Sometimes, you need a headlamp. All Light-Belt devices use holder clips that allow the light unit to be easily shared. Rather than buying a headlamp, you can simply clip the Light-Belt light into the LB-HB headband. The LB-HB is compatible with both the LB1 and LB2 lights. The LB1 and LB2 lights are sold separately and not included with the purchase of the LB-HB.
