Each pack contains four 31mm (1.22 inch) bulbs rated at about 400 lumens per bulb (640 lm per pair when measured as pairs), designed specifically to replace common OEM codes such as DE3175, DE3021, 6428 and 6430. These bulbs use high-power 3030 SMD chips and an aluminum heatsink to manage temperature and maintain consistent light output.\u003c\/p\u003e\n\n\u003ch3\u003eHow much brighter and whiter is this LED compared to halogen festoons?\u003c\/h3\u003e\n\u003cp\u003eThe LASFIT 31mm festoon LEDs are significantly brighter and have a clean xenon-white 6000K color that improves interior visibility and creates a modern look.
