Wisdom Cordless 4A Cap Lamp - Super-bright Cap Lamp / Headtorch - Three Brightness Levels

Retail Pack

The Cordless 4A is Wisdom's latest generation cordless lamp. It is a very popular lamp for all manner of outdoor activities; from caving and mine exploration to hiking, walking, mountain biking, fishing and camping; anywhere where a lightweight, bright, tough and rechargeable light is needed.

The retail pack version includes the following accessories:

• A comfortable elasticated head strap
• A lanyard for securing the lamp
• Bracket for attaching to handlebar of bike / mountain bike
• Red filter, lens #1 (diffuses the light) and lens #6 (focuses the light) - variously useful for cycling, night vision or when camping etc.
• Magnetic USB charging lead
• USB Power Pack with UK plug for faster charging

The same quality of construction goes into the Wisdom Cordless lamps as the KL series, and unlike many similar lamps the 4A features a tough glass screen that is not prone to scratches as cheaper plastic-fronted lamps are.

The Cordless 4A offers three brightness levels as follows:

• High power: 25,000 Lux / 533 lumens - 316m beam - 5 hour run time
• Medium power: 12,000 Lux / 265 lumens - 219m beam - 13 hour run time
• Low power: 1,800 Lux / 50 lumens - 85m beam - 60 hour run time

An additional benefit of the Cordless 4A lamp is that the integral 6.2Ah LiIon battery can be used as a power bank, for example to charge a mobile phone whilst away from mains power.

The Cordless 4A lamp uses a genuine Cree LED and genuine Panasonic LiIon rechargeable batteries. It provides both an excellent beam - capable of illuminating objects up to 316m distant - and a good spread of light allowing you to see foreground and distance. The lamp weighs just 169g and is IP68 rated - totally dust tight, protected against prolonged effects of immersion under pressure.

All Wisdom Cordless series lamps supplied by are pre-fitted with the robust hinging metal clip / bracket - allowing the angle of the lamp to be rotated by 47°.
