The Zilla Night Black Incandescent Spot Heat Bulb is a great way to add some extra warmth to your home. These bulbs provide more focused ambient heat without disrupting your sleep or visuals, making them perfect for use in bedrooms, living rooms, offices, or any other room in your house. With a gentle glow, these bulbs are also great for viewing nocturnal habits and shy species activities. The heavy-duty filaments yield hours of performance, while the pinpointed light and heat allow reptiles to easily move away from the heat source and regulate their body temperatures.
