We’re recruiting!

Bentham is growing and we are looking to recruit the following key roles at our Reading offices.

FDA recognition of ANSI Z80.36-2016 – Ophthalmic Instruments

Up until now, the FDA recognised ISO 15004-2: 2007 for the evaluation of light hazard associated with ophthalmic instruments including direct and indirect opthalmoscopes, slit lamps, fundus cameras, endoilluminators, and operation microscopes for ocular surgery. From March 31, 2018, declarations of conformity must be made with reference to ANSI Z80.36-2016.

SCHEER: Are LEDs safe?

The European Commission and SCHEER (the Scientific Committee on Health, Environmental and Emerging Risks) have recently published a Preliminary Opinion assessing the potential health risks associated with LED emissions in the general population.

IEC embraces multi-junction PV devices

The IEC has added to its 60904 series a new standard, IEC 60904-8-1:2017, "Photovoltaic devices - Part 8-1: Measurement of spectral responsivity of multi-junction photovoltaic (PV) devices". This provides important information on...

Bye-bye CRI?

The CIE Colour Rendering Index (CRI) (CIE 13.3-1995) and the general colour rendering index, Ra, has for many years been the standard metric for the colour rendition performance of light sources, included in a wide array of...

The IEC addresses characterisation of the blue light hazard

Researchers around the world have raised concerns about the safety of LED lighting on a regular basis, with focus ranging from the impact of blue light to issues such as disability glare. In a multipart series of articles that...

Introduction to IEC TR 62778 (LS16 Poster and Presentation)

Driven by the desire to circumvent issues encountered in applying IEC/EN 62471, and to reduce the measurement burden of luminaire manufacturers, a new approach to the evaluation of the photobiological safety of luminaires is now...

Photobiological Safety of Lamps - History and Overview of Standards

Whilst the potential hazards associated with optical radiation have been long understood, up until recently, consideration of this has been mainly limited to a number of specific applications using intrinsically harmful lamps,...
