Yes, very useful, especially for "older" eyes. Mine has fluorescent lights with two different intensities. It has two articulation points and a good magnifying lens. It can be clamped to a work surface or fixed to a wall or bench with three substantial screws as it is rather solid and heavy (watch your head!). They can be often seen for sale at modelling exhibitions.
I bought mine here in France.
However, I was intrigued by the small "cover" which is removable and is simply placed on top of the lens when the equipment is not in use. I thought it was just to keep dust off the lens. Then, one day, I had left it uncovered and saw that the sun coming in the window was being focused onto my bench....which was VERY hot at that spot. If there had been anything more immediately inflamable than my bench I think a fire would have started, readily. So, be warned.
Roger in France.
