Description
Enhanced Clarity and Health: hygger aquarium U-V light adopts a 254nm wavelength designed to help clean green water and algae in aquariums. This U-V light improves water clarity and supports a cleaner aquatic environment for both freshwater and saltwater fish tanks.
4 Timer Modes with Memory Function: Built-in timer offers 3H / 6H / 12H / 24H modes. Once selected, the light automatically manages daily on/off cycles and remembers the last setting after power interruptions.
360° Protective Safety Shield: Equipped with a 360-degree protective shield to help block direct U-V exposure, providing added safety for fish and users during operation.
Two Working Modes for Different Setups: Healthy Mode (Shield Closed): Suitable for direct use inside fish tanks; High Efficiency Mode (Shield Open): Recommended for use inside filter chambers for enhanced algae clean.
Complete Accessories: Includes 1× U-V light with timer, 2× suction cups, and user manual. NOTE: When placed directly in a fish tank with fish swimming, the U-V lamp cover needs to be closed to prevent the leakage of ultraviolet rays.
User Instructions: During the green algae outbreak period, the 24H mode can be used continuously for 3 to 7 days. For daily maintenance, it is recommended to use for 3H per day. Long-term continuous 24H operation will shorten the lifespan of the bulb.
This U-V light is designed to help clean green water, not for instant results. It usually takes 3 to 7 days.
Do not look directly at the U-V light during operation.
For best results, use with proper filtration and regular water changes.
Recommended working time: 3–12 hours per day depending on tank condition.

Common questions about buying open-box and refurbished.
Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $6 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for hygger products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
