Re: Lamp for Canon WP-DC54 housing
I'd say you could do a hot/cold shot to ball mount (products are available), but that seems to me to be a little bit limited, and possibly risky to the housing mount. I have mine on a big rig on one of the posts and a clamp. I can rotate and lean it a bit - though I must say I normally just have it pointing straight ahead. But there are times I have the camera pointed sideways and the light pointed straight to light my way.
I'd rather have it on the end of a flex arm of some type for the added capability (flexibility of positioning).
By the way, I've only had two focus lights ever, the first in 2015. I had a Fishlite V24, which gave 2400 lumens of light. The Kraken 3500 gives 3500 lumens. Both had red lights as well, and the Kraken has a blue one. I normally just use the brightest white light - except for battery life.
On the V24, running at full power the light ran about 40 minutes. So I reduced the power on it a lot as I normally do hour long dives. The Kraken is much better. Full power the whole hour. I do then change batteries between dives, so buy a spare no matter what light you get.
The Kraken is around $500 - bright light plus battery life isn't cheap. It's also not really bright enough for video, though it works for macro distances. There are a selection of other lights at various price points here:

If you want to see how mine is mounted, you can pick it out of these images of my rig:
