This is a very old, hand held lantern. It comes with a power cord. The original instruction booklet is still hanging from the handle. It's a model 165, and it runs on AC, or on two Z-46, 69 volt batteries. It works well with the AC cord. The fluorescent tube is in good condition. The battery compartment is a bit rusty inside. The type of battery it uses is not being made any more. The outside of this unit still looks great.
