Its all 12 or none at all Fred, which as I said, might not be appropriate if you are stalking bass in the dark (which I don't). It all depends on what you want it for.
I use mine on promenades/piers with it switched on all the time. It also doubles up as an emergency back up to a 'proper' headlamp on the rocks.
Being very small, it easily slips into the tackle bag without taking up valuable room reserved for flask and chocolate bars so I always carry it
There are better LEDs about (more expensive as ABM says, and multiple option as to 1/3/7 bulbs etc) but for £6 you can't go wrong. Even if you don't like it for fishing you will still find a use. I keep one in the car glove box.
