The lamp emits ultraviolet C radiation aimed at reducing free-floating algae and controlling harmful microorganisms in pond water. Intended for seasonal replacement, this UVC lamp supports clearer water conditions and complements mechanical and biological filtration by improving overall water clarity and reducing the need for manual maintenance.

Advantages

The lamp provides a consistent output of UVC radiation at a power rating of 15 watts, ensuring effective exposure for water passing through a UV clarifier. It is manufactured to fit compatible pond sterilizer housings and offers straightforward replacement without altering existing filtration setups. By targeting single-cell algae and certain pathogens, the UVC lamp assists in maintaining visual clarity and reduces biofouling on other equipment.

Suitable for

• Replacement in compatible pond sterilizers and inline UV clarifiers
• Seasonal maintenance to restore UV effectiveness after prolonged use
• Support of filtration systems to reduce green water and microorganisms
• Use in garden ponds, small ornamental lakes and water features where a 15 W UVC lamp is specified

Key specifications

• UVC power rating: 15 W
• Type: low-pressure UVC germicidal lamp for water treatment
• Intended application: pond water sterilization and algae control
• Form factor: tubular lamp suitable for compatible UV sterilizer housings
• Typical replacement interval: seasonal or after recommended operating hours for maintained effectiveness

How to use

Before replacement, turn off and disconnect the UV sterilizer from the power supply and allow the unit to cool. Remove the protective cover or housing according to the sterilizer manufacturer's instructions, then carefully extract the old lamp without touching the glass with bare hands. Install the new 15 W UVC lamp into the lamp holders, ensuring secure electrical contacts and correct alignment. Reassemble the unit, verify seals and O-rings if present, and restore power. After installation, run the UV unit as part of the regular filtration cycle to achieve continuous exposure of pond water to UVC radiation.

Usage recommendations

Replace the UVC lamp on a seasonal schedule or after the manufacturer's recommended operating hours to maintain optimal sterilization performance. Handle the lamp with clean gloves or a soft cloth to avoid skin oils on the glass, inspect seals when reassembling the unit, and follow local disposal regulations for used fluorescent or mercury-containing lamps.
