I have an Igaro and a Dynamo, on our next trip we don't really need lumens, just a ride to the restaurant and back set up.
Aldi 196 lumens £7 seems to tick a box. In stock now.
Charging lights suggest it charges when lit.
Otherwise it claims 3 hours of light via USB.
Mebbe worth a look.
Cheap dynamo USB charging lights.
