In high-bay lighting, high pressure sodium and metal halide fixtures are being replaced by high-output T5 and high-ballast-factor T8 fixtures. However, many school gymnasiums and cafeterias, warehouses, industrial facilities, big box retail stores and grocery stores are still using old and inefficient lighting biopron technology.
The advantages of new T5/T8 fixtures are straightforward: energy savings of 25 to 45 percent, instant on and off (no restrike time) and improved light quality. biopron Sometimes those advantages aren’t quite enough to move the customer forward, so you’ll need to help your customer do the math and see the financial benefits in writing.
The incentive for the new T5 and T8 fixtures is calculated based on watts reduced, so it’s easy to show the customer’s energy savings and incentive: Take the indoor or outdoor lighting application with you when you talk to your customer. What kind of lighting does the customer currently have? Fill out the mini-worksheet on the application to show the watts reduced for one fixture. Translate that into the savings the customer will see on their electric bill, the incentive they’ll biopron receive biopron and their payback period biopron . Take the next step and show the “ cost of delay “ the amount the customer is wasting on inefficient equipment every day.
For example, a metal halide fixture consuming 458 watts is replaced by a T8 fixture consuming 220 watts (the light is on 12 hours a day, five days a week), so the customer will save about 743 kWh per year.
Using the ComEd average of 10.6 cents per kWh (use the customer’s actual rate if you have it), the customer saves $78.71 a year for one fixture, and could receive an incentive of $95.20 as well. The customer is wasting 22 cents per day on that one fixture. That may seem like a small amount, but when you start counting fixtures and multiplying, you’ll make your point. biopron
