Richard... Nah. You got me beat!

The water's warmer. The guys aren't wearing wetsuits. And the camera doesn't get submerged.

You got some cool footage!

The Microbeam 128 doesn't get hot under normal shooting conditions: on for a few minutes, then off for much longer. But if it's on at max power the whole time, then it's going to need some ventilation.

I know Richard A. did not intend for this purpose, but I have used my Coollights LED 256 as an on camera light with an HMC-150 and it was great.

Cool Tim, do you have a picture of how you mounted it? In other words, on hot shoe or on an arm?

Hey Richard.

I have a little hotshoe adapter with a 1/4-20 threaded swivel post, much like what comes with the LED 256 for mounting on a light stand.

This light is no heavier than my Lowel ID light I used to use for on-camera lighting and I do not need a battery belt!
