Very practical for professional use as it comes with 3 different lights. Cold light, warm light and warm/cold, and these 3 you can scale down or up to many levels. You don't need to assemble it, it's ready to use. The only downside is that it doesn't have a stand, but it does have a phone holder for those doing live makeup, the light is aimed straight at your face as the phone is in the center of the ring.
