This is a high-output LED light. When shining it from outside a window, it turns night into day. I run a small photography studio and don't use it much, so I'm selling it. ■ Product Features M600D: A powerful daylight-type high-output LED light with a power consumption of 740W. It boasts an overwhelming illuminance of 15,700 lux at 3 meters when the included professional reflector is attached. The dimming curve can be selected from four options: linear, S-curve, exponential, and logarithmic, each with its own output for various settings and applications. Power can be supplied via AC power or V-mount batteries, and up to two batteries can be attached, allowing for operation suited to the usage environment. High color rendering with CRI96 and TLCI97. Bowens mount is adopted for the front mount. Control can be selected from four types: body operation, the separately sold RC-A6 remote control, DMX, and smartphone app. In silent mode, although the light output is limited, it can be used silently by stopping the cooling fan. FLS10 Fresnel: A Fresnel lens that can be attached to the M600D to narrow the beam angle from 35 degrees to 10 degrees. ■ Product Name, Price, and JAN Code KNOWLED M600D LED Light ¥248,000 Manufacturer Promotion ↓ https://youtu.be/3XXxuiwQ8-g?si=CfgBaENbaQAFu9XY
