This unit will not operate without the purchase of our Remote Control. (One remote control is all you need for many lights. For event planners we recommend two remote controls.) Battery powered and operated with a remote control, this light features 12 LED bulbs that produce a bright glow to illuminate your lanterns. This wireless lighting is easy to use; simply clip inside the lanterns and turn them all on with one simple click of the remote! These lights include an on/off switch and require 3 AAA batteries (not included). 8+ hours of continuous illumination! Remote is sold separately.
