A Guide To Using the Relative Irradiance Mode on Your Ocean Optics Spectrometer

 Nov 2011:  Every Ocean Optics spectrometer has what is called an “instrument response function”, or IRF.  The IRF refers to how much the spectrometer responds to light across its wavelength range.

A Guide To Colour Temperature: Are Your Whites Giving You The Blues?

August 2011:  Even though two white LEDs have the same CCT (correlated colour temperature) they can look very different. Understand how two LEDs with the same colour temperature can look markedly different, by reading our guide...

Driving a Calibration Lamp

A Guide To: Driving Your Calibration Lamp

August 2011:  The output of the lamp that you rely upon to calibrate your light measurement equipment is critically dependent upon the exact curent that you drive it at. Our guide explains why ...

Colour Rendering

A Guide To: Colour Rendering

August 2011:  The colour rendering index (CRI), is a quantitative measure of the ability of a light source to reproduce the colours of various objects faithfully in comparison with an ideal or natural light source.

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. » More

Sheer Lumenancy

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. » More

Hard Talk

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. » More

Selfridges Store Birmingham

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 walls have a blue tint, hence the building appears pink. This is a perfect illustration of the problems that lighting designers have with colour rendering. » More

Bentley

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. » More 

Headlight

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. » More
