Reptile UVB Bulb Hagen Exo Terra Repti UVB200 25W – compact fluorescent UVB lamp for reptiles

The Hagen Exo Terra Repti UVB200 25W compact fluorescent UVB lamp is designed to deliver controlled UVB radiation for reptile terrariums that require supplemental ultraviolet exposure. This lamp supports natural vitamin D3 synthesis and calcium metabolism in reptiles when installed in appropriate fixtures and reflectors. The compact size makes it suitable for smaller enclosures or secondary placement where standard linear tubes are impractical.

Advantages

The compact fluorescent design provides consistent shortwave UVB output throughout its recommended service life while generating relatively low heat compared to incandescent alternatives. Its shape and size allow flexible placement inside or above terrarium fixtures with reflectors, improving light distribution. The lamp is intended to reduce the risk of metabolic bone disease by promoting vitamin D3 production under supervised conditions and helps maintain diurnal activity patterns in species that require UVB exposure.

Suitable for

• Small to medium-sized terrariums where full-length tubes are not an option
• Reptile species that require supplemental UVB (e.g., many lizards and diurnal snakes)
• Situations requiring a compact lamp for secondary or localized UVB coverage

Key specifications

• Type: Compact fluorescent UVB lamp
• Power: 25 W
• Radiation: UVB output suitable for vitamin D3 synthesis support
• Form factor: Compact lamp designed for use with appropriate fixtures and reflectors
• Heat output: Low to moderate compared with incandescent UV sources

How to use

Install the lamp in a fixture compatible with compact fluorescent bulbs and include a reflective backing or reflector to maximize usable UVB within the enclosure. Position the lamp at a distance recommended for the specific reptile species and enclosure size to provide effective but safe UVB exposure. Replace the lamp according to the manufacturer's suggested interval or when measurable UVB output declines; lamps can continue to emit visible light after UVB output has decreased. Do not allow direct contact between the bulb and animals or moisture; ensure electrical fittings are dry and properly secured.

Usage recommendations

Use in combination with regular temperature gradients, appropriate hide spots, and a balanced diet including dietary calcium. Measure UVB levels with a suitable UV meter where precise dosing is needed, and consult species-specific husbandry guidelines to determine daily exposure times and mounting distance.
