Our take on the Coast G45

The Coast G45 is a small aluminum penlight that runs on a rechargeable Li-Ion battery or a single AAA, with a fixed high and low setting and a 150-lumen maximum. It weighs about 3.6 oz and measures 4.5 inches, so it clips into a pocket or tool bag without bulk. Its beam reaches roughly 121 feet, which is modest next to larger tactical lights but fine for close work. The dual power option sets it apart from sealed rechargeable penlights: you can top it up or drop in an AAA when it runs dry.

Questions and answers

How long does the battery last?
Coast rates it at about 4 hours on the higher setting and up to 8 hours on low. Expect the shorter end when you use it on high.
Can I use regular AAA batteries?
Yes. It takes one AAA (LR03) as well as its built-in Li-Ion battery, so you can keep it running when the rechargeable cell is empty.
Is it waterproof?
Coast lists it as waterproof, so rain and splashes are not a concern. It is not built as a dive light.
How bright is it compared with other penlights?
At 150 lumens it sits in the middle of the penlight class. It is enough for close work and walking, but not for lighting up a field.

You get the flashlight and its built-in battery. A separate AAA is not included.
