WP night vision simply has better battery life than thermal.
This video highlights a significant advantage of white phosphor night vision over thermal imaging: battery life. While thermal technology has improved, it continues to consume batteries considerably faster, especially in cold conditions. White phosphor night vision, exemplified by a PVS-14, can achieve up to 50 hours of continuous operation on a single AA battery, a stark contrast to the rapid depletion often experienced with thermal devices.
