement lamps.

Type B

LED lamps classified as ballast bypass, direct wire, or UL Type B do have a more involved installation. As a result, it is best to hire an expert electrician to complete the process. The Ballast Bypass T8 does just that. The technology of these lamps works straight from the line voltage that flows through the sockets.The process of retrofitting fluorescent fixtures for this LED type entails the removal of any electrical ballasts as well as verifying non-shunted sockets are in the fixture. The initial installation costs of the lamp is made up for by getting rid of the maintenance costs the ballast would otherwise need.

Both Plug and Play LED T8 and Ballast Bypass T8 options provide as much as 40% more savings in energy use and costs when compared to fluorescent lamps. Having an understanding of how the ballasts impact your fixture, installation process, and overall maintenance can help you better choose which lighting option will work best for you.

Benefits of the High Bay LED Retrofit

high bay LED retrofitIn commercial and industrial buildings, High Intensity Discharge, or HID, light fixtures are commonly found. These are high voltage fixtures that use a mix of metals and gases to create a bright and powerful white light. With each year, and as technology continues to advance, there are far more options for lighting than ever before. Among the most energy efficient options for illuminating any space are LEDs. Naturally, the larger the space, the greater the opportunity for savings. Making the switch from an HID light fixture to a high bay LED retrofit in your facility provides great savings in energy, energy costs, and much more.

Stacking up Savings
While HID light fixtures are the standard, their high voltage and wattage requirements result in high energy consumption. This leads to the cost of energy going up along with it. In contrast, LEDs are powered when a microchip receives an electrical current to create the light. The difference in technology is how a 90-watt high bay LED can replace a 400-watt HID light fixture.

In addition, LEDs contain technology called a heat sink, which absorbs the heat that is created by the light. Heat sink technology allows for up to 20% in air conditioning savings, furthering savings in energy costs. As if this isn’t enough, many of these energy saving lights are also DLC listed. This rating means that many of these fixtures qualify for energy rebates with local utility companies.

Where do they go?
High bay fixtures are designed for use in buildings with ceilings that are typically 20 to 45 feet in height. This makes them ideal for installation in gymnasiums, manufacturing plants, factories, warehouses, and other structures with high ceilings. Spaces such as these require illumination from all sides, and the LEDs provide it. The high bay LED retrofit is not only energy efficient, but long lasting. On average, they last as long as 50,000 hours. The long lifespan reduces the need for frequent replacement, which is ideal given how high up they’re installed!

The focus of LED lighting technology is on their power. They are designed to provide illumination of the highest quality without sacrifice. These energy efficient fixtures deliver brilliant light without affecting the temperature of the building, while saving energy and reducing energy costs from the moment they’re installed.

Fluorescent T5 vs LED Bulb Replacement

As recently as 2010, the United States Department of Energy found that nearly 80 percent of lamps being used in commercial buildings were fluorescent. These lights are commonly found in large industrial buildings or other commercial edifices, such as hospitals and schools. They provide up to 75 percent more energy savings than their incandescent counterparts. That being said, as LED technology updates and shifts, even more savings can be realized by switching from fluorescent tubes to LED T5 plug and play or LED T5 direct wire lamps.

LED T5 direct wirePower Up
One of the major identifiers of any light is its wattage. This is the main indicator of how much you’re going to save when you switch. For example, a standard 28-watt fluorescent tube can be replaced by a 15-watt LED lamp. Additionally, a 54-watt high output fluorescent tube is easily replaceable by an LED that consumes only 25-watts of energy. With such a difference in the amount of power being used, savings in energy costs quickly follow installation.

Plug and Play
Plug and Play, or direct wire, LED T5 lamps make switching from fluorescent to LED simple. These bulbs are easy and quick to install. Replacing the ballast in your current fixture won’t be necessary, as it plugs directly into the fixture without any rewiring. This also reduces the the cost of labor and reduces maintenance for facility managers.

Bypass the Ballast
Ballast bypass, also known as LED T5 direct wire lights are slightly different from their plug and play counterparts. These lamps cannot be installed without first removing the existing ballast in a fixture. This is because they operate using the line voltage that flows straight to the sockets, essentially doing what its name indicates, bypassing the ballast.

Time is Money
On average, an LED T5 lamp is rated to last as long as 50,000 hours. This is more than double the standard 24,000 hour life of a fluorescent tube. Installing lamps with this long of a lifespan eliminates the need for frequent replacement. Also worth consideration are warranty periods. Standard fluorescent tubes have a warranty period up to 2 years. Conversely, the typical warranty period for LED fluorescent tubes is 5 years.

These lamps are available in cool and daylight white and designed with high lumen outputs. This provides both consistent color and illumination for a seamless switch. With lower power usage, longer lifespan, and a longer warranty, whether you choose an LED T5 plug and play or a ballast bypass lamp, you’re easily looking at saving as much as 45 percent on both energy usage and costs.

