About This Spiral surface design: Longer filament increases the filament resistance, expands the heating area, and increases the filament temperature in short time. Nickel-chromium alloy resistance wire increases heating speed and area, reduces energy consumptions. No light emitted: Bulb emits natural heat without any visually detectable light that can disturb the sleep cycle of your pets. Up to 99% thermal efficiency by adopting material into ceramic raw materials. Perfect 24 hours heat sources: Great for reptile and amphibian terrariums, incubating poultry heater. The high-strength ceramic shell makes the heat concentrated more on the surface of the ceramic disc. Specification: Voltage: AC 120V; Power: 60W; Main material: ceramic; The ceramic heat emitter for use in standard E26 lamp base and easy to install, rated for up to 30, 000 hours. Heat Lamp Diameter 76mm, length 110mm. Note: High surface temperature, please keep an appropriate distance from flammable materials and pets, so as not to cause serious consequences. To avoid scald, please wait at least 1 hour to cool down after turning off the bulb.
