Use High-Lux Focused Beams: The 15,000 lux output of GL-ZM ensured visibility over 100 meters ahead, critical in narrow tunnel paths.
Smart Battery Monitoring: Use of digital battery status indicators helped miners track charge without removing helmets.
Multi-Clip Compatibility: Designing for helmet universality saved major time and cost on field adjustments.
Always perform a full-site compatibility assessment before finalizing models.
Local language training and manual translation are vital for adoption in non-English speaking regions.
Moisture resistance is critical in deep underground mines; never compromise on IP ratings.
Invest in durable charging infrastructure to avoid downtime.
Offer spare parts kits — screws, LEDs, cables — to empower self-repair teams.
