This is a remote control for a KOIZUMI fluorescent light ceiling light (made in 2011). I am selling it because I replaced the light fixture. - Brand: KOIZUMI - Model Name: KRU-MRH-7C1 - Batteries: Requires 2 AA batteries (not included) There may be scratches and stains that are not visible in the photos. Please be aware that returns cannot be accepted for such reasons. It has discolored due to aging, but the operation has been confirmed. This is a used item, so there is no warranty. Please understand this before purchasing. ※ The remote control and adapter for one of the two light fixtures are being sold separately. If you need the main unit, the other one is listed separately, so please check it out.
