For once, here it comes dune lightweight tablet (200g) that looks like a reading light. Easily transportable, it is protected by a transport bag Felt and slips relatively easily into any bag, but It will also include cable and plug and detachable foot, which ends up being cumbersome.
Once installed, it gives off a pleasant light, pure and strong, which probably also explains why this type of material nest unfortunately not on battery.
A lusage, this seems efficient, but i was quickly annoyed by cable length constraints (too short), distance between the tablet and the face and still transmission constraints. The low price certainly justifies these drawbacks.
In conclusion: far from perfect but ideal for testing such equipment or to finally install it once and for all somewhere once lon found good provision
