Using these Zilla Day Blue Incandescent Bulbs is easy. Just screw them into a compatible socket, like the Zilla® Reflector Domes. They're great for creating a natural daylight environment for your pets, especially reptiles. When it comes to safety, always make sure the bulb is cool before handling it. Avoid touching the bulb with bare hands as the oils from your skin can cause it to overheat. For maintenance, check the bulb regularly for any signs of damage. If you notice that the light is dimming or the bulb has stopped working, it's time to replace it. These bulbs are designed to last, but proper care will help them serve you for a long time.
