Jeff, I am totally convinced that there is "NO" sight brighter than the Viper Pro Predator sight, no light need for these. Makes for a good hunting and 3D sight. Check out their website http://www.viperarcheryproducts.com
and then go to the 3dshoots.com store and buy it. You won't find them cheaper anywhere else.
When your done with all that,check us out at Missouriwhitetails.com
