LSE Lighting 14W UV-C Replacement Lamp for Aquascape UltraKlean 1000/2000 — 9-inch 4-pin, 254 nm

The LSE Lighting 14W 9-inch 4-pin UV-C lamp is a direct replacement bulb engineered to restore UV performance in Aquascape UltraKlean 1000 and 2000 biological pressure filters.

This lamp is built to match the original equipment specifications for Aquascape UltraKlean 1000 and 2000 systems, offering a precise fit, high UV output, and dependable lifespan. Designed with a 4-pin base (all pins on one end) and a 9-inch quartz glass envelope, it produces strong 254 nm ultraviolet light at 14 watts to maintain the UV function of your pond or water feature filtration. Manufactured in an EPA-registered facility and backed by a one-year warranty, it gives a straightforward maintenance option for hobbyists and professionals who need consistent replacement parts.

Will this bulb fit my Aquascape UltraKlean 1000 or 2000?

Yes — the lamp is engineered as a 100% compatible replacement with the same pin configuration and physical dimensions as the original factory bulb. You can swap it in without adapters or housing changes, ensuring the unit seals and electrical connections function correctly.

• 9-inch (212 mm) quartz glass tube length for exact fit
• 4-pin base with all pins on one end matching OEM pinout
• No housing modification required for Aquascape UltraKlean 1000/2000

How much UV output and what wavelength does this lamp deliver?

The lamp outputs 14 watts of high-output UV-C energy focused around 254 nm, the wavelength commonly used for disinfecting and reducing free-floating organisms in recirculating water systems. That level of output is specified to restore the UV function in compatible UltraKlean models when replacing an aged or failed bulb.

• 14 W high-output rated power for reliable performance
• Peak emission near 254 nm for effective UV-C activity
• Quartz glass envelope to maximize UV transmission

How long will this replacement lamp last and how often should I change it?

The lamp is designed for practical service life under normal operating conditions and LSE recommends replacing it every 12 months for consistent UV performance. While the bulb may visibly light beyond that interval, UV output degrades over time so annual replacement keeps the system working as intended.

• Suggested replacement interval: 12 months for optimal UV output
• Backed by a 1-year manufacturer warranty for peace of mind
• Durable quartz construction resists thermal stress in typical filter housings

Is this lamp safe and made to quality standards?

This UV-C lamp is produced in an EPA-registered establishment and follows recognized manufacturing controls to ensure consistent quality. As with any UV-C source, handle carefully: avoid direct skin and eye exposure and follow the filter manufacturer’s safety and installation instructions.

• Manufactured in EPA Registered Establishment No. 96823-PA-1
• Quality checks for pin alignment, glass integrity, and output consistency
• Follow Aquascape and LSE safety guidance during installation

Who is this for: Pond owners, landscapers, and water-feature technicians who operate Aquascape UltraKlean 1000 or 2000 biological pressure filtration systems and need an exact, reliable UV-C replacement bulb. It’s aimed at users who prefer an OEM-style fit, measurable UV output around 254 nm, and annual maintenance cycles to keep water clarity equipment functioning as specified.
