Picked up one of these, cheap as chips £5.35 delivered.
Its a 20cm ring light, white, warm white and a blue tint, well adjustable. Tripod base you can attach the lamp to or attach to included selfie stick and screw to base and it will extent up to about 1.3m. Inline remote for the lamp and a separate blutooth camera shutter button. USB powered and runs between 5w and 12w.
Its actually very bright on full power, would very easily light up a room or large tent, I'm using it in the mancave as a floor standing lamp next to worktop. Comes flat packed in 21cm X 2cm box so very easy to store.
As they only costs about a pint and a half each I've ordered another three which I'll store away. Ebay item 265597894145
