Restaurants use roughly two-and-a-half times more energy per square foot than other commercial businesses. Kitchen appliances are an obvious source of waste. Running industrial refrigerators, ovens and fryers can all add thousands of dollars to an owner’s annual energy costs.

One cost factor restaurateurs may overlook is lighting, which represents up to 13 percent of the average energy consumption in a full-service restaurant, according to Energy Star. On average, most restaurants keep lights on for 16 to 20 hours a day.

All those Edison-style incandescent bulbs you see at the trendy place downtown may look great, but their high upfront cost and short lifespan can make for a poor financial investment. Meanwhile, energy-efficient lighting has made great strides over the past few years, in terms of both cost and quality. High-quality LED lighting can cut energy consumption by up to 85 percent and retail prices are dropping quickly.

With that in mind, we’ve put together seven easy tips for LED lighting that will help your restaurant’s bottom line, while also adding to the ambience:

1. When buying LED bulbs, look for a minimum of 25,000 hours, which is about three years if the bulbs are on 24 hours a day. Is the product Energy Star certified? Is the product UL Listed for use in any orientation, in a fully enclosed fixture like a jelly jar that you often see on a range hood, or for use in damp environments like a restaurant kitchen? If the answer to all those questions is yes, then chances are you’ve found a good product.

2. Start off small. Instead of a full retrofit, switch out LED bulbs in the fixtures that are “on” the most, like exterior lights and the overhead lights in the kitchen. Your ROI is greatest on the lights that burn the longest. Next, focus on hard-to-reach fixtures. Is it difficult—or do you even need extra equipment—to reach bulbs on a high dining room chandelier. Is there an enclosed fixture over a stairwell that seems to burn out bulbs? Install quality LED bulbs in those fixtures now and avoid the headache and maintenance cost of changing them every month.

3. Experiment with different output and color temperatures. You can often use a lower watt-equivalency bulb because the LED bulb appears brighter. For example, a cheaper 40 watt-equivalent LED bulb can sometimes be as bright as the old 60-watt incandescent bulbs you used to buy for your dining room. Unless you’re required to provide a certain foot-candle for a specific workspace, aim for the best lighting levels and save more energy while you’re at it. Or, start with the brighter LED bulb and dim to exactly the right level. You will cut energy costs and can always raise light levels when you want.
