Light the Way to Energy SavingsMaking the switch to energy-efficient lighting is the quickest and easiest way to start saving money. And with Hawaii Energy’s instant rebates, replacing old inefficient bulbs is easier on your pocketbook.
LEDs: Today’s Best Choice
Know the difference between your lighting options and see how LEDs stack up against the rest.
- Incandescent bulbs use a filament to produce heat, which then produces light. That’s why these lamps are usually hot – roughly 90% of the energy used to make light escapes every time. Eventually the filament will break and the bulb will “burn out”. Halogen bulbs, which work similarly, are also very inefficient.
- CFLs (Compact Fluorescent Lamp) use a gas mixture “warmed up” by electrical currents to produce light. Although not the most efficient option on the market, CFLs produce far less heat and last 10x longer than incandescent bulbs.
- LED (Light-Emitting Diode) bulbs produce light by moving electrons around (through semiconductor material), rather than using a filament or gas. This requires very small amounts of energy and makes them more durable, safer and cooler to the touch. LED technology and price points have improved greatly in recent years, and one LED bulb can save you up to $135 per year and last up to 20 years!
