LEDs and the Cold

All of the different lighting systems respond in various ways to temperature.  LEDs are no exception.  LEDs like the cold, in fact the colder the better for their light output and length of life.  LED's in meat freezers, deli cases and beverage coolers do very well.  On the other hand LEDs do not light the heat.  One of the main reasons for the premature failure of LED's is excessive heat damaging the driver.  With this in mind manufacturing facilities where there can be high temperatures because of equipment or, commercial kitchens with heat from ovens, exterior lighting on a hot roof are all examples of where the LED will not experience its full light output or life.  As with all lighting systems the environment it will be functioning in needs to be a major consideration to be sure that you choose the appropriate one and are able to maximize the life and quality of light output.

Exterior Lighting on during the day?

Drive around any city during daylight hours and you will see poles and building exteriors with their lights on.  This is costing the businesses in a couple of ways.  It will wear out the bulb and internal components twice as fast so they will be paying double for repairs and new parts.  They are also paying twice as much for their electricity bill on wasted light.

Most common causes of lights being on during the day is a problem with the photo cell or if it is on a timer it could be as simple as resetting or adjusting it.  Lighting does have an impact on a businesses bottom line, make sure that you are not spending money on exterior lighting that is not needed in the daylight!
