well i think both of those lights are way to much but if thats all ya have then use the weeker one with the red lens.the red lens will cut the candle power down some and if you learn to use just the edge or outer rim of light on the critters they won't turn away.so you can see just how bright those realy are,have a buddy hold the light and you get around 100 yards away.have him hit your eyes with the center of the beam,you will find that it hurts to look at.those big candle power lights work good for shooting already treed coon but will spook coyote,even with the red lens on.use the very edge of the beam and it just might work out for ya.
