The tried and tested Chala 12-HD lamp has been modernised: White LED's replace the bulbs. It features six white LED's and a red charge control lamp. Battery cycle is five hours.
Now: Microcontroller with controlled charging electronics!
Apart from these new features, the CHALA lamp is still the same.
When plugged into a motorcycle's 12 V electrical system, it can be used as a camplight. Use it as a rechargeable torch or for charging the four batteries.
