NOT 100 hour battery!
For me it lasts for like 2.5-3 hours! ( half an hour a day, 5-6 days). And that's disconnecting battery from light every time after use. If you keep it connected all the time, it will bleed charge and will be empty in like 2 days tops.
Light levels are actually decent enough.
However there's another huge negative part - the connector between battery and light itself. it fits quite well together and therefore can be a struggle to disconnect it almost every time. You WILL break it very quickly.
