Yes, the lamp comes with a mirror as part of the included accessories. The package includes the SL-480 ring light, light stand, power adapter and cable, mini ball head, smartphone holder with gooseneck, mirror, and a bag. This is confirmed by the official product description and scope of delivery details.

No without.

Hey, Orgonaut, unfortunately I have no idea. But the light is definitely very strong, I am satisfied with it.

For ring lights and the like, lamp tripods with spigots are needed. They do not fit on camera tripods.

A lamp tripod with spigot is required.

Hello Felix I don't know what a flash head is either. But yes, the lamp is permanently lit. As I see it, you can't change that either - only light colour and intensity are adjustable. Kind regards David
