I’m going to use the meter setting of ISO 800 and 1/60 sec because it’s an old meter so it doesn’t have 1/50 second on it. The distance of the meter is going to be 8ft, 12ft, and 16ft and we’ll see how the light falls off.
I went to Wooden Nickel Lighting to shoot this test and it’s a great place to check out all sorts of lighting equipment you might need for a shoot.
The reason I chose a Tungsten 1k as my first measurement is because it’s a light I’m used to working with and it’s a great base to start from. I’m starting first with a 1K flooded because once you turn it into a spotlight it just turns into a whole another animal. We aren’t putting any type of focusing devices on any of these lights, so they are just open.

So we have the results of the test below, the 1k flood at 8ft is f8.7, but when I go to the HMI 1200 it ends up being 4 stops brighter than that at f64.2. A Joker 800 is 5 stops brighter than a 1k flood.
If I go to a Lightpanels Astra 6x Bicolor, those are very powerful lights and they shine at .1 stop brighter than our 1k standard. They aren’t diffused at all and shine about the same as a 1k.
I’ve used a silk light from Rosco for a long time, and it performed the same as the Kino Flo Freestyle 21. These are diffused soft LEDs that are used as is right out of the box.
Lite Mats
Now we are going to switch to our Lite Mats. Checking out the Litegear LiteMat+ Plus 2 it was -2 stops off a flooded 1k. Even though this is an LED light without any diffusion, it wasn’t as bright as I thought it would be.
Single LED Bulb
Now we move onto our single LED with a Bowens mount category! We have first up the Aputure Light Storm 300D, which was -.5 stop under a 1k. The Aputure Light Storm C120D G1 was -1.6 under a 1k.
