Supermarket Lighting - Converting over to LED

Food Processing Lighting in Supermarkets is a big deal. 100's of shoppers visit the store every day and its the goal of the supermarket to present the food in the best possible manner. It is so important for the packaging on the food items to be vibrant and colorful.

Saving money with LED means nothing unless the quality of the light meets the requirement necessary to produce the necessary high quality of light. This is called Color Rendering Index, or CRI for short, and it is the standard by which the quality of light is measured.

Thankfully, LED Lights by default have high CRI, but what CRI do you really need? Most standard LED products start at CRI 70. For grocery store lighting, we suggest 80+ CRI which proves that LED lights for grocery store environments to be the perfect option due to the flexibility and quality of light they offer.

Supermarket Lighting Fixtures typically consist of rows of fluorescent lighting hung directly over the aisle or Metal Halide High Bays suspended from the ceiling. In either case, our supermarket LED lighting solutions allow you to either replace or retrofit your existing fixtures.

Replacing Fluorescent Lighting in Supermarkets

If your supermarket contains fluorescent lighting, converting your store to LED is relatively simple. LED Tubes can simply replace your existing fluorescent tubes if you choose the tubes that can run off the existing fluorescent ballasts. Some prefer to remove the ballast completely, and there are tubes that work from direct AC input from your existing fixtures. Retrofitting your fluorescent fixtures to accept an LED Tube is simple and straightforward. If you decide to remove or bypass the ballast, then an electrician should do that work. If you decide to use the model that works with the existing ballast, a maintenance person can perform that task. As long as you turn the lights off before you replace and don't try to replace the tubes 'hot' you will be fine. In this way, converting your grocery lighting over to LED is simple and painless. And in terms of cost reduction, expect 50-66% energy savings. And you will notice the store is brighter.

The same goes with the lighting in your freezer section, converting over to LED grocery store lighting is simple and cost effective. In this case, there are special LED Tubes and fixtures already designed to take into account the unique requirement of distributing the light from the front of the cabinet to the back so all the product lights up properly. Like the tubes above, DLC Qualified Products are available that allow you to receive a rebate back from your utility company. This in turn allows your new and upgraded supermarket lighting design to be the best available option you could go with.

Replacing Metal Halide High Bays

Converting over from Metal Halide to LED is also a simple task. Replacing the fixtures are easy, but if you have a lot of money tied up in the fixtures and want to keep the, retrofitting your supermarket lighting fixtures to LED is simple as well. New fixtures now have an up-light option, redirecting some of the light upwards to light up the ceiling. This makes the store more inviting and reduces the cave affect that can occur with directional lighting. The majority of High Bay fixtures are DLC Qualified which makes them eligible for utility rebates - further reducing the cost of conversion and lowering your payback period.

Why we think T5 fluorescent is a bad idea

We do not sell Fluorescent Products, so we know this next conversation may sound like it is a pure marketing pitch. But here us out. A typical T5 fluorescent fixture to replace 400W Metal Halide is a 6 tube T5 54W HO fixture. With ballast, each bulb consumes approximately 60 Watts each. So the entire fixture consumes 360W, down from the 400 (+ 55) watts the Metal Halide High Bay consumes.

With LED, why not consider converting over to the 150W or 200W LED High Bay. This represents a significant savings over the Metal Halide Fixture it replaces, and a significant savings over the T5 fluorescent fixture. And now that LED is mainstream, the cost of a LED fixture with rebates is on par with that of the T5 fluorescent fixture. It makes absolutely no sense to convert to T5 fluorescents only to discover how much more you can save with LED High Bays.

And this discussion isn't even about the extra maintenance you will have to do swapping out T5 bulbs and T5 ballasts. Do that a few times and you will wish you had selected LED.

Outdoor LED Supermarket Lights

We recently completely a retrofit of a parking lot for a supermarket. The issue was the supermarket had a large investment in their fixtures, they matched the poles, so they did not want to replace the fixtures. So we converted them over to LED with our 100W LED Retrofit Kit, and after rebates, they were able to convert 20 lights for about $1000. That's about $50 a light. And the light levels improved as well as the energy consumption dropped from 455 Watts per fixture to 100 Watts per fixture. Because our retrofit kits are DLC Premium Qualified, the rebates were significantly more than a DLC Standard Qualified Product. And to match our lumen output, some competitive retrofit kits would have to consume 30 to 40 more watts per fixture. That is the benefit of having extremely high efficient LED product - better and bigger rebates and less energy consumption.

Along with retrofitting their area lighting, we also replaced all the wall packs on the building, creating a safer brighter space and reducing energy consumption by over 65%. And don't forget; your interior grocery store design is highly important just as your outdoor design is. They are both critical to creating a good image and improving customers visits to your store.

Another option that was not available with Metal Halide lights is to add motion sensors on top of the photo cells. With bi-level dimming, you can actually dim sections of the parking lot down when no one is around and bring it to full brightness when a car or person enters the area. This can dramatically reduce your energy spend even more. Think of the scenario where you convert 400W Metal Halide to 100W LED. And then add a motion sensor that drops energy consumption to 20 Watts when no one is around. You have effectively reduced energy spend from 455 Watts to 20 Watts. And that all affects your bottom line.
