Installation tips for best results:
- Ensure your fixture supports EX39 Mogul bases and 120-277V operation.
- Use in fixtures that require full-brightness operation, since the bulb is not dimmable.
- Pair with appropriate ventilation in enclosed fixtures to maintain longevity and color consistency.
- Consider spacing and reflector choices in high-ceiling spaces to maximize the 5,000-lumen output and even light distribution.
