Batteries

What is the expected battery life?
About 2 hours continuously

What is the current consumption of the bulb in ProVision circuitry?
Battery life depends on usage and battery type.  It is difficult to define this as different battery made by different manufacturers may last different hours.  For normal usage where the scope is lighted up only when searching for needed things, the scope battery can last couple of months. Scientifically,  PV100 would last about 2 hours (with good and new battery) if it is lighted up continuously till the battery is flat.

PV1 - From fresh good batteries you can easily expect 2 hours continuous current
Current draw starts at about 560mA and keeps on dropping as the batteries are discharged.  After 2 hours the current is down to about 500mA

PV2 - From fresh good batteries (e.g. duracell) you can expect  minimum 40mins current
Current draw is about 560mA.  PV2 has a constant current circuit

For the battery life, why is PV2 taking only 40 min while PV1 takes a longer time to exhaust the battery when both of them use around 560mA to 500mA?
PV2 has a constant current drive circuit while PV1 has two pieces of metal connecting to the light bulb. The electronic circuit (logic) uses some energy and rest is used to step up current as voltage of batteries drop.
