Arrived today. Just set up one of them for a quick play. Full review will follow on weekend I think.
Impressions are it will do the job. The stands are adequate. Feet aren't adjustable so needs a flat surface. The main shaft has two extendible parts to adjust height.
Light output doesn't feel as bright as I thought, although it is hard to quantify exactly how much relatively it is putting out. I'll have to use my camera as a light meter later. Compared to my house lighting, it feels similar in level but different in colour. I use mostly "energy saving" types, whatever is cheapest available at the time. The house lighting is warmer in colour, with these lights at 5400k seeming cooler in comparison. I will have to use one or the other to save on balance nightmares.
On brightness, if I turn one of these on in addition to house lighting, it doesn't seem to do much. If I turn off the house lighting, everything is a different colour (my eye wb setting is slow to react it seems) but it is similar in level allowing for directionality. If I then put the room lights back on and turn this off, it feels much darker. I think the colour balance might add to the brightness perception somehow.
I suspect the light level might not be as much as hoped for two reasons: the bulb is an energy saver type, and the incandescent equivalent rating always seems far too optimistic. Also there are two layers of diffusing in the light box, so that probably has an impact on usable level too. That's something else to test (with and without diffusers).
I need to get the 2nd one set up now. Should have a pair of new subjects tomorrow to test it on
