Long Run Rechargeable Light?

[Gemster]

I need a lamp/light that has a long run time and either is rechargable or uses 18650 battery (ies) to leave in our gas grill to deter mice at night.
Long run time on a charge is more important than high output for this use.
Any ideas?

Easy! Streamlight 2020 Stinger set to low.

I am not sure if incand. 2x18650 with 3 hours run time is what you looking for.
