This is our new LED 6 head. It is our brightest head producing 1200 lumens. This head will work on any 21 to 28 volt battery pack but is optimal with 24-28. However, if you have a battery pack designed for a convential head we recommend you let us change the switch or you will not be able to dim it like you want.
