Is LED Lighting Right for Your Building?

Vanguard Building Solutions, a national energy efficiency and specialty mechanical solutions company offers these tips to determine if LED lighting is right for you.

What is available in LED lighting and can it be affordable for building owners and tenants?led-lighting

• 2×2 and 2×4 lay-in LED fixtures are now cost competitive from major manufacturers
• 6” cans have LED retrofit kits that are reasonable and can save up to 80% on your energy consumption
• LED replacements for compact fluorescent plug ins are available and can save almost 60%
• Incandescent screw in lamps to LED have been around and the cost has come down considerably
• LED stairwell fixtures allow for 50-70% savings
• Outdoor/parking lot fixtures – the right LED fixture can save 70% on energy, provide even distribution of light and have a life expectancy of 22-25 years!

Benefits of LED Lighting:

• Indoor fixtures have an expected useful life of 50,000 – 75,000 hours
• Outdoor fixtures have an expected useful life of 100,000 hours
• Even distribution of light
• Will be perceived as brighter based on the quality of light
• Security – facial recognition is much greater with LED light than any other light source
• Many options to match look of existing fixture
• Maintenance free
• At the end of its useful life the fixture still operates but at a lower light level – doesn’t fail and turn off

Drawbacks of LED Lighting

• Still more expensive than fluorescent
• Many 2nd and 3rd tier companies selling low-quality LED products to compete on price
• After 15 or 20 years you will need to replace the driver in the fixture or the fixture itself

Should I consider LED lighting technology for my building?

Only you can answer that question but it makes sense to get educated on the technology, costs and benefits for your situation. LED pricing has come down and many facilities are seeing 2-4 year paybacks from new LED lighting.

What should I know before doing an LED retrofit?

• Who is the manufacturer?
• What is their warranty? (some large manufacturers are offering 10 year warranty’s)
• Find a lighting company that has the capability to do photometrics (layout areas of your building with a software package and be able to show you light levels before and after installation)

The Pros and Cons of LED Lighting

THE PROS & CONS OF LED LIGHTING (PDF)

By Ross Greenberg, IALD, LC LEED-AP O&M, President, ZLED Lighting 
LED Lighting has become highly popular for various reasons. They are useful, versatile and create white light, colored light, and so much more. But before opting to use these for lighting your facility, you must do a complete analysis of them in order to know why they are so different compared to other types of lighting. Once you know the pros and cons of LED lighting, you will be able to make the proper decision regarding the the kind of lighting that will best suit your facility.

Let’s explore the Pros and Cons of LED Lighting

The PROS of LED Lighting

Excellent color rendering-LEDs do not wash out colors like other light sources, such as fluorescents, making them perfect for displays and retail applications.

LEDs have a lot of power, which will provide white light illumination for wide areas.

LED lighting translates to significant savings in terms of lower energy bills. In addition to saving money, this also means you’re doing your part for the environment and contributing towards reducing greenhouse gas emission.

LEDs are more durable than any other kind of lamp. This means they last longer, resulting in less maintenance costs and a decrease in the amount of bulbs what would need replacing.

Making use of LEDs in your light fixtures means creating more direct, efficient illumination. This is due to the specific way in which LEDs produce light. They are able to emit light in specific directions and can easily be used as spot lights for very specific areas.

The diodes in LEDs are able to create efficient light without producing any heat.

LEDs do not contain mercury, unlike compact fluorescent lamps.

LEDs are ideal for use in applications that are subject to frequent on-off cycling, unlike fluorescent lamps that burn out more quickly when cycled frequently, or HID lamps that require a long time before restarting.

When used in applications where dimming is required, LEDs do not change their color tint when the current passing through them is lowered, unlike incandescent lamps, which turn yellow.

LED lights will fit in virtually any kind of light fixture.

The CONS of LED Lighting

Over time, some LEDs that have a poor design can begin to flicker, change color, become dim and might even provide uneven light. In order to avoid all these issues, you must always choose LEDs from a trusted supplier. High quality LED’s will be bright, provide proper light output for a long period of time and good color quality, as well as efficiency. They would provide instantaneous lighting and no flickering.

The biggest drawback of LED lighting is a higher purchase price, but their energy efficiency compensates for this cost is in a short period of time. LEDs must be supplied with the correct voltage and current at a constant flow. This requires some electronics expertise to design the electronic drivers.

LEDs can shift color due to age and temperature. Also, two different white LEDs will have two different color characteristics, which affect how the light is perceived.

LED performance largely depends on correctly engineering the fixture to manage the heat generated by the LED, which causes deterioration of the LED chip itself. Over-driving the LED, or not engineering the product to manage heat in high ambient temperatures, may result in overheating of the LED package eventually leading to device failure.

LED retrofit technology is becoming more and more popular as a relatively straightforward and simple solution for energy savings. LED fixtures cost more to purchase than traditional light sources, but there are many factors that contribute to the effective and economic performance of LEDs, so a range of payback scenarios exits. But a lower wattage luminaire significantly reduces the payback period. Before making any decisions to make the change, make sure you ask all of the pertinent questions that are relative to your facility’s needs. You owe it to yourself and your company to talk with a lighting professional to ensure that you are making all the right decisions.

NOTE:
Most companies look at changing over to LED Lighting and decide not to do it because of the initial cost BUT REMEMBER ONE THING…… You will still be paying the higher energy costs to the Utility company so why not put the energy savings back into your pocket.
