Bentham’s ISR300-PSL spectroradiometer is an essential tool for accurately assessing the blue light hazard across a wide variety of lighting products.

CE marking of luminaires based on the EU low voltage directive 2014/35/EU needs execution of the EN 60598-1 standard according to which the assessment of blue light hazard must be conducted with reference to IEC TR 6278. The ISR300-PSL offers the luminaire manufacturer the most accurate and dependable direct assessment of blue light hazard, without extremely conservative assessment results generated by using a technique based on calculation and estimation.
