The UVB 2% bulb is perfect for simulating natural sunlight. The compact lamps are ideal for small terrariums with a maximum length of 600 mm. These lamps can be installed in standard screw lamp sockets without the need for an external ballast. They are also energy-efficient, generate very little heat, and consume less energy than UVB tubes. This bulb is perfect for reptiles that do not require high UVB levels. It has a strong production of UVA rays, which promote vision, appetite, and the immune system. UVB, on the other hand, enables the production of vitamin D3. The light emitted by this bulb is cool, white, and bright, allowing for excellent color rendering.
