This really depends what is bright for you. You might think that 240 lumens is amazing, or you might think that 1100 lumens is nothing much. I guess i need more info on what you want to do with the light.
Personally, I have a mag 2D in my truck with a dhs heatsink, ssc p4, and a 700mah driver, all running on 2D's. This is a great setup for a backup light that stays in my truck. I use it for general tasks, tonight i used it to get my girlfriends fishing lure out of a tree, and shining for deer on the way out of the fishing spot.
Let us know a budget and a general idea of what you might want, I know that will help us to help you.
