So I bought one of these TAZ 2000. Haven't ridden it yet. Charging with a 3.4 amp USB charger... took a little over 4 hours... first charge. Light was hot during charging, but not unlike other batteries on a charger. Light is BRIGHT. wide beam with long spot... two spots really. Also has white light compare to my L&M Urban 700... that one has green tint to it.
