I bought this for work, but I'm selling it because I haven't had a chance to use it. I have confirmed that it powers on, but I haven't used it otherwise. I will also include the AC adapter that I purchased at the same time. The light cost around 20,000 yen, and the adapter was about 3,000 yen. This is a high-intensity LED spotlight with an arm, resistant to water and oil, and suitable for harsh environments. The large arm makes it convenient to illuminate the appropriate area during work.
