• Who says copying isn’t a form of flattery?...
Once an innovative new product hits the shelves, it reportedly will be copied from 150 to 300 times with similar products.
• The electric light bulb got its present shape because Thomas Edison accidently dropped a screwdriver on an early light, knocking it out of its original shape and causing it to burn more brightly with increased power.
• The Venetians began selling books by catalog in the 1500’s.
• The final Seinfeld show was projected on the side of a seven-story building in St. Louis.
• Herbert Hoover was the first U.S. President to have a telephone on his desk. Prior to 1929, the President used a telephone booth outside his office.

Below are a few examples of energy-saving opportunities with efficient lighting:
• Installation of energy-efficient fluorescent lamps in place of conventional fluorescent lamps for example: replacing T12 lamps with T8 or T5 lamps.
• Installation of compact fluorescent lamps (CFLs) in place of incandescent lamps.
• Installation of high pressure sodium (HPS) lamps for applications where color rendering is not critical. Metal halide lamps should also be considered when correct color is important.
• Installation of LED exit signs to replace incandescents.
• Installation of high frequency (HF) electronic ballasts in place of conventional ballasts.
• Installation of occupancy sensors, an inexpensive way to ensure that unused lights do not remain on.
• Installation of microprocessor-based controllers.
• Installation of photocells, devices that automatically detect the natural light level in a room and adjust the intensity of the artificial light accordingly.
• Replacing incandescent wall lights and exit sign lighting with CFL or LED-lit units will not only save a considerable amount of energy, it also will significantly reduce labor costs associated with changing light bulbs, since CFLs and LEDs last much longer than incandescent bulbs.
• If the HVAC system is being upgraded or replaced, the lighting system, too, should be reviewed and the loads attributed to lighting recalculated. When the air conditioning system is optimized, the air conditioning loads will be calculated based on existing lighting systems. If a condo plans to upgrade the lighting, it is best to do so at the time of the HVAC retrofit since the lighting and HVAC systems have a large effect on each other
