Even though our LED's are red, our scoreboards use so little power you should think of them as green.  Most of our scoreboards require a single 110 volt outlet, but internal transformers change that to 12 volts.  In other words, a 6 lane alpha numeric scoreboard with every LED turned on will use about as much energy as a single 500 watt light bulb.  Of course, most of the time the LED's are off.  That translates into substantial energy savings over mechanical scoreboards and full graphic scoreboards.  Upgrade your scoreboard, save on operating costs and go GREEN!
