sorry – I have been away from this thread. The Unit comes in 3, 6 and 8 LED variations, costing £45.00 GBP, £70.00 GBP and £100.00 GBP respectively.
An advantage is that the white balance is set at K5600, so you can get daylight effect and truer colour.
I have the 8 LED version and I am finding that this can cast light much further and more evenly over my gaming table. For close up work, such as photographing say small dioramas or e-bay items, it is much more power than needed and I have it set to level 2 (out of 4) with a diffuser filter on the front (provided), so a smaller unit would do just as well for those type of shots.
I am finding that for indoor shots, it has replaced my flash cube.
The battery life is also pretty amazing. It charges of a USB and my manual says that depending on lighting strength, I can use it for between 1 and 3 hours off one charge. I have have only charged mine once and it didn't need it really, so I wouldn't dispute those figures.
