I have a Lightforce 170 , I use it with an amber filter , the amber lets more light through than the red, I have taped the edge of the filter to the lamp as you get a lot of light coming back through the edge of the filter ,I bought extra scope mounts / clips for each of my rifles, I can change the lamp easily between rifles, in the past I have tried , a Deben lamp and a Shootalite, IMO ok for rabbits at 50 yds but not much more especially with a red filter fitted, I gave the cluson shootalight to a mate for his air rifle, , I use the 170 for rabbit and fox, if I was just shooting rabbits I would go for the lightforce scope mounted 140,just my two'pence worth.
