Using the Reptile Systems New Dawn 6500K LED Bulb is easy. Simply install it in your terrarium or vivarium. Make sure it's securely in place. When using, keep in mind that although it's safe for high - humidity enclosures, avoid direct splashing of water on the bulb. For maintenance, turn off the power before cleaning. You can use a soft, dry cloth to wipe away dust every few weeks. This will help keep the light output strong and ensure the long - term health of your plants.
