The LS-150, the successor to the Luminance Meter LS-100, is a highly accurate and easy-to-use luminance meter that conforms to the DIN 5032-7 Class B standards. It has a wide luminance measurement range, from as low as 0.001 cd/m² to as high as 999,900 cd/m², and is suitable for measuring various light sources and reflected light, including road and outdoor signage brightness.

Luminance Meter LS-150

The LS-150 Luminance Meter (successor to the LS-100), with a compact and ergonomic design, is a highly accurate luminance meter equipped with a spectral response that closely matches the V(λ) spectral luminous efficiency function of the human eye, providing measurement results that correlate with visual evaluation.

Featuring a single lens reflex (SLR) optics system, the LS-150 provides precise targeting control, even at close proximity. The viewfinder displays the exact area to be measured, and when used with optional close-up lenses, it can accurately measure areas as small as 1.3mm in diameter. The measured luminance value is conveniently displayed both inside the viewfinder and on the external monochrome display of LS-150.

The LS-150 meets the standards of DIN 5032-7 Class B and has a wide luminance measurement range, from as low as 0.001 cd/m² to as high as 999,900 cd/m². Additionally, it offers color correction and calibration functions, allowing users to select a standard luminance and correct any differences based on specified light sources.
