Thank you for contacting us regarding the product.
This product does not have a memory chip, so it remembers the selected colour as long as the battery has charge. Once the battery gets completely discharged, the settings reset and start from the default.
What we may suggest is to select the timer (via the remote control) so it helps to preserve the battery charge. The way the timer works is: the light will automatically turn on at dusk, stay for the selected number of hours and turn off (otherwise, it would stay on till dawn or until the battery got discharged). The next day, the cycle will repeat.
Some models (usually more advanced) have a memory chip.
Should you have any questions or require further assistance, please do not hesitate to contact us.
Warm Sunny Regards,
