Frequently asked questions

Have questions? We’re here to help

Title

Q1: How does the thermal management system prevent overheating?

A: Our UltraFire™ technology combines 6061-T6 aluminum housing, diamond-patterned heat sinks, and dynamic current regulation. When internal sensors detect temperatures exceeding 65°C (149°F), the system automatically reduces output by 15% while maintaining safe illumination levels.

Q2: How do I maintain the switch mechanism?

A: Clean monthly with electrical contact cleaner. The gold-plated switch contacts resist corrosion – no lubrication needed. Avoid silicone sprays near the button.

Q3: What maintenance ensures longevity?

A: Perform quarterly O-ring lubrication with included silicone grease (NSF H1 certified). Avoid using petroleum-based lubricants which degrade the 7075 aluminum threads.
