I'll stop advertising for Bunnings and start to do it for us. You can't get plywood at Camera Electronic, but you can get lenses...
The first light that attracted my eye turns out to be the more expensive alternative - the
Nanlite Forza 200. It's a dedicated LED monolight that resembles an AC studio light, but is powered by a battery. I'll correct that - you can also connect it to AC if desired, but the location shooter will appreciate the battery option.
As a monolight, it can take a series of light modifiers and reflectors - the attachment looks to be Bowens bayonet. You can put soft boxes and grids in front as well as light concentrators. For stills shooters, imagination need not convert what a modelling light might be when a flash goes off - this is a constant light that be the same whatever intensity you set it at.
It is also a cool light and quiet - if you are recording video you need not fear a massive buzz from it.
Note the control section of the back of the power pod - continuously variable intensity as well as dedicated daylight power. A battery or the AC adapter clips into the pod on a V-mount and the whole thing can be kept clamped to the lower level of a light stand, where you can reach it easily.
As far as controlling the light head, I was amused at the angled handle, but realised that some people cannot decide whether it should be vertical and some whether it should be horizontal...so this is a compromise. And the mounting? Standard light stand fittings. Nothing home-built about it - this is for professional use.
Note that the power supply and control box is also built for portability - not every show is in a studio.
