Truly sun-like bright naturalistic light for terrariums. Effective UVA and UVB lamps promote calcium deposition and metabolism, strengthen bones, prevent metabolic bone disease, and emit 5000K warm light, avoiding harsh and strong light stimulation. Better performance with higher diameter flux and conversion output. Increased built-in reflector area with an inner reflective coating efficiently enhances luminous flux and heat reflectance inside the lamp, resulting in a brighter environment and higher heat output at the same power level. Professional lamp construction provides 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 basking.
