I have an old blt helmet light with a 15 watt halogen bulb replacing the original 10 watt. I just picked up a 6 volt 8.5 amp/hr lead acid battery to replace my old 7 amp/hr. Is there a way to calculate the approximate burn time?
This setup is an interim measure until I buy a new light, probaly one of the new led's that are conming out.
