GlowTub Underwater LED Color-Changing Light 2.75in — Remote, 16 Colors & Adjustable Brightness

GlowTub is a cordless, battery-powered underwater LED light with a remote that adds 16 colors, adjustable brightness, and four lighting modes to bathtubs, spas, and more.

Designed for simple installation and safe underwater use, the GlowTub underwater light combines a sealed ABS housing, a strong suction cup mount, and a splash-resistant remote to create an instant ambient glow without cords. At 2.75 inches wide and powered by three AAA batteries, it fits discreetly in tubs, hot tubs, and decorative containers to highlight water, ice, or centerpieces.

How does GlowTub attach and stay in place underwater?

The GlowTub uses an extra-strong suction cup that mounts to clean, smooth surfaces like porcelain, acrylic, or tile. Its back cover accepts the suction cup and, when pressed firmly, holds the light steady during normal bathtub or spa use.

• Install the suction cup through the back cover and press to a clean, dry surface.
• Not suitable for inflatable or textured surfaces—best on smooth tubs and spa shells.
• Repress the suction periodically and remove when not in use to prolong adhesion.

What lighting options and effects are available?

GlowTub offers 10 bright LEDs across 16 color options with adjustable brightness, plus four modes—Flash, Strobe, Fade, and Smooth—so you can switch between high-energy effects and gentle transitions using the included remote.

• 16 vivid colors and variable brightness control for mood customization.
• Four preprogrammed modes for dynamic or calming light patterns.
• Remote control provides splash-resistant, instant adjustments from outside the water.

How is GlowTub protected against water and wear?

The light is built from durable ABS plastic and uses a double-seal waterproof system plus a secure rubber gasket to keep moisture out of the battery chamber. Proper closure and routine checks help maintain long-term reliability.

• Durable ABS housing resists impact and corrosion in wet environments.
• Double-seal system with rubber gasket—tighten the lid before use.
• Remove batteries and store dry when not in use to extend service life.

Where can I use this light besides my bathtub?

GlowTub's cordless design makes it versatile for indoor and outdoor decorative lighting: ideal in hot tubs, spa jets, fountains, vases, ice buckets, event centerpieces, and holiday displays where a compact, waterproof accent is needed.

• Perfect for hot tubs, spas, pools (smooth surfaces only), and decorative containers.
• Works well in floral arrangements, ice buckets, or as table accent lighting at events.
• Battery-powered portability lets you place it anywhere without cords or outlets.

Who is this for? GlowTub is well suited to anyone who wants a simple, portable way to add color and ambiance to baths, spas, and decorative water features—homeowners, renters, event planners, and hosts looking for easy-to-install, cord-free lighting accents. It’s especially useful for people who need a compact light that adheres securely to smooth surfaces and is controlled remotely without getting electronics wet. For best results, use on smooth, non-porous surfaces and follow the seal and battery care steps outlined above.
