The Coast XP18R offers an output of 1460 lumens on the highest constant setting, and also offers a momentary turbo output of 3650 lumens.
The dual power system means that it can be powered by the included Coast 'Zithion-X' customised rechargeable lithium-ion battery which is more economical in the long run, or it can use six non-rechargeable AA alkaline batteries with the included battery carrier that can be swapped out with the Zithion-X battery, which is perfect as a back up if you run out of charge and are away from a power source.
The Zithion-X battery is charged inside the torch via the hidden Pro-Tek charging port built into the tail which can be revealed by twisting just the top section of the tail cap above the red line. Insert the included USB-C to split USB-C/USB-A cable into the charging port of the torch at one end, and the other into a suitable USB power source. While charging is in progress an LED indicator glows red and turns green once charging is complete.
A single press of the tactical tail switch from off cycles through the three brightness levels in the order of mid, high, low and off with each press, giving you the option to choose the right level for your application. The mid output will always be accessed first to give a good initial output that is not too bright or too low. Turbo output can be accessed momentarily by holding the button down. If in any mode for longer than 5 seconds the next press will turn the light off thanks to Coast's easy off technology.
A battery status LED indicator is built into the switch and will illuminate when the torch is turned on to show remaining battery power at the current level. Green indicates that the battery is fully charged, red indicates that the battery needs charging and flashing red indicates the battery is nearly drained and needs to be charged immediately.
Using Coast's Pure Beam Focusing Optic System the beam can be focused between the bulls-eye spot beam with a range of up to 330 metres, and the ultra view flood beam that gives a consistent circle of light with no dark circles in the middle. Changing between spot to flood is achieved by firstly ensuring the head is unlocked by twisting it to the right, and the head can then slide backwards and forwards. Once the desired focus is reached the head can be locked again by twisting to the left.
The XP18R is dust and water resistant to IP54 standards, making it perfect for a variety of outdoor activities. Using the Zithion-X battery pack:
