@jonobie I have a small but efficient work light right next to whatever I'm doing, and that works, but the radius of light is pretty small, and sometimes I have to scoot the lamp right next to what I'm looking at! It's okay for crafting but not for photos.
I had a wonderful large lamp with an immense lampshade, and it still fit on my windowsill and lit up the whole desk and half the room. Then the cats dropped it, and it's no longer sold... 😢
