My brother in law just got me the Black Diamond Spot lamp. It is really sweet. It stays on the setting you are in when you shut if off (single, red or max). It also has a tap function on the side that will change to max brightness. Red setting is a must to preserve night vision.
The 200 lumens are plenty bright for me. I had been using a Princeton that was only 60 lumens. I also carry a high powered flashlight in the boat if needed.
Some guys use the miner type lamps that are too bright in my opinion and cause temporary blindness to others.
