This is a brief excerpt from CheesyCam
Ever wonder how your LED light compares to others on the market? 600 LEDs? 1200 LEDs? Adjustable Color Temp? 5600K? CRI? 2200 Lux? Yadda Yadda Yadda… There’s a few dozen LED video lights on the market, but i’m not sure if there are true standards in which they are being tested before the specs are listed on the packaging. Light output can be measured at different distances, and if the rating on the box seems pretty high it’s possible it was tested at a distance of 1 foot while another may have been tested at 4 feet away.
There are just too many variables, so I finally decided to run a few tests of my own in a more standardized fashion. I’m starting out by placing various lights at a distance of 4 feet. I’ll be able to compare the spread (diffusion) of each light with this method. I’ll be using the Sekonic C-500 Color Meter to take a few LUX readings to see which has the highest light output. I’m also able to take color temperature readings and check for color bias (green/magenta cast).
