Energy Savings

We have thousands of government buildings, and millions of fluorescent lamps. In my building we have the double bulb lamps. If you loosen one the other will still provide adequate lighting. This provides a ready spare on hand. You do this to all of our buildings and cut your lighting savings by half. Additionally you will have less UV exposure indoors.

Replace all fluorescent tubes with LED-tubes

LED-tubes are direct replacements for fluorescent tubes, but do not need ballasts. Thus, LED-tubes can be used in existing fluorescent fixtures (once ballasts are removed), and save about 75% electricity compared to the fluorescent tubes. There are numerous manufacturers, the LED-tubes have 4-6 times longer lifespan than fluorescent, and contain no mercury. The only downsides are: the upfront cost, which is substantially... more »

Deactivate Half of the Florescent Bulbs in Overhead Lighting

In existing buildings where more than sufficient lighting exists, rotate half of the bulbs in each overhead fixture by 45 degrees to deactivate them. That could save up to 50% of electricity used for overhead lighting with no upfront retrofit investment. Many areas I work in are far too brightly lit. The excess lighting is often visually uncomfortable and a gross waste of energy.
