Life expectancy of a lamp is determined by how long the lamp lasts without any major color rendering degradation or burnout. Many variables can affect lamp life including the manufacturing process: the pressure of gas inside the tube and the quality of components used; along with the characterisitcs of the display case: mainly the type of ballast.

As an example, two lamps with the same color spectrum or temperature but engineered by two completely different manufacturers will have a very different life expectancy. and the integrity of their continued illumination and color rendering properties will also differ over time.

Absolutely! PROMOLUX is only involved in the manufacturing of lamps, not the light fixtures.

Just check your ballast for the appropriate wattage and tell us what type of lamp is currently in the case and we’ll help you find the right light for your business.

A number of years ago, certain types of lamps for meat displays were coined the name “meat lamps” because of the intense red color emitted. Consumer groups were not happy with this and in turn in many states, the use of red lamps were made banned as they obviously misrepresented and distorted the true color of meat products.
