Types of Bulbs for Bathroom Fan Light Combo
Before you head to the store, it's important to know the different types of bulbs available for bathroom fan light combo fixtures.

Incandescent Bulbs
Incandescent bulbs are the traditional type of light bulb. They are inexpensive but have a short lifespan and consume a lot of energy.
Compact Fluorescent Lamps (CFLs)
CFLs are more energy-efficient than incandescent bulbs and last longer. However, they contain mercury and require careful disposal.
Light Emitting Diodes (LEDs)
LEDs are the most energy-efficient option, with a lifespan of up to 25,000 hours. They are also eco-friendly and contain no hazardous materials.

How to Choose the Right Bulb
When choosing a bulb for your bathroom fan light combo, consider the following factors:
- Base Type: Ensure the bulb's base is compatible with your fixture. Most bathroom fan light combo fixtures use an Edison screw base (E26 or E27).
- Wattage: Choose a bulb with the same wattage as the one you're replacing to avoid overloading the fixture.
- Light Color: Bulbs are available in different color temperatures, from warm white to daylight. Choose a color temperature that suits your bathroom's decor and your personal preference.
- Lumen Output: Lumen is a measure of the amount of light a bulb emits. A higher lumen output means brighter light.
