Saving on Air Conditioning and Refrigeration with Efficient Lighting

LED products are typically advertised based on their direct energy savings, but they also offer significant maintenance savings due to their long service life. Also, in applications where lamps operate inside air-conditioned or refrigerated spaces, there are considerable savings to achieve by reducing the heat emission of the lighting system, and by extension the load […]

A Guide to Financial Analysis for LED Retrofits

A Guide to Financial Analysis for LED Retrofits

Why Retrofit to LED Lighting? When the lighting in a facility is upgraded to LED, the main benefit achieved is a direct reduction of the watts consumed by each lighting fixture, while keeping the same luminous output. These benefits are evident just from looking at luminaire specifications; for example, if you replace a 460-watt metal […]

How Lighting Technologies Compare in Terms of Efficacy

The luminous efficacy of a lamp is the ratio of lighting output to power input, and it is measured in lumens per watt, or LPW. In lighting applications, there is a minimum lumen output to meet in order to provide adequate illumination levels. Higher efficacy technologies can achieve the target output with a lower power […]
