Oldham Caplamp GL9 – Hazardous Area Group 1 Mining M2 ATEX Lamps

ATEX Certified ◊ Group 1 Mining ◊ Hazardous Areas

Oldham Caplamps are Hazardous Area Group 1 Mining Caplamps for safe use in underground hazardous location mines and non-hazardous (hard-rock) type mines.

Oldham Caplamp GL9 combines reliability and rugged construction with the latest industry standard Halogen bulb G-Series lamp headpiece with the smaller and lighter lithium-ion (li-ion) L9 battery pack.

The Oldham GL9 is not certified against mining safety standards and is therefore only recommended for use in hard-rock mining and tunnelling or other non-hazardous mining applications.

Please note the Oldham GT5 is now obsolete and the Oldham GL9 is a direct replacement

Oldham Caplamp GL9 ATEX Lamps – Features & Benefits

• Extreme lightweight of the Lithium-ion battery – reduced weight for user to carry, less fatigue.
• Lithium-ion battery does not suffer from “memory effect” – full capacity available every time after recharge.
• Lithium-ion battery has low self-discharge rate – long caplamp shelf life if stored during mine down-time.
• Rugged battery and headpiece design – longer life expectancy, even in the harshest environments.
• Fully repairable “G” headpiece: Low operational and life running costs.
• 38 lumen output focussed over 3.0 degrees angle: High intensity light concentrated in the operator’s field of vision.
• Bulb manufactured to Oldham’s specific criteria: Optimised lighting and battery performance even at end of shift
• Inter-modular battery and lamptop design – fully compatible & interchangeable with other Oldham products.
• Mixed charging versatility – although micro-processor type chargers always give the best performance, the L9 battery is fully suited to recharge on conventional constant-current chargers
