The latest light to arrive is from Sanguan, the ST-T2200 has a claimed 2200 lumen out put and 3 hour runtime on full power. Only time will tell if this light matches up to its claims. But initial impressions are good, the build is nice and compact and even comes with a 6cell battery pack. At £95 it's more expensive than your standard Chinese lights, but the build feels better.
Stay tuned for a full review coming soon.
