Oldham Caplamp DL9 – 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 DL9 combines reliability and rugged construction with the latest LED and lithium-ion (li-ion) technologies to produce a brighter, longer lasting and smaller/lighter lamp.
The Oldham DL9 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.
Oldham Caplamp DL9 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.
- Maintenance-free battery design – reduced lamp room maintenance requirements.
- Maintenance-free “D” headpiece – no downtime due to maintenance or failed light source.
- 53 lumen output focussed over 4.5 degrees angle – high intensity light concentrated in the field of vision.
- Dual reflector technology – optimum focus of LED for precise and intense illumination.
- Genuine 3 Watt LED main light source – greater light output intensity, superior to any competitor.
- 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
