LED Retrofit Kits to Replace Metal Halide and HPS in your fixtures

If you’ve been using outdated lighting technologies in your facility and need to switch to energy-efficient, eco-friendly lighting, LED Retrofit Kits are a great option. Although some facility owners may decide to fully replace their fixtures, most prefer a cost-effective and energy-efficient solution – which is LED retrofitting. With retrofitting, the fixtures remain in place but the old lamps and ballasts are replaced with LED heads and drivers.

The 5 Main Types of LED Retrofit kits

1.    LED Retrofit Kits for Parking lots, Streets, and Poles

Security and safety in parking lots and streets is important for pedestrians and drivers. Quality illumination prevents potential incidents like carjacking and robberies. Traditional lamps – like metal halides, high pressure sodium lamps, and low pressure sodium lamps – were popularly used in the past for lighting poles in these areas.

However, they have been replaced by LED shoe-box lights because of a number of issues – including high energy usage, high maintenance costs, quick lumen depreciation, and their long time to warm-up and cool-down times.

LED shoe-box lights are square or rectangular in shape. They easily provide powerful, effective, wide-scope light for streets and parking lots of any size. Other lights that can replace traditional parking lot and street lights are corn lights and cobra-head lights.

2.    LED Retrofits for Gas stations, Canopies, and Garages

Many gas stations mostly use metal halide lamps. LED retrofits are a great replacement as they are cost-effective and considerably reduce your electric bills and light maintenance costs. You can mount them on the wall or ceiling for clean and bright light.

LEDs not only provide high-quality illumination to the pump area of a gas station, drivers feel safe and the area looks pleasing and inviting. The accurate optical control in LED lamps ensures that light is directed wherever it is required.

3.    Retrofits for Traditional Wall Packs

Wall pack lights are commonly used in commercial buildings. They are typically mounted on the exterior walls of the buildings. They provide security to the buildings by lighting up the walls and nearby areas. Old lighting technologies like metal halide, fluorescent, and high pressure sodium were originally used in wall pack fixtures.

And although they may produce adequate light, they fall short when it comes to energy efficiency, maintenance, and years of operation. LEDs produce the same amount of lumens while consuming much less energy. In fact, LEDs that use 20W-100W are the perfect substitutes for high intensity discharge bulbs that consume 100W-400W.

4.    LED Retrofit Kits for High Bays and Low Bays

For spaces that have high ceilings (10ft or higher) like warehouses, gymnasiums, arenas, retail stores, workshops, and factories, bay lights are the lights of choice. The option to use high bay lights or low bay lights depends on the exact height of the ceiling. For instance, high bay lights are typically mounted on ceilings that are 20ft high and above while low bay lights are installed on ceilings that are 12ft to 20ft above the floor.

Most commercial facilities have upgraded their bay fixtures from traditional metal halides and HPS lamps to efficient LED technology. LED bay lighting improves occupant safety and visibility. Compared to fluorescent and HID lights, LEDs cut light replacement and maintenance costs by more than 50% since they don’t need to be replaced or serviced constantly.

5.    LED-Tube Retrofits for Linear T8/T10/T12 Lamps

Due to the increased demand for energy-efficient lighting solutions by facility managers, manufacturers have designed LEDs to replace problematic fluorescent tubes. Also known as Tubular LEDs (TLEDs), these tubes match the form of fluorescent tubes in length, diameter, and base so that they are easily placed in the existing fluorescent fixtures. There are 3 types:

  • Type A: Ballast-Compatible LED-Tube

This type is powered by an internal driver, replaces the fluorescent tube and uses the existing ballast. This may cause a ballast compatibility problem. If the ballasts have worked for over 5 years plus, you may want to consider type A or C retrofit kits. Old fluorescent ballasts may cause flickering in Type A TLEDs.

