The PD35 is a great option.

Another to consider, within the same price range is the 780 lumen Foursevens QT2L-X. This one has the output level selected by loosening or tightening the head. When the head is tight, it always outputs the amount of light programmed. The turn-on brightness level can be selected, by tightening or loosening the head, while the light is turned off, so it will turn on at the desired level.

Thanks to a suit from Surefire, they're discontinued, but still readily available.
