Germicidal lamps are clear with special UV transmitting glass. For use in sterilizers and air and water purifiers. This is an ultraviolet C (253.7 nm wavelength) bulb for use in sterilization, water and air purification and surface disinfection. Used in the Forming and Disinfection of Contact Lenses. Used in UV Sterilizers for Fish Aquariums and Ponds. Fixed wavelength spectrophotometer detector. Germicidal lamps allow 253.7nm UV-C radiation from the mercury discharge to pass through the glass thus penetrating and inactivating the DNA of most micro-organisms.

Warning: Avoid direct exposure of eyes and skin under germicidal lamps. To prevent possible serious injury, eyes and skin should not be exposed to direct or reflected ultraviolet power emitted by this lamp. This lamp is in Risk Group 3 per ANSI/IESNA RP-27.3-96. Adequate protection should be provided by clothing, gloves, opaque materials, and ordinary window glass. Although this lamp will operate in standard fluorescent fixtures, it should not be used for general lighting applications.

Go to our Germicidal Safety Sheet for more lamp handling details.

Note: This lamp contains Mercury. Manage in accord with disposal laws. See



Special Note: We had a customer with a Taiji HC-12UVC Hot Cabi that said the moisture seal did not fit properly on the GTL-2 lamps we are selling. They said the diameter of our lamps is too small. I measured a sample lamp and the sample lamp measured 16.98mm or .6685" in diameter. This means the difference is approximately 3mm so something 1.5mm thick as a spacer might resolve the problem.
