Measuring 117 mm, the C5R is admittedly somewhat bigger that its sister (the P5). On the other hand it's slightly lighter and definitely more powerful. The reason is its  lithium-ion battery, helping it to run for 12 hours. The light can be charged simply using the Floating Charge System. It has three light functions and can fit in a shirt or trouser pocket.

• Performance optimized – Up to 240 meters beam distance with up to 420 lumens of luminous flux
• Long operating time – Up to 15 hours in the lowest setting
• Very convenient charging – Quickly to hand with the Floating Charge System 
• Simple operation – 3 light functions, 1 end cap switch
• For a long lifetime – Robust metal housing and high-quality gold contacts
