R50-D model remote control with brightness adjustment function, made by IRIS OHYAMA. I am selling this because I replaced it with a new one! There are no noticeable stains, but it has been used. Since I don't have the light unit itself, I haven't been able to confirm its functionality thoroughly. The infrared sensor lit up red, so I think it still works! Batteries not included! - Brand: IRIS OHYAMA - Model: R50-D - Functions: Brightness adjustment, switch - Battery type: Uses 2 AAA batteries - Country of manufacture: China Thank you for viewing.