Choosing the Right Faucet Aerator

Choosing the right bathroom or kitchen aerator is one of the easiest steps you can take to save water. However, selecting the right aerator can be challenging because there are so many different flow rates and sizes to consider. A bath aerator typically screws into the faucet spout so it needs to be the correct size and threading. We’ve listed four factors to consider to help your narrow down the aerator that will meet your needs.

Threading

This is probably the most important factor to consider since it will determine if the aerator will fit your faucet spout. The threading will depend upon which country you are in. The first thing to determine is if you need female or male threading. A female aerator has the threads on the inside of the aerator, while a male aerator has threads on the outside of the aerator. In the United States, the thread size are 55/64″-27 for standard-sized female and 15/16″-27 for standard-sized male. A dual thread aerator is very flexible in that it allows you to fit into both male and female threaded sprouts since it has threads on both the inside and outside.

femaleandmale

Flow Rate

A low flow aerator helps you realize water savings by restricting the water flow rate. To be classified as a low flow aerator and have industry certifications such as WaterSense labeled or CalGreen compliant, it should have a flow rate of less than 2.0 gallons per minute (gpm). The technology has improved significantly to compensate for fluctuations in pressure, so that a low flow aerator does not feel like it’s not delivering sufficient water. To seriously cut down on water usage, consider a flow rate of between 0.5 gpm to 1.5 gpm.

Stream/Spray Type

A low flow bubble faucet aerator restricts the water flow from the faucet. This type of aerator adds air to the water flow to enhance the water stream to give the sensation of a larger flow even though it’s dispensing less water. It is ideal for use in both bathroom and kitchens. A bubble faucet aerator typically has a cross mesh screen to act as a flow restrictor and aerate the water. A needle spray aerator produces a shower like pattern when dispensing water. Needle spray aerators are the only choice when you are selecting an ultra low flow faucet aerator e.g. 0.5 gallons per minute (gpm) or lower. Needle spray aerators provide a good coverage of water when washing hands and so are often preferred in commercial applications. They have tiny holes around the base of the aerator through which the water is dispensed. A Laminar Stream delivers a non aerator stream. It is typical found is hospitals/health care facilities where a strong non splashing stream is desired.  

Size

Aerators come in 3 different sizes : regular size, junior or small size and tom thumb size. The regular size is the largest and the housing is the size of a quarter, the junior/small size is the size of a nickel, and the tom thumb is equivalent circumference of a penny.

Keep these factors in mind and you’ll spend less time worrying about returning those wrong aerator, and more time enjoying the extra money you’ll be saving on water savings with a low flow aerator.

DLC Standard vs DLC Premium

Last week, the DesignLights Consortium (DLC), delisted products that do not meet the new quality and efficiency standards. There are new dlcpremiumtechnical requirements for indoor and outdoor Luminaries and Retrofit Kits, and there are now two categories of designation, DLC standard and DLC premium.

The measurements include:

Minimum Light Output or Lumen – This is a measure of the total quantity of visible light emitted by a source

Minimum Efficacy – This is the measure of Lumens per Watts. So for example, if the light output is 5,000 lumens and the wattage is 55, the minimum efficiency is 90.

Correlated Color Temperature (CCT)CCT measures the color of a light source by using Kelvin (K) temperature, which indicates the warmth or coolness of a lamp’s color appearance. The lower the Kelvin temperature (2700–3000 K), the warmer the color of the light, while the higher the temperature (3600–5500 K), the cooler.

Color Rendering Index (CRI) –  The CRI measures the light source’s ability to show object colors realistically compared to a familiar reference source, such as incandescent light or daylight. The higher the CRI, the better the light source renders every color in the visible spectrum. Light sources with a CRI of 85 to 90 are considered good at color rendering. Light sources with a CRI of 90 or higher are excellent at color rendering and should be used for tasks requiring the most accurate color discrimination.

Lumen Depreciation – L70 v L90 – Light sources gets dimmer over time. This dimming is called lumen depreciation. If a fixture had a lumen maintenance of 70%, that would mean it lost 30% of its brightness during its rated life. If it had a lumen maintenance of 90%, that would mean it lost just 1/10 of its brightness during its rated lifespan.

The results are then placed into two categories: DLC Standard v DLC Premium.

DLC Standard Designation

In general, for outdoor lighting, the minimum efficacy ranges from 90-100, and 65-105 for indoor lighting and the lumen depreciation L70.

The DLC Premium Designation

The DLC Premium designation is new, and is only available to complete luminaires and retrofit kits. The primary differences for the Premium designation are the significantly increased efficacy requirements, which in general range from 110-120 for outdoor lighting and 90-130 for indoor lighting.  They also and the need to provide an L90 projection.

To find out more specifics about these measurements, please see the DLC’s Technical Requirements Table.

Rebates

Some utility companies offer tiered rebate programs, so it may be more cost effective to install lights that meet the DLC Premium standards. Before you install your lighting, you can check to with your local utility or the Database of State Incentives for Renewables & Efficiency (DSIRE) to find rebates. DSIRE is the most comprehensive source of information on incentives and policies that support renewables and energy efficiency in the United States.