  • Type B: Ballast-Bypass LED-Tube

This type is powered by an internal driver and operates from voltage directly supplied to the fixture. The existing ballast wiring is terminated and sockets are rewired. This work must be done by a licensed electrician. Compatibility is not a problem since ballasts are bypassed. But if the existing fixtures are loose or cracked, they will require replacement.

  • Type C: External Driver LED-Tube

An external driver connects to the line voltage and powers this LED. Connections to the ballast are cut off. Type C offers more advantages than type A and B such as a longer lifespan due to replaceable drivers, higher efficacy, less weight because of external driver.

Why You Should Retrofit Traditional Light Fixtures

If your facility’s financial statements consistently show astronomical expenditure on electricity, it’s time to consider investing in LED lighting. The cost of maintaining traditional lighting can be a nightmare for any facility owner or manager. Most facilities and businesses already have traditional fixtures installed and users are left confused about how to upgrade to modern LED technology. The answer is LED retrofit kits.

Some facility managers may hesitate to adopt LED lighting because they believe that the initial cost of retrofitting is high. But the truth is that in the long run, it is much cheaper than maintaining old fashioned light fixtures. Any cost incurred in upgrading to LED technology is justified by the savings you’ll get eventually. The sooner you make the decision to retrofit your fixtures, the better.

Installing LED retrofits is a great way to future proof your building. Future proofing a building maximizes its life value when faced with unpredictable change. Traditional technology is neither energy-efficient nor environmentally-friendly and you’ll have to upgrade at some point anyway. Energy depletion and climate change issues have caused governments to pass laws requiring buildings to be energy efficient, thereby making LED lighting mandatory.

6 Amazing Benefits of Retrofitting

1.    Reduced Energy Costs

LEDs are designed in such a way that they deliver the highest amount of lumens from the least amount of power, reducing energy costs by 75%. This saves you a lot of money in electricity bills. In addition, LEDs do not lose their lumens rapidly like conventional light sources.

2.    Reduced Maintenance Costs

Generally, LEDs have a long lifespan of 50,000 to 100,000 hours. Also, they do not burn out like older lighting technologies, single diodes just stop working.

People usually start to notice a decrease in illumination when lumens reduce by 30%. But LEDs never lose more than 30% of their lumens during their lifespan. They don’t have filaments or glass components like traditional lights which are delicate. They are extremely tough and can generate bright light for many years, so they don’t require frequent replacements.

3.    Environmentally-Friendly

Since LEDs do not draw a lot of electricity, they can greatly reduce carbon dioxide emissions each year, because a lot of the excess carbon dioxide is brought about by electricity consumption. LEDs are made of recyclable materials and most of them end up in recycling plants at the end of their lives. Traditional bulbs use a lot of electricity and are not recyclable. Disposing them means that mercury ends up in landfills and flows in lakes and rivers. LEDs do not contain these harmful chemicals.

4.    Worker-Safety

With poor lighting, workers aren’t able to see hazards or potential danger. Upgrading to high-quality LED lighting enhances safety by improving visibility, reducing accidents and collisions at work. Also, sufficient lighting makes occupants feel safer entering, exiting, and working in a building.

5.    Worker Productivity

Poor lighting causes eye strain, headaches, and lowers workers’ morale. Their attendance may also drop and production errors might increase. With LED retrofit kits, worker productivity improves because the good lighting makes them more alert and they do their work quicker and more accurately.

6.    Rebates and Incentives

Utility companies, local municipalities, and the federal government provide rebates and incentives for businesses and facilities upgrading to energy-efficient LED technology. This greatly helps facility owners and businesses to offset the initial costs. You can search for rebates and incentives for the state you’re living in online.

Does Your Commercial Property Need LED Retrofit Kits?

The common goal of many commercial property owners (and property managers) is to increase the value of their property by reducing maintenance and energy costs. These can all be achieved by installing LED retrofit kits.

