Pros (Why They’re a Strong Choice)
- Ambient Lighting: Because the light comes out on all 4 sides, it provides a nicely distributed soft glow — great for deck posts without being overly harsh.
- High Quality Build: The aluminum construction means these caps are very durable; they don’t rot, crack, or corrode easily.
- Energy Efficient: Low-voltage LED means low power consumption, and the warm 3200K light is pleasant.
- Weather Resistance: Rated to handle rain, salt air, and general outdoor exposure — very suitable for a coastal environment.
- Aesthetic Appeal: The pyramid shape is classic and suits many deck / railing styles.
- Long Life: With good build quality and warranty, they should last a long time, reducing the need for frequent replacement.
