Two LEHL-450 units are included. One is almost new, and the other was used for three months; the strap was worn out and replaced. This model allows you to remove and charge or replace the rechargeable battery. It has four light colors: white, warm white, UV, and red. One LEHL-250USR unit is included, used for three months; the strap was worn out and replaced. It has three light colors: white, UV, and red. The older LEHL-450 has damage to the angle adjustment part and is fixed with adhesive, so it doesn't move. The light functions as shown in the images. You can still use the battery from the newer LEHL-450 in the older one. These lights cost around 4000 yen each on Amazon, totaling over 10,000 yen, so it's a good deal for LUXXE fans who want to use multi-color lights.
