How much light from a Kino 4 bank?

[HomerS3]

Here is an question I am currently confronting.

How much light can I expect from a 4 foot 4 bank of Kino Flos. I am currently gearing up for my next short and will be acquiring all my lighting on my own. I love the look I've had with Kinos in the past (when I could afford a gaffer, not this time!) but am trying to discern how many banks I truly need.

I am lighting an apartment daytime interior. Nothing fancy. Imagine a 20 x 20 space with light colored walls.

With a 4' 4 bank am I blasting a ton of light or should I consider another bank to combine as my key?

What's my tungsten equivalent as far as light intensity. (comparable to a 1k? 650?)


Thanks guys. You're saving me an extra rental day to discover the answer to my question. I appreciate any help!

Go look at any flourescent lights and that's pretty much what you get with a Kino. They don't throw very far. The look you are after determines the amount of lights you'll need. If you're going for a high key [bright] look then you'll need enough to lighting to fill up the environment. If you're going for a low key [contrast: shadow & light] then you'll need less. If you want to mix Kino with day light you'll need to use the 5600k bulbs. If you're using typical flouros, they can cause a flicker [might want to run some test to see if they'll work for you] and they will need to be color corrected at the fixture using minus green to bring them up the daylight temp. This also cuts down on the throw because of transmisssion loss caused by the gel material.

Tungsten has nothing to do with intensity. A tungsten light can be a PAR that has pretty good throw, i.e., a car headlight, or it could be a Fresnel and give a even portrait quality light with less throw yet have the same wattage as the PAR.

Flouro/Kinos have built in diffusion coating the inside of the tube so the light travels less distance but is soft and wraps nicely.
