When I went shopping for my halogen bulbs, I made sure to consider the following features:
- Lifespan: I looked for bulbs that offer a lifespan of around 2,000 hours or more. This means fewer replacements and less hassle.
- Lumens: A higher lumen rating ensures brighter light. I aimed for bulbs that provide at least 300 lumens.
- Base Type: Understanding the base type was crucial since I needed bulbs that would fit perfectly in my fixtures. Common bases include GU4 and GY6.35.
- Dimmability: If you prefer adjustable brightness like I do, I made sure to find bulbs that are compatible with dimmer switches.
- Color Temperature: I considered the color temperature measured in Kelvins (K). For a warm, inviting glow, I opted for bulbs in the range of 2700K to 3000K.
