The lighting industry can be awash with terminology, acronyms and words that simply can confuse even the savviest of clients.
To help, we’ve popped together a few terms we know the average lighting survey will use, including our own free lighting surveys, and a few you may find across lighting websites like ours.
|LED||Light emitting diodes. The ‘illuminating’ element of modern lighting|
|HID||High intensity discharge lamps. Traditional box or dome lights found in factories and street lighting.|

|lm||Lumens. The true measure of light output.|
|W||Watts. The amount of energy consumed to power the ‘light’. Traditionally, but wrongly, used to measure the level of light.|
