LED Caving and Mining Lamps

The main product features of this new, improved LED caving lamp are:

• Quality: Higher-quality lamp housing using top quality materials. New, more positive on-off switch mechanism. Brighter main beam (now 80Lm, previously 50Lm) and pilot beam.
• Performance: Improved brightness compared with earlier specification - now 3000-6000Lux compared with 2500-3000Lux. Focused beam with up to 15 hours running time from full charge, usage life 1200 cycles (reasonable usage).
• Reliability: High strength, lightweight housing, solid-state LED light source with high efficiency current controlled drive circuit.
• Convenience: Unique smart charger design allows the maintenance-free Li-ion battery to be topped up at any time and ensures it cannot be overcharged.
• Safety: The improved ultra bright white LED head lamp is in a fully sealed, anti-static housing with short-circuit protection - making it virtually explosion-proof and ideal for use in mine exploration as well as caving.
• Durability: Glass front lens - doesn't scratch like the plastic lenses on some other caving lamps.
• Environmental: Uses a long-lived rechargeable Li-ion battery - more environmentally friendly than disposable batteries.
• Size and Weight: Compact, lightweight, convenient belt-mounted battery pack measures just 76x31x79mm and fits onto a standard 40mm wide belt. The whole unit weighs just 600g.

User guide

1. No need for initial charging regime or "cycling" of the high power Li-ion battery - the lamp can be used immediately. (Charge fully before going caving though!)
2. Smart-charger uses constant-current up to ~70% charge (charge indicator LED is red), then switches to constant voltage charging until lamp is fully charged (charge indicator LED is green). The charger then powers-off. This prevents over charging and allows the battery to be topped up at any time.

Daily maintenance

1. In case of short-circuit, the protection circuit will cut off the power in an instant. After the short-circuit problem is resolved, re-switching on of the lamp restores functionality.
2. This LED caving lamp should not be used or stored at temperatures over 60ºC. Store in a cool, dry place. For long-term storage charge the battery to approx. 50% charge twice a year.