You may be wondering if it’s a wise move to upgrade your facility’s lighting with LED retrofits. And while a photometric test is a must, a few things will help you to know if a lighting upgrade is long overdue:

  • The building’s occupants constantly complain about the harsh or poor lighting
  • The light doesn’t reach all important areas and workstations
  • The place looks dull and you want a fresh look
  • The lighting is more than 10 years old

You may also want to ponder on a few questions to determine whether this is the best decision for your property:

  • How old is the lighting in my building?
  • Is the lighting used for 12 hours or more per day?
  • Am I spending too much on lighting maintenance and replacement bulbs?
  • Do I want to reduce my energy costs?
  • Does our lighting technology support our company’s sustainability goals?

Other Factors to Consider Before Retrofitting Your Industrial or Commercial Property

Existing Fixture Condition

The condition of the luminaires in your building will determine whether you will need retrofits or new fixtures. If they are cracked, rusted, scratched, or have broken parts – or if the ballasts are over 5 years old – a full redesign may be necessary.

Access to the Ceiling or Fixture

You will need to assess whether there is need to access the ceiling to replace the existing lamps. If the ceiling must be accessed, contaminants like dust may be released into the space. If it is an old building with an asbestos roof, it may pose a danger. The light fixtures must be handled with utmost care and health protocols must be followed, which increases the costs of the project.

Lighting Controls

Another factor to help you determine if your commercial property needs LED retrofit kits is the need for lighting controls like motion sensors and occupancy sensors. Almost all LED retrofit kits can work with one or more of these sensors.

Occupancy sensors are best used in spaces that are occupied all day while motion sensors are perfect for spaces that are not used regularly. The lights go off when the space is vacant. When natural daylight is sufficient, daylight sensors (photocells) turn off the lights. When these controls are incorporated in a LED retrofit project, savings increase by 32%.

What Is Most Important To Your Business?

Electricity distribution companies are not about to reduce the cost of energy. If lighting takes up a large chunk of your business expenditures, it’s obvious that you need LED retrofits to cut the cost of energy. Upgrading from fluorescent to LED will reduce your energy expenses by 60-90%.

A lot of time and money is wasted in maintaining and replacing older lights in your property. This time and money are better spent on more important business activities. By converting to LED technology, you will greatly reduce your lighting maintenance costs.

Although saving money is important to any business, we shouldn’t forget that the quality of lighting is just as important. LED technology offers advanced light quality, a higher correlated color temperature, and features like progressive dimming.

A successful LED retrofitting project will depend on the goals of your business and how best to achieve them – whether you’re installing the lights outdoors, indoors, in a newly constructed building, or in a remodeled property.

Find out what incentives and rebates are available from your government or utility company. Although lighting rebate programs are sometimes hard to understand, they are very helpful in saving you money. They lower the initial installation costs, thereby reducing your pay-back period. Who wouldn’t want to be ‘rewarded’ to upgrade?

Contracting the right LED supplier and installer for your lighting upgrade is imperative to ensuring that your retrofitting project is successful. They must understand the ins and outs of LED lighting and provide high-quality LED lights. For maximum savings, find a company that will work with you to design a plan tailored to your goals and budget.

Calculating the ROI

As a business owner or facility manager, it’s important to know if upgrading your building with LED retrofit kits will be profitable. It’s not enough to be told that you will save money; you need to know exactly how much money you will actually save and when the investment will start paying for itself.

Calculating the return on investment (ROI) for a LED retrofit project is not a straightforward process. Determining the savings will take more than just comparing your business’ before and after electric bills.

Some important questions to ask yourself include: how much will it cost to retrofit old lighting systems compared to installing new fixtures? How long will it take for the business to get back the initial investment?

The Marriott headquarters in Maryland installed LED retrofits in 2013. The project involved replacing 400W-1000W HID lamps with high-quality LED lamps and installing motion sensors and a few other lighting controls. As a result, the energy consumption went down by 66% and the company now enjoys savings amounting to $120,000 every year.


