Hi all! We are new owners to a two-year-old Russian tortoise named Shellma that we adore. Time to get a ceramic heat lamp for at night and a back up battery charger. Can someone make recommendations on brand and a link if possible? I have no idea what to look for. Can the ceramic Bulb be used interchangeably with her daytime lamp? We have the zoommed dual lamp. Also I say most of the battery chargers are for under 100 W the lightbulbs in the lamps are 150. So confused! Also need a timer for the lamp.
