Spot Hogg sights are very good IMHO, but there are other manufacturers that are excellent also. Why do you ask?
I don't use the lights because if I can't see pin it's to dark. But some people with eye sight not as good as mine may use it. It's all just personal opinions.
Trophy ridge react 5 pin sight, those pins light up good I have even shot when its dark and dead on at 20,30 yrds.....
I forgot to mention that even if you don't have the light on the pins on tr react are nice and bright.
I like CBE lights on their sights. Only the tip of the pin is lit when the light is turned on. Also, lights are great for a sight especially when hunting from a Groundblind.
Black Gold sights are the brightest pins ive ever used and they have a bomb proof lifetime warrenty no questions asked. I have bought a new one every time I get a new bow, you can also custom order your sight for different colors and pin sizes.
Trophy Ridge sights have very bright pins, and most of them also come with rheostat lights for ground blind hunting. The pins are bright enough on their own you'll likely never need the light up in a tree or out in the open. I prefer the React Pro, but I've also had the react 5, react 1, and the micro Hitman 5 and they all have the same bright pins.
