Truly sun-like bright natural light for terrariums. Effective UVA and UVB lamps promote calcium deposition and metabolism, strengthen bones, prevent deficiencies, and emit 5000K warm light while reducing harsh light stimulation. Superior performance with increased diameter flux and conversion output. Built-in reflector with inner reflective coating efficiently enhances luminous flux and heat reflectance inside the lamp, creating a brighter environment and higher heat output at the same power level. Professional lamp construction delivers a true flood-lamp effect and eliminates dangerous UV "hot-spots" commonly found in other metal halide reptile lamps. Suitable for most reptiles, lizards, snakes, spiders, and other animals that require heat and UV exposure for healthy living. Color: White. Material: Quartz glass. Size: 12 x 8 cm. Package Contents: 4 x Heating bulb. Note: Light reflection and different displays may cause slight color variations between the image and the actual item. Measurement error allowance is +/- 1-3 cm.
