Using the Exo Terra Infrared Basking Spot Lamp is easy. First, choose the right wattage according to the size of your terrarium. Then, install the lamp in a suitable fixture, making sure it's securely placed. You can adjust the direction of the heat using the built - in reflector. This lamp can be used 24 hours a day as it won't disrupt the normal activity of your terrarium animals. When using it in combination with Repti Glo or Sun Glo, set up a proper cycle to meet the needs of your pets. For maintenance, turn off the lamp and let it cool down completely before cleaning. Use a soft, dry cloth to wipe the bulb gently. Avoid using any harsh chemicals or abrasive materials. If the lamp stops working or shows any signs of damage, replace it immediately to ensure the safety and well - being of your terrarium inhabitants.
