The lamp uses a frosted polycarbonate lens and an aluminum backing plate to spread light softly and manage heat, giving you the equivalent output of about a 50W incandescent bulb while conserving battery or vehicle power. Each pack includes mounting hardware and wire nuts, making it straightforward to upgrade existing fixtures or add new overhead lighting.\u003c\/p\u003e\n\n\u003ch3\u003eHow do the five color temperatures improve onboard lighting?\u003c\/h3\u003e\n\u003cp\u003eHaving five color temperature options (2700K, 3000K, 3500K, 4000K, 5000K) lets you tailor the light to different tasks and times of day. Warm tones create a relaxing atmosphere for evening, while cooler tones enhance visibility for cooking or repairs.
