IKEA makes a small gooseneck LED lamp called “Jansjo” that I put beside my turntable.
Turntable cuing light
I was looking for a solution to cuing records in dim light and found a cheap effective light. It is a BBQ light for around $13 at Amazon that has three AAA batteries, 24 inch gooseneck and clamps to the rack. It looks good and so far does the trick! I didn’t want another wall wart in the system so the battery option seemed like the way to go.
