A 100 watt halogen bulb is a type of incandescent bulb that uses halogen gas to increase efficiency and lifespan. From my experience, these bulbs give off a bright, crisp light that’s great for both indoor and outdoor use.

- Brightness (Lumens): The brightness of a 100 watt halogen bulb is typically around 1600-1700 lumens. I checked this to ensure it would light up my room adequately.
- Base Type: Make sure you know your fixture’s base type. I needed an E26 base for my lamp, so I double-checked this before buying.

- Lifespan: Halogen bulbs generally last longer than traditional incandescent bulbs. The 100 watt variety I bought promised around 2,000 to 4,000 hours, which felt reasonable for the price.

- Bathroom vanity lights
They create a bright, natural light that’s flattering and practical.
