Wisdom 4A: the 3A Plus with power-bank capability

The Wisdom 4A has the same brightness levels, beam distances, runtimes and 7,000 mAh battery capacity as the 3A Plus.

The power-bank function is the only practical difference between the Wisdom 3A Plus and Wisdom 4A. The 4A can provide emergency power to a compatible USB device, which may be helpful during remote work, outdoor trips or power disruptions.

• High: 533 lumens, 316-metre beam and up to 5 hours runtime
• Medium: 265 lumens, 219-metre beam and up to 13 hours runtime
• Low: 50 lumens, 85-metre beam and up to 60 hours runtime
• 7,000 mAh rechargeable battery
• USB power-bank function
• IP68 water-resistance rating
• Approximately five-hour charge time

If device charging is useful, choose the 4A. If you only need the lamp and identical lighting performance, choose the 3A Plus.

Wisdom 6A: certified for hazardous mining environments

The Wisdom 6A is the model intended for buyers who require the listed hazardous-area certifications.

• IECEx, ATEX M1 and ANZEx certified
• High output up to 240 lumens
• Low output up to 50 lumens
• Beam distance up to 220 metres on high
• Up to 13 hours runtime on high
• Up to 60 hours runtime on low
• IP68 waterproof housing
• Dive-rated to 20 metres
• Desktop charger included

Certification is model-specific. The 3A, 3A Plus and 4A should not be treated as substitutes where the 6A’s IECEx, ATEX M1 or ANZEx certification is required. Always compare the exact equipment marking and certificate with the site’s hazardous-area classification and workplace approval requirements.
