This high-efficiency bulb has an 8,000-hour life, so it should be replaced after 11 months of continuous operation. Make sure to replace every pond season – the bulb may continue to glow, but its effectiveness in killing algae diminishes. Convenient viewing window in TetraPond GreenFree UV Clarifier makes it easy to ensure the bulb is working. Replacement bulbs are available in four sizes: 5 watts for ponds up to 660 gallons; 9 watts for up to 1,800 gallons; 18 watts for up to 4,400 gallons; and 36 watts for up to 8,800 gallons. TetraPond GreenFree UV Clarifier (not included) works to keep your pond clean, clear, and free of unsightly green algae. These dependable clarifiers use ultraviolet light to destroy suspended green algae. As algae are pumped into the clarifier, they are exposed to ultraviolet light that destroys the reproductive ability of single-celled algae. The dead algae are then pumped out of the TetraPond GreenFree UV Clarifier, where they clump and are removed by your pond's filtration system. Removes heavy algae blooms (usually within 8 days) and keeps the pond algae-free long-term. Since 1951, Tetra has developed the world’s most comprehensive body of fish food knowledge, and fishkeeping enthusiasts have looked to the brand for products and solutions that add ease and beauty to their home. Whether you're an experienced hobbyist or just starting out, Tetra has everything you need – from a large variety of quality fish food and innovative equipment to test kits and decor. ## Features - REPLACEMENT BULB: For use in TetraPond GreenFree UV Clarifier to control heavy algae blooms in ponds and water gardens and keep water clean and green-free - ULTRAVIOLET LIGHT: Destroys the reproductive ability of single-celled algae - ANNUAL MAINTENANCE: Replace bulb every pond season for continued algae control - HIGH-EFFICIENCY: For up to 11 months of continuous operation - 4 AVAILABLE SIZES: 5 watts for ponds up to 660 gallons; 9 watts for up to 1,800 gallons; 18 watts for up to 4,400 gallons; and 36 watts for up to 8,800 gallons ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00474FIBG | | Accepted Voltage Frequency | 100 to 120 Volts and 60 Hertz | | Additional Features | Long Lasting | | Brand | Tetra | | Brand Name | Tetra | | Bulb Base | Wedge | | Bulb Shape Size | F10 | | Color Rendering Index | 80 | | Colour | Green | | Connectivity Technology | Normal bulb | | Control Method | App | | Controller Type | Push Button | | Customer Reviews | 4.6 out of 5 stars 1,252 Reviews | | Efficiency | 9 watts with algae control effectiveness within 5 days and up to 11 months | | Global Trade Identification Number | 00046798195276 | | Incandescent Equivalent Wattage | 40 Watts | | Indoor Outdoor Usage | Indoor | | Is Electric | Yes | | Item Dimensions W x H | 25W x 171H Millimeters | | Item Type Name | Replacement Bulb | | Item Weight | 0.1 Pounds | | Light Color | Green, clear | | Light Output Maximum | 100 Lumens | | Light Source Operating Life | 8000 Hours | | Light Source Type | UV | | Light Source Wattage | 9 Watts | | Light Type | Fluorescent | | Lumens | 100 Lumen | | Manufacturer | TetraPond | | Manufacturer Part Number | 19527 | | Material Type | Plastic | | Model Name | Tetra | | Model Number | 19527 | | Number of Items | 1 | | Package Quantity | 1 | | Power Consumption | 9 Watts | | Power Source Type | Corded Electric | | Shape | Tubular(T) | | Smart Home Compatibility | Not Smart Home Compatible | | Special Feature | Long Lasting | | Specific Uses For Product | Pond Algae Control | | Style Name | Country | | UPC | 046798195276 | | Unit Count | 1.0 Count | | Voltage | 120 Volts | | Wattage | 9 Watts | | White Brightness | 100 Lumens | ## Product Details - **Brand:** Tetra - **Light Type:** Fluorescent - **Special Feature:** Long Lasting - **Wattage:** 9 Watts - **Incandescent Equivalent Wattage:** 4E+1 Watts - **Specific Uses For Product:** Pond Algae Control - **Light Colour:** clear, Green - **Voltage:** 120 Volts - **Net Quantity:** 1.0 count - **Number of Items:** 1 ## Images ![TetraPond UV Bulb for UV1 and UVC, 9-Watt - Image 1](https://m.media-amazon.com/images/I/617cj4N26nL.jpg) ![TetraPond UV Bulb for UV1 and UVC, 9-Watt - Image 2](https://m.media-amazon.com/images/I/51QuPJuJ5EL.jpg) ![TetraPond UV Bulb for UV1 and UVC, 9-Watt - Image 3](https://m.media-amazon.com/images/I/21O7AR+jXQL.jpg) ## Questions & Answers **Q: Who manufacturers the bulb? Philips? Osram?** A: Philips is the manufacturer of our bulbs. **Q: I currently have the tetrapond clear choice biofilter pf-1. can i add this in between the tetra 550 pump & the filter?** A: Yes, you sure can. It goes outside the pond, so you'd put it a few feet from the inlet of the filter. **Q: Is 9W bulb longer that 5W in length?** A: The bulbs come in four sizes,viz 5W, 9W, 18W and 36W. I am pretty sure that the 9W will be bigger/longer than the 5W. **Q: Need a philips tp16787 tetra 9watt replacrment lamp for the puv-1 is it still available** A: i just listed 4 ---tetra 16787 --there not cheap and i only have 4 left ... ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by P***Y on 21 April 2025* ### ⭐⭐⭐⭐ Review *by M***L on 8 January 2020* ### ⭐⭐⭐⭐⭐ Review *by F***K on 18 August 2025* ## Frequently Bought Together - TetraPond Replacement Bulb For GreenFree UV Clarifier, For Clean And Clear Ponds, 9-Watt, 1 Count (Pack of 1) - Summit Clear-Water Barley Straw Pond Treatment, 2-Pack, Treats upto 2000 Gallons, 1000 Gallons per Bale - API POND ALGAEFIX Algae Control 32-Ounce Bottle, FISHAQUARI (169G) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/256776546-tetrapond-uv-bulb-for-uv1-and-uvc-9-watt](https://www.desertcart.hr/products/256776546-tetrapond-uv-bulb-for-uv1-and-uvc-9-watt) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-19*
