LED lights usually are brighter than HID lights because they have a higher lumen capacity. LED lights can have a brightness of up to 9,000-10,000 lumens, whereas HID usually only ranges up to 8,000 lumens. It is said that HID lights tend to be brighter for things like headlights on cars, but the brightness is often a product of the reflector and lens and how the light emits across an area. LED lights are more common for headlamps and are longer lasting and more durable than HID.
