I have several of the manuevable lights that I used with my machines. I don't want to stick stuff on my vintage machines so this has been my solution. I've found the Stella lights to be the best. They have a bright no shadow type of light. I plan to replace my Ott Lites with Stella lights as the Ott Lites burn out. I got a clamp on one for next to my serger for my birthday. I love these lights. They are pricey but work so well.
I might try the strip lights for my Juki since its in a table and sits were it's hard to get good light on the needle area.
