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. And, with smart bulb technology, control your lights from smart devices and even change it’s colors. LED technology and pricing have improved greatly in recent years. And, since they last longer (25x longer than incandescent), you’ll save on replacement cost too.

CFLs (Compact Fluorescent Lamp) use a gas mixture “warmed up” by electrical currents to produce light. Although CFLs are not the most efficient option on the market, they produce far less heat and last 10x longer than incandescent bulbs.

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. Halogen bulbs, which work similarly, are also very inefficient and run extremely hot. Eventually, the filament will break and the bulb will “burn out”.
