Fluker's Sun Spot Bulb is a versatile, powerful bulb that operates as a powerful heat source as well as producing essential UVA and UVB wavelengths for reptiles such as bearded dragons, iguanas, chameleons, water dragons, aquatic turtles and many more. UVB radiation is essential for captive reptiles as it helps to stimulate the production of vitamin D, while also helping to reduce the chances of contracting metabolic bone disease. UVA radiation on the other hand, encourages appetite, vibrant coloration and breeding activity. The bulb boasts a special UV transmitting hard glass and has a 5000 hour lifespan. Produces 160 watts of power.
