cree upgrade bulbs
I Put new cree 1 watt upgrade bulbs into two old Petzle Zoom headlights, put one on spot/main beam,and the other on general, Left them both on without a break, since yesterday to test battery life, using normal AA batteries, two sets of three, in the adapter. They have been on for 24hrs solid/none stop, and are still as bright as when I switched them on yesterday.they are brill, and have fantastic battery life.
