Here's a product overview on the new Boltzen 55w and 30w LED Fresnel Video lights. What they come with, a run through some of the features, and few samples with Flood, Spot, and without the fresnel lens. Anyone working with hard spots like the Lowel Pro Lights, should really find these lights a joy.
The Boltzen 55w and 30w LED Fresnels are compact yet put out a good amount of power and the Fresnel lens has strong output even at a distance. The lights can be battery powered and stay cool to the touch (unlike pro lights), and you don't have to worry about fragile halogen bulbs burning out or breaking. You can use the lights without the fresnel lens for wider throw.
Keep in mind there are two things not seen in this video. First I didn't show the D-Tap cable which allows you to power these lights off of your V-Mount or Gold Mount batteries. They recently just added this D-tap Power cable as part of the standard kit, so anyone ordering one may have it in their case. Second is the Wifi control. There is a port on the back to which you will attach a wifi dongle. Then you can control it through a remote (or possibly iPhone app). This (optional) part was also not available yet during the making of this video.
If you're on a budget or super concerned about fan noise, the 30w is a great option. But personally I think the 55w is the way to go. The fan is barely audible from a short distance away. They 30w and 55w both share the same size. At this moment I think CAME-TV may be offering the smallest 55w LED Fresnel under $300 (cheaper when buying sets). I find these could be a perfect little compact hard light to keep in your kit.
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.
