| APPLIANCE | WATTAGE | COMMENTS |
|---|---|---|
| Compact Fluorescent Bulbs | OP 8-20W | Compact fluorescents are definitely the best choice in lighting at this point in time. |
| Fluorescent Tubes | OP 40W SR 400W | Like compact fluorescents, regular fluorescent tubes are among the most efficient forms of lighting available today. |
| Halogen Bulbs | OP 20-50W | Halogen lighting is not energy efficient, despite claims that it is "low voltage": low voltage does not mean low energy use! While better than traditional incandescent bulbs, halogen bulbs are much more inefficient than fluorescents and LEDs. In fact, the excessive and sometimes absurd numbers of halogen downlights installed in many contemporary buildings is responsible for an enormous amount of wasted energy. |
| Incandescent Light Bulb | OP 40-100W | Incandescent light bulbs are highly inefficient and should be replaced by fluorescent alternatives which consume approximately 20% of the power of incandescents for a similar light output. |
| LED Bulbs | OP From 1W | LEDs have exceptionally low power consumption and hold great promise for the future. While they will almost certainly come down in price and improve in performance over coming years, they're not quite ready for the mass market just yet. |
