I I have a boss belt light with the cats eye head, it's the brightest light I have ever had, plus it has the built in red led for summertime hunting. Most any of the 21-28 volt led belt lights are gonna give you great brightness.
i have a 21 volt k-light with the led g2 head. its a belt light im pretty sure my next one will be a bump cap light, that way i aint got the cord to get hung on vines. been wanting the bump cap forever just cant wear this k-light out.
