We utilise high-purity quartz glass tubing, achieving a 90% transmittance rate for 253.7 nm ultraviolet light.

- Installation Instructions: The 2G11 uv disinfection lamp requires simple insertion into a compatible 4-pin filter for immediate operation (please verify your fixture specifications match the disinfection bulb prior to purchase).
- Caution: 18W 2G11 UVC light possesses strong DNA penetration capability. Direct exposure to humans, animals, and plants is strictly prohibited when using this product. Never look directly at the light source.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
