I have 2:
Deben Tristar Pro LED (lamp only and bought chinese Lithium battery, total cost £70-80), mounted on the scope, battery in a stock/cheek piece.
Deben Tracer, internal C123 batteries - good for the 75yds you will be plinking with a .22 but only without the red filter. with the red filter it will barely make 50yds
I use the red filter for everything now. not usually a Deben fan as they are pricey. but they are a lot smaller than the Clulite alternative.
LED run on Lithium is the way forward, light, internal and powerful
