So I made a comparison video (below), but before you begin watching I want to clarify a few things. This test is nowhere near scientific when it comes to measuring CRI or Color accuracy, but it should be somewhat helpful when it comes to measuring the amount of light at a distance. Another thing I want to clear up is that this is not by any means a fair comparison as the CAME-TV 55w Boltzen LED Fresnel Light (found here) is measured with a Fresnel Lens while the Aputure COB120T (found here) was working bare.
By performing this test in this manner, hopefully it shows that a smaller light with less power can still be capable of outputting a decent amount of light at a distance over a more powerful light. Especially within the last few years, with cameras (i.e. Sony A7s, A7sII) that have better low light sensitivity, we can shoot with less powerful lighting kits. Ok, let's get to the video.
I would not say one light should be considered as a replacement over the other. There are major differences in size, weight, power, function, and price - two different types of lights. I would say having both the Aputure COB120T and CAME-TV Boltzen 55w Fresnels as part of your lighting kits can be beneficial!
Over the next few weeks, I'll be gathering more footage of these lights in actual use and putting up a more official review. But because I know brightness tests like these are what most people need to decide if the new 55w Boltzen LED Fresnels is something to consider, I wanted to at least get this basic test out there.
