Premier Lighting Case Study: Fluorescent to LED Cooler Lights



Customer Profile: 

County Line Liquor in Forest Lake, MN is a full service liquor store that has been a Premier Lighting customer for several years. In the past, Premier has retrofitted their T12 fluorescent fixtures to T8 lamps, and more recently installed LED BR30 lamps in their wine room. The latest lighting upgrade included replacing their T12 HO refrigerator lamps and fixtures with LED case lighting.

Goal: 

Refrigerator cases often have T12 lamps that are not energy efficient nor do they present the products as well as desired. Manager Michelle Murphy decided now was the time to upgrade the case lighting to LED to solve both issues.

Solution: 

The inefficient T12 lamps were to be taken out of the cooler doors and new LED cooler lights were set to be installed. Similar to how the T12 fluorescent lamps were using ballasts, the LED refrigerator bulbs were powered by an external driver.

Do LED Bulbs Flicker?
 

With fluorescent lighting gradually being displaced in favor of LED, many thought the days of dealing with flickering lights were over. Despite flickering being less present in LED than with fluorescent systems, it is certainly still a factor. What are the causes of this, and are there solutions?

There are two types of flickering with lights - visible flicker and invisible flicker. Obviously visible flicker is the one our eyes can see, which is when the light output from a given source changes rapidly. It is considered that anything below a frequency of 100Hz can be seen.

Ballast Bypass (Type B) LED PLL Lamps 2G11 Base 40W Replacement

Conventional Fluorescent PLL lamps now have an LED equivalent that is able to bypass the ballast and wire direct to line voltage. Keystone Direct Drive LED PLL lamps come equipped with an internal driver, ensuring there is no need for a ballast or LED driver to operate the lamps. 17W LED replaces standard FT40/2G11 PLL lamps. Frosted lens eliminates pixelation. Suitable for use in dry or damp applications.
