Suitable for various humid and dry environments, such as pool lighting, pond lighting, boats, fountains, aquariums, fish tanks, vases, flower pots, waterfalls, bathtubs, hot tubs, corridors, basements, and garages. Can be used for weddings, events, parties, and as decorative indoor and outdoor lighting, mood lighting, or night lighting. 【High-frequency remote control, remote control distance up to 5 meters】: The LOFTEK underwater lamp is equipped with a high-frequency remote control, providing a longer remote control distance, up to 5 meters in the air and 2 meters underwater. The infrared remote control has an effective range of 60 cm, allowing one remote control to control multiple lamps without having to point the remote control directly at the fixture. We use this upgraded RF remote control, which effectively prevents signal blocking in large pools, deep pools, or when placed against a wall. Note: Pool water absorbs a significant amount of signal. Make sure the distance between the fixture and the pool is within 5 meters (including water surface and air gap). [16 colors, multiple options, dimmable underwater pool lighting]: Optimized 16 dynamic colors and multiple dimming modes offer more options, creating a comfortable and pleasant atmosphere. Its versatility clearly distinguishes it from many other pool lights on the market. This versatile indoor and outdoor pool decoration is ideal for bathtubs, ponds, swimming pools, fountains, ice buckets, vases, pedestals, flowers, aquariums, showrooms, display cases, central areas, cabinets, museums, shops, aquariums, pumpkin lanterns, and hanging paper lanterns. It is also ideal for illuminating glass vases, bowls, or other water-filled containers, transforming an ordinary bowl into a beautiful and exciting table setting, commonly used for parties, celebrations, and weddings.
