Test Methods for Solid State Lighting

Octobert 2009: Pro-Lite was invited to give a talk on testing solid state lighting (SSL) at the Ultra Efficient Lighting seminar held during the Photonex exhibition. The talk reviewed the IES LM 79 standard which defines best practice for testing SSL.

Watts Wrong with the Lumen?

May 2009: "Sheer Lumenacy - EU to replace watts with continental lumens". The Daily Mail considers the planned change in the labelling of light bulbs which will soon be specified according to the light they emit rather than the power they consume. No more convoluted explanations which correlate the output of a 12 Watt compact fluorescent with a 60 Watt incandescent bulb. Both emit 800 lumens. Simple. Great headline, though.

Hard Talk: a Measure of Free Trade

February 2009: Pro-Lite was invited to write the Hard Talk column for the February/March 2009 issue of Electro Optics magazine. We chose as our theme the importance in business of sharing specifications in an unambiguous way and the problems that can occur when this doesn't happen. It all started off with a chap called Napoleon Bonapart, apparently.

The Mail (Doesn't) See Red

April 2008: The Daily Mail saw red at the apparent lack of patriotism of the Selfridges store in Birmingham. At night, it is normally illuminated in blue, or other hues to mark special occasions. The Mail felt that the building should be illuminated in red to mark St George’s Day. The building can indeed be illuminated with red, but the wall tiles have a slight blue tint, hence the building appears pink. This is a perfect illustration of the problems that lighting designers have with colour rendering.

Helping Bentley to Make the Best Better

August 2008: Bentley chose Pro-Lite to supply a ProMetric CCD imaging photometer to help in the development of its cars’ interior and exterior lighting, instrument panels and infotainment displays. ProMetric photometers are powerful, CCD-based light and colour measurement instruments that provide for vastly increased productivity compared with traditional “spot” photometers.

Helping Ring to See the Light

August 2008: Ring Automotive Ltd needed a way of measuring the performance of their car headlamp bulbs. Traditionally, the illumination performance of a headlamp has been determined using a goniophotometer, but this was just too slow and expensive for Ring. Instead, Ring turned to Pro-Lite for a more productive solution. This took the form of a ProMetric CCD imaging photometer which can measure millions of angles simultaneously.
