You Have Found Enlightenment - In Our Technical Resources Area

Are your bulbs making you incandescent? Are your white LEDs making you see red? Help is at hand - in our technical resource area (we hope you don't mind our awful puns though). Our technical area includes a handy guide to units and a glossary of terms to help you to navigate your way through the jargon used in photometry and light measurements. We also post regular updates to our Talking Photometry Tech Blog - articles to help you understand the important metrics used to express the output of LEDs and other light sources. You'll also find the Lighting Magazine "Photometry Focus" articles that Dr gareth John writes  - these review the best-of-the-base in lamps and luminares that we test each month. Still in the dark? Simply use our Enquiry Form to submit your light measurement question and we will endeavour to illuminate you.
