【Temperature-Controlled Heat Lamp】 The heat lamp with four-stage temperature control allows you to easily set the desired temperature. 【Cycle Timer】 This reptile heat lamp is equipped with a smart timer that offers three time options (2H, 4H, 8H). Press and hold the corresponding timer button until the LED indicator flashes to activate the 24-hour cycle function. This function ensures that the lamp automatically turns on and off at the same time every day, thus meeting the lighting needs of different pets. 【UVA and UVB Reptile Lamp】 This turtle heat lamp mimics the sun's UVA light to promote bone growth in reptiles. At the same time, the UVB light from this lamp accelerates vitamin production, allows for optimal calcium absorption, and prevents diseases caused by insufficient light. Therefore, it is an indispensable accessory for your pets at home. 【High-Quality Materials】 The HeatingLux tortoise lamp consists of an extremely robust clamp and a 360° flexible tube, allowing you to adjust the lighting angle to your liking. Moisture-resistant and non-slip, it easily attaches to all types of terrariums. Two 75W bulbs are also included.
