I have a Sure Light LED 3 in 1 floor lamp with 3 levels of brightness and magnification, runs on electricity or battery. Has strong clamp if you want to attach it to your chair or table. Made by the following

I also use a high power headlamp 3 bulbs and 3 functions one, two or all 3 lights. I find this is really a great headlamp if you need a lot of light, you can tilt it down or up and runs on rechargeable batteries. I found this on Amazon. I turn it off, if I am talking to someone, it is very very bright, but truly a good investment for sewing.
