Exo Terra Reptile UVB100 Compact Lamp

The Exo Terra Reptile UVB 100 Compact Lamp is designed for tropical and sub-tropical reptile keepers who need reliable UVB output in a compact fluorescent format. Replacing the former Repti Glo 5.0 with an improved spectrum, this lamp delivers the moderate UVB levels that mirror shaded rainforest and tropical environments — where humidity, weather variation, and canopy cover naturally filter direct sunlight before it reaches the animal.

UVB Output and Vitamin D3 Synthesis

Reptiles kept in tropical setups depend on consistent UVB exposure to photosynthesise vitamin D3, which in turn drives calcium absorption and supports long-term skeletal health. Without adequate UVB, the risk of metabolic bone disease increases significantly. The UVB 100 is calibrated to provide an optimal D3 yield index suited to species that would naturally experience moderate rather than intense UV exposure in the wild.

UVA and Behavioural Benefits

Alongside UVB, this lamp emits UVA radiation, which plays a direct role in stimulating natural behaviours in captive reptiles. Appetite, activity levels, and reproductive behaviour are all positively influenced by appropriate UVA exposure — contributing to the overall wellbeing of the animal beyond basic physiological needs.

Effective Range and Placement

The UVB 100 is effective up to 40 cm from the lamp, making placement and basking zone planning straightforward. It is available in two output options to suit enclosures of different scale — choose the appropriate wattage from the variant selector above based on your setup size and the distance between the lamp and your reptile's basking position.

Compatibility and Light Spectrum

• New improved spectrum — successor to the Repti Glo 5.0
• Suited to all tropical and sub-tropical reptile species
• Effective UVB range up to 40 cm
• UVA output supports appetite, activity, and reproductive behaviour
• Can be combined with a Natural Light or Reptile Vision lamp to broaden the visible light spectrum in the vivarium
• Compact design fits standard E27 lamp holders used in Exo Terra terrariums and compatible fixtures

For keepers running tropical or rainforest-style terrariums, the Exo Terra Reptile UVB 100 Compact Lamp provides a well-matched UVB profile without the intensity of desert-rated bulbs. Select the wattage that best fits your enclosure dimensions and lamp positioning to ensure your animals receive consistent, appropriate UV exposure.
