Came-TV Boltzen 55w LED Zoom vs Arri 650w Fresnel

Focusable LED Battery Powered video light. This is a very affordable good option compared to a Dedolight. Works on FP Sony type batteries and can also run on AC power. Everything is included in the 2 piece kit, even a plastic case to travel. I tested it at 4800K instead of the advertised 5600K. All the LEDs I have tested usually run around 4500k to 4800k. The only one I have used so far that really runs at the advertised color is the KinoFlo Celeb. I assume the Arri LEDs should also run like a Kino.

Here are some shots of the Boltzen kit:

 

Below, we have a shot comparing sunlight coming from the window on top left and the Boltzen with a gel at 3400K.

In the next section I compared the Boltzen with an Arri 650w Fresnel. First thing to notice is the Boltzen is rated at 5600K while the Arri is at 3200K. Both units can run in Flood or Spot. The intensity of both units is very similar from .5 a stop to 1 full stop in luminosity. For example, at 9ft projected to a wall we measured the following:

Boltzen – Spot: 16EV        Flood: 15.5EV

Arri 650w – Spot: 17EV         Flood:16EV

Here are some shots of those two.

So, I see when LED technology can really replace traditional tungsten lighting now at much better prices. Those Boltzen are $288 USD each at B&H. The Arri 650w Fresnel is $484 USD.

Something to keep in mind, the Arri is very neutral for 3200K while the Boltzen will need some Gels to get it closer to 5600K and no tint shift to green or magenta, which will decrease the intensity of the light. In the same line, the Arri would require CTB in order to achieve 5600K in case you wanted to work in that spectrum. In all, I would still go with the Boltzen for its price, relative low heat components, performance and compactness.

As a final note, I’ve read some people are afraid of the built in fan on the Boltzen lights, well…  the AC vents in your studio are louder. The fan on a Red Epic Dragon Camera is louder as well.
