Yes, the battery within this light will need to be charged on a daily basis from the solar panel. With a full recharge the light will operate in a dusk to dawn fashion. Thank you for your inquiry!
Do you have a 3 inch version of this? Thanks, Ann
This does not come in a 3" version. However, a magnetic base model is available. That product link can be found below:
