FAQ Technical details

What precautions should be taken when charging with charger 115/230V(first model) ?

1. Check the condition of the lamp’s charging pins: very dry.
2. Check that the charger’s K7 plug is plugged in with the white mark on the side aligned with the white spot.
3. Check that the rapid charger’s mains current switch is properly positioned (115 or 230V).
4. Plug the charger into the lamp then into the mains (white mark aligned with the white spot).
5. Check that the red LED is lit to indicate rapid charging. It should then automatically switch to trickle charging (green LED) with no time limit.
If the charger does not switch during rapid charging:
- check the position of the lamp’s on-off switch and that the cam is in place,
- check the lamp is working properly,
- check the condition of the connectors,
- unplug the charger, wait for the LEDs to fade completely then plug the charger into the lamp before plugging it into the mains.

How long should a lamp be plugged into the charger?

- For a standard charger: the charge time varies from 10 to 14 hours according to the products.
The charge does not stop automatically. The LED lights up to indicate charging. If you charge it for longer, there is no serious effect provided that this is not repeated too often. A safety switch automatically cuts the current if the temperature of the cells exceeds the set point.

- For the rapid charger: the electronic charger conducts an accelerated charge at a constant current then automatically switches to trickle charging once the cells are charged (without endangering the cells in any way over a long period). The cells are charged from a 230V 50Hz or 115V 60Hz power source (voltage selector on the charger). Consumption of the charger: 25 VA maximum. The lamp can be charged regardless of the charge level of the cell pack.
