Good choice. I was hesitant to buy a "D" cell Streamlight Siege because of the description specifying alkaline batteries. However, one of the comments I read indicated a Siege owner was using AA rechargeable's inside D cell adaptors, so I bought the Siege and used my 10KmAh rechargeable D cells. The lantern works great, lights up the entire room -- will be very useful for the next power outage.
