The COAST PS100 is made with COAST’s famous Polysteel construction. The heat-welded poly coating covers a stainless-steel core to protect the lighting technology inside, so these lights are proven to be crushproof, drop-proof, and stormproof. The COAST PS100 is designed for anyone who needs a small, very powerful, pocket-sized light that can withstand any condition and do any lighting job you need to be done. The PS100 is fully tested to be dustproof, crushproof, drop-proof, and stormproof. At 110 lumens and powered by 2 X AAA batteries, the very slim PS100 fits nicely in a shirt pocket, safety vest, or pants pocket.
