Sekonic SpeedMaster L-858D-U
Sekonic SpeedMaster L-858D is the
The most innovative, accurate and flexible multi-purpose lighting tool.
The Sekonic SpeedMaster L-858D combines more than 70 years of Sekonic innovation with cutting-edge, light meter design to bring you the most accurate, easy-to-use, innovative, and flexible hand-held device to meet any lighting demand. Incorporating a 1°-degree spot metering system with illuminated viewfinder display, the SpeedMaster L-858D provides luminance measurements without ever taking your eye off the light source. In addition, a built-in retractable and rotating Lumisphere offers illuminance measurements even in tight spots, all in one meter.
As you would expect, units of measurements are selectable from luminance foot-lambert (fl) to cd/m2 and illuminance foot-candle (fc) to lux (lx) respectively. However, the SpeedMaster L-858D doesn’t stop there, it incorporates an extensive array of measuring functions to meter every light source’s brightness and lighting ratio. Providing up to 20 different measuring modes, the SpeedMaster L-858D meets and exceeds the expectations of demanding lighting engineers and field evaluations technicians. With its flexible multi-function capabilities, the SpeedMaster L-858D measures ambient light, as well as flash bursts such as traffic camera systems, industrial, manufacturing, and scientific applications. Critical flash data required for calculating the effects of ambientflash conditions are easily displayed simultaneously while taking a measurement. As its name implies, the peedMaster L-858D also measures brief flash burst for precision flash duration calculations. In addition, the SpeedMaster L-858D is loaded with Photo, Video and Cinema features and functions to meet and exceed every lighting condition. All weather design, wireless triggering (with optional radio transmitter), utility software and optional accessories all add to an incredible measuring tool in the palm of your hand.
The ultimate multi-function luminance and illuminance monitor.
