This is a place where primarily we work to create the future of light for medical environments.

What is the optimal light for a medical environment?
What light can accurately illuminate the surgical field?
What light is gentle on health care providers' eyes, and can soothe patients' nerves?
These are the questions we, Yamada Shadowless Lamps, wrestle with.
We hope to continue to feel, describe, think about, and above all make the future of light for medical environments.
It is that hope that gave rise to the Medical Lighting Lab. (MLL).
