Length of ultra light arms on Gates housing

[globaldiver]

I am planning to buy "Ultra-Light" light arms to my Gates PD-170 housing. I will initially use the two 10W HID UK light cannons that I already have.
Is the 12" length of the arms the best way to go, or does anyone have some good advice regarding this subject?

One of the main reasons to use longer arms for strobe lights is avoid or minimize backscatter. With video lights the light intensity is a lot less than for strobes. Backscatter becomes more or less a non problem unless theres really alot of particles in the water. I'm using 2 10 watt HIDs with my Gate PC330. The light heads are mounted on top of the handles on a very short extension. I always get good lighting unless its REALLY filthy. Depending on your beam width, you may want to separate them a little for wide angle shots.

So the 12" arms would probably be enough then. I am using the housing in OW for the first time this coming Sunday, and will try the 12" arms to evaluate the results.

Thanks

Two Ultralight 8" arms with adapters and clamps purchased today. After closer consideration I opted for the 8" arms instead of the longer 12". This system is going to fit perfectly.

Thanks for all your advice and input.

Sincerely
