GOOD POST, mimeatguy, I had a post on the old site about this and one I didn't get to bring over to this site. glad you posted this, I had forgot about this problem in meat case. 

THIS IS FROM A SITE CALLED,

 PROMOLUX LIGHTING INTERNATIONAL                              

Supermarket Fresh Meat Display Case Lighting

Radiation from supermarket fluorescent lighting impacts meat in several ways, changing its color, smell, flavor, rate of decomposition, and marketability. The popularity of organic food means that meats are now on display with fewer preservatives, making them even more sensitive to the effects of light than in recent years and leading to shorter shelf life and faster decomposition, yet customers are more likely than ever to select meat based on its color and freshness. In fact, many studies have shown that color is the primary means by which consumers judge meat juiciness, tenderness, and flavor.

Fresh Meat Displays

Regular supermarket meat display case lighting shortens the brief period when meat is blooming, turning it brown prematurely; increases the rate of bacterial growth; and distorts the meat’s natural color.

Promolux Safe Spectrum balanced full spectrum lamps emit lower levels of heat and ultraviolet radiation than regular supermarket fluorescent lamps, thus reducing the rate of meat decomposition.
