They have the sparkle and definition of sunlight, and they are best suited for frequent on-off situations. The following are ways to reduce energy costs with incandescent lamps. High Efficiency Incandescent Lamps High efficiency incandescent lamps can yield substantial savings. The lower powered ER lamp is designed to project more light out of the fixture than the floodlamp. A 75 watt ER replacing a 150 watt regular floodlamp often yields more light, and uses half the power.
Energy savings can be substantial.
If you need more light, try a larger ER lamp, or a socket extension that brings the front surface of the lamp closer to the opening of the fixture. In many cases you can use a single, more powerful lamp where you now have two or more. A 20 watt reduction saves 15 kWh of electricity over the life of a new lamp, enough to justify replacing lamps before the old ones burn out. Old lamps can also be used as temporary replacements in areas that are now over-lit. All Rights Reserved.
