The Coast Polysteel 400R is a rechargeable version of the popular Polysteel 400 and offers an output of 380 lumens or 400 lumens depending on the battery type.
The dual power system means that it can be powered by the rechargeable lithium-ion battery pack which is more economical in the long run or it can use four non-rechargeable AAA alkaline batteries which is perfect as a back up if you run out of charge and are away from a power source.
The lithium-ion battery pack features a micro USB port so that it can be charged using the included USB cable via a computer or using the included mains/car charger. While charging is in progress and LED indicator glows red and turns green once charging is complete. The battery pack also features a standard USB port and can be used as a power bank to charge external devices.
It features a stainless steel core that protects the inner components, meaning the Polysteel 400R is impact resistant up to a 3 metre drop height. The outer casing is made of lightweight polymer, displaying a comfortable non-slip grip design.
A half press of the tactical tail switch from off cycles through the three brightness levels, high, mid and low, giving you the option to choose the right level for your application.
Using Coast's Pure Beam Focusing Optic System the bulls-eye spot beam provides a beam range of up to 202 metres, and the ultra view flood beam gives a consistent circle of light with no dark circles in the middle. Changing between spot to flood is achieved using the twist focus control in the head of the Polysteel 400R.
The Polysteel 400R is fully waterproof to IPX8 standards up to a depth of 3 metres for 6 hours.
