Zoo Med ReptiSun 10.0 UVB T8 Fluorescent Lamp, 18 in

High-Penetration UVB T8 Lamp for Larger Terrariums and Screen Covers

The Zoo Med ReptiSun 10.0 UVB T8 Fluorescent Lamp delivers powerful UVB output at a full 20 inches (51 cm) from the lamp surface, compared to 12 inches (30 cm) on the ReptiSun 5.0. At 18 inches, this high-output T8 lamp is optimal for use with larger terrariums where greater than 12 inches of UVB penetration is needed, and is also recommended for use above screen covers which can filter out up to 50% of UVB wavelengths.

With 10% UVB and 30% UVA output, the ReptiSun 10.0 helps prevent or reverse metabolic bone disease in reptiles. High quality construction, made in Germany. Sold individually.

Why Reptile Owners Choose the ReptiSun 10.0

Reptile keepers with larger terrariums or screen-covered enclosures choose the ReptiSun 10.0 for its extended UVB penetration range of up to 20 inches. Where the ReptiSun 5.0 reaches 12 inches, the 10.0 goes further, making it the right choice for taller enclosures or setups where screen covers reduce UVB transmission. The 10% UVB and 30% UVA output, combined with high quality German construction, make the ReptiSun 10.0 a trusted solution for serious reptile keepers.

Quick Product Snapshot

Design and Construction Breakdown

The ReptiSun 10.0 T8 is an 18-inch fluorescent tube lamp engineered to deliver 10% UVB output with a penetration range of up to 20 inches from the lamp surface. This extended range makes it well-suited for larger terrariums where reptiles may bask at greater distances from the lamp, and for enclosures with screen covers that reduce UVB transmission by up to 50%. The 30% UVA output supports natural reptile behaviors including feeding and activity. High quality construction made in Germany ensures reliable, consistent UVB output and long-term performance.

Setup and Compatibility Guidance

The ReptiSun 10.0 T8 is designed for use in standard T8 fluorescent fixtures. It is particularly well-suited for larger terrariums where UVB penetration beyond 12 inches is needed, and for setups where screen covers reduce UVB transmission. Position the lamp so that basking reptiles benefit from the extended 20-inch UVB range. Replace the lamp regularly to maintain effective UVB output, as UVB emission decreases over time even when the lamp still produces visible light.

Care and Maintenance

• Replace the lamp regularly to maintain effective UVB output
• UVB emission decreases over time even when the lamp still produces visible light
• Handle with care to avoid damage to the fluorescent tube

Ideal for Reptile Keepers Who...

• Maintain larger terrariums where UVB penetration beyond 12 inches is required
• Use screen covers that reduce UVB transmission by up to 50%
• Need 10% UVB output for reptiles with higher UVB requirements
• Want a high-penetration UVB lamp with 30% UVA for natural behavior support
• Value high quality German-made construction for reliable long-term performance

Frequently Asked Questions

What is the difference between the ReptiSun 10.0 and the ReptiSun 5.0?
The ReptiSun 10.0 emits UVB up to 20 inches (51 cm) from the lamp surface, compared to 12 inches (30 cm) on the ReptiSun 5.0. The 10.0 also delivers 10% UVB output versus 5% on the 5.0, making it better suited for larger terrariums and screen-covered enclosures.

Why is the ReptiSun 10.0 recommended for screen covers?
Screen covers can filter out up to 50% of UVB wavelengths. The ReptiSun 10.0's higher UVB output helps compensate for this reduction, ensuring reptiles still receive adequate UVB exposure.

What UVB and UVA output does this lamp provide?
The ReptiSun 10.0 provides 10% UVB and 30% UVA output.

Where is this lamp made?
The ReptiSun 10.0 T8 is high quality construction made in Germany.

How often should I replace the lamp?
Replace the lamp regularly to maintain effective UVB output. UVB emission decreases over time even when the lamp still produces visible light.
