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, "push button" on-off switch mechanism - almost impossible to switch on accidentally. For 2008 model, an even brighter main beam (now 90Lm, previously 80Lm) and pilot beam.
• Performance: Improved brightness compared with earlier specification - 2008 version now 10,000 Lux compared with the 2007 model at 6,000Lux. 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. Sealed impact-, water- and temperature-resistant battery.
• Environmental: Uses a long-lived rechargeable Li-ion battery - more environmentally friendly than disposable batteries.
• Size and Weight: Compact, lightweight, convenient belt-mountable battery pack measures just 78x31x79mm and will fit onto a standard 40mm wide belt or into an oversuit pocket. 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 60°C. Store in a cool, dry place. For long-term storage charge the battery to approx. 50% charge twice a year.
