This Bottlelight is used to illuminate empty wine bottles, champagne bottles, or other bottles with a bottle neck diameter of 17-20 mm. The light emits a pleasant, non-dazzling light. The bottle light is powered by two standard AA alkaline batteries (1.5V) or two rechargeable NiMH cells (1.2V), which can be easily filled or replaced when the lid is open. The first brightness (15lm) is switched on/off by simply twisting the lid up to the battery contact. The second brightness (50lm) is activated by briefly switching off and on again by turning the lid accordingly. After switching off for a longer period (>1s), the first brightness is activated again. In this way, brightness can be easily adapted to requirements. An electronic system keeps the respective brightness constant. The bottle light is waterproof from the bottom to the lid and rainproof from the top. For safety reasons, the light must not be placed in drinks. The light must be kept away from children under the age of three.
