LED aquarium submersible lamp for fish tank lighting with 5050 SMD chips in blue or white

This LED aquarium submersible lamp is a practical underwater lighting solution for fish tanks, aquariums, cisterns, rockeries, and pet cages. Designed to be fully sealed for safe use below the waterline, it helps you see your fish and reptiles clearly as they swim or move. The lamp uses energy-efficient 5050 SMD LEDs that add colour and contrast to your aquatic setup without generating excessive heat. Available in two light tones—blue for a natural ocean feel or white for bright daytime visibility—it fits a range of tank sizes and aesthetics.
Features and Construction

The lamp is built for straightforward underwater installation and reliable long-term use. Its fully sealed construction keeps water out, while the two included strong suction pads make attachment quick and secure on clean glass or smooth surfaces.
Material and Build
Constructed with a waterproof sealed housing and 5050 SMD LED chips, the lamp is designed for submersion in fresh water. The power cable measures approximately 135cm plus an additional 45cm, giving flexibility for placement near tank power outlets. The lamp runs on AC100-240V/DC12V via the included transformer, ensuring safe low-voltage operation.
Size and Practical Fit
The lamp comes in four overall lengths: 18cm, 28cm, 38cm, and 48cm. Each length corresponds to a specific number of LEDs and power consumption: 9 LEDs at 2W, 15 LEDs at 3.8W, 21 LEDs at 4.8W, or 27 LEDs at 5.8W. Choose the size that best matches your tank’s width or coverage area.
Uses and Placement

This versatile lamp is designed for multiple underwater settings beyond the standard aquarium. Its compact form and waterproof rating make it suitable for a variety of indoor water features.
Aquarium and Fish Tank Use
Place the lamp along the tank wall or across the water surface using the suction pads. The blue light creates a calm ocean-like environment, while the white light provides clear illumination for viewing fish, algae, and decorations. The lamp helps highlight the natural colours of your fish and plants.
Other Water Features
Use the lamp in cisterns, rockeries, or pet cages to add accent lighting. The sealed design allows it to sit under running water or in static water features without risk of damage.
Benefits and Buying Value

This lamp offers energy-efficient lighting that lasts without frequent replacement. Its simple installation and two colour options give you control over the look of your setup.
Energy Saving and Long Life
With power consumption as low as 2W for the smallest model, the lamp uses very little electricity compared to traditional aquarium lights. The 5050 LEDs have a long service life, reducing the need for replacements.
Easy Installation and Maintenance
Installation requires no tools—just attach the suction pads to a clean surface. Maintenance is minimal; wipe the housing occasionally with a damp cloth to keep it clear.
