Japanese-based Fuji Toki says that its new ZX-S330 Extreme is the most powerful LED light in its ZEXUS Series. Boasting 200 lumens of brightness, it also features a rear recognition light that can be illuminated in different colours. It has a smart control facility that allows the brightness to be memory-controlled by using the main LED switch. Powered by three AA alkaline batteries – sold separately – on main LED high mode, the user will get 15 hours of light. The battery lasts for 400 hours using the rear recognition light continuously..
