Make those large LED Video Light Panels more portable by running them off of batteries. Here's a random little video showing you how to power up those CN-600 / CN-900 LED Video Lights using the 14V Sony BP-U30/U60 batteries. It's not the cheapest solution, but compared to other batteries available, it's not too shabby.
This was the same battery adapter that I showed earlier which acts to power up your BlackMagic Cinema Camera. You can find the products below.
Remember a short while back I mentioned I was working on a personal project to perform some independent LED Video Light Tests? Well here's a small update on where this project is at.
The image below (computer screen shot) are various different LED video lights I have laying around shot with exactly the same settings. This is a visual reference to compare the brightness, spread (diffusion), and also color reference of each LED video light. I've locked the camera down to a white balance of 5600K for these images. Some of the tests were performed between Daylight and Tungsten, but the side by side comparison really shows extreme color casts between the various LED lights.
I also decided to get more serious about using a true LED Spectrometer for these tests that will provide me with more accurate readings and charts. I'll be able to share these images as well as exact numbers from the meter for each light including CRI and LUX readings. The image below are a few settings from the various LED Video lights. This project will be quite interesting indeed..
[Note:] I am performing my own tests with a standardized setup across each LED light as a reference. This is an independent test which may greatly differ from what each Manfacturer displays as their proper listed technical specifications.
Each Sony NPF style camcorder battery runs at 7.4V. By running them in series, it works at 14.8V which is the minimum power required for the 600 and 900 LED light panels at full brightness. I took two basic Sony NPF battery chargers, gutted them, and then wired them in Series to provide 14.8V DC.
Remove two screws under the rear sticker and then pry apart case
To wire up the cases for Series, basically you take the Negative wire from one and the Positive wire from the other and connect them to the barrel plug. The other two wires (negative and positive) from each charger would be connected together.
Sorry for poor diagram
Next I added a bit of extended wire and used my Barrel Plug (shown here) to connect directly to the LED light. The Barrel Connector is super easy to work with (no soldering), and is clearly marked with + and - for positive / negative placement. It's a very simple and cheap DIY to provide portable power for these large LED panels. If you want use heavier batteries, just make the wiring longer and mount to your light stand.
[Disclaimer] Attempt this DIY at your own risk. Using your batteries in other ways than intended may cause premature failure of your batteries, or damage.
I actually had no clue these were out of stock, but thanks for the emails and information that they are available again. For anyone waiting on these to come back to stock, here they are. As a reminder, only the 600 and the 900's I have can fit into travel size 'Carry On' airplane roller (not the 1200s). The 600 & 900 have the optional V-Mount battery plate so they can be used remotely and the 1200s don't have that option.