The Information Required to Calculate a Retrofitting Project ROI

Gathering key information is paramount to accurately estimating the ROI for LED retrofitting. First and foremost, you need information regarding your current lighting system such as;

  • Types of lamps currently installed
  • The current lamp quantity
  • Wattage of current lamps
  • Ballast efficacy of the lamps
  • Number of hours the lamps are on in a day
  • Number of days a week the lamps are on
  • The electricity cost in your area
  • Annual maintenance costs of current system

The next step is to acquire new information on the proposed LED lighting retrofit kits and an estimation of the installation costs.


  1. Calculate the current costs
  • Calculate your current energy consumption in kWh

Current number of fixtures X wattage of fixtures X number of hours each year


  • Calculate the total annual cost of energy

Energy consumption kWh X Rate of Utility (check your electric bill)

  • Calculate your annual maintenance

Total quantity of current lamps X (industry average cost)


  1. Calculate the new LED proposed costs
  • Calculate the new LED energy usage in kWh

Number of LED fixtures X wattage of new fixtures X number of hours used each year


  • Calculate the annual cost of energy for new LED fixtures

New LED energy usage X Rate

  • Calculate the new LED costs of installation

Proposed LED quantity of fixtures X Cost of Installation per LED fixture

  • Calculate the LED cost in total

Proposed LED quantity X New LED fixture cost

  • Calculate the overall LED system cost

Total cost of installation + Total cost of fixtures


  1. Calculate the payback for retrofitting (in years)
  • Calculate yearly energy savings

(Current kWh-New kWh) X Rate of Utility

  • Calculate your business’ yearly savings in total

(New energy cost in total + New total cost of maintenance) – (Current total cost of energy + Current total cost of maintenance)

  • Payback (in years)

Cost of New System in Total

         Yearly savings



A more detailed financial analysis for a retrofitting project should also consider these points

Direct savings made due to the long lifespan of LED technology

Savings are achieved with a LED upgrade which reduces maintenance and labor costs that come with constant lamp replacements. For an accurate reflection of the financial benefits, the projected savings must include the would-be maintenance costs.

Indirect savings in cold storage rooms and on air conditioning

LED lighting releases less heat which reduces the cooling load on the refrigeration and air conditioning equipment. The energy savings are much more in this case than just from lighting.

Many tools are available to easily calculate the ROI. As long as you have the required information, you only have to enter it into an ROI calculator.

In order to easily demonstrate how the ROI is calculated, let’s say you have a warehouse that uses 50 metal halide high bay lights of 400 watts. High electric bills make you consider LED retrofits. You buy 160-watt LED retrofit kits at $480 each.

We will put a metal halide lamp lifespan at 10,000 and wattage at 458w (which is the actual consumption of a 400w MH bulb).

Your payback period will be

⇒ less than 3 years, and
⇒  you’ll have an extra $9000 per year.

It’s never a bad idea to save even more money, so contact your local utility company for rebates and financial incentives. This is an amazing opportunity to offset the cost of your upgrade and increase your total ROI.

  • ⇒ The new LED system will offer electric bill savings of $8,484 each year over the existing metal halides, based on energy savings only
⇒ The new LED system will pay for itself in less than 3 years with an ROI of 35%, based on energy savings only


⇒ The LED retrofits will save you $69,500 within 10 years, when you factor in re-lamping and labor costs


⇒ The LED retrofits will pay for themselves in less than 2.7 years with a 37% ROI, when you factor in re-lamping and labor costs

The Takeaway

All factors considered, installing LED retrofits is a better option than maintaining inefficient HID and fluorescent lamps. In some special cases where the fixtures are cracked or broken, they will need to be replaced completely.

Some facility managers and business owners think that 2 or more years is too long a payback period, but there are not many places where you can make a 50% return (or higher) annually.

LED retrofit kits are the most cost-effective way to upgrade to energy-efficient LED technology – hands down.


At the end of the day, let your business and sustainability goals guide you in making this very important decision.
