Ⅰ. [Super Bright and Low Battery Mode] - DEEFSOUL diving light has 13 LED lamp beads. Compared with diving light with 10 LED lamp beads, the brightness is increased and the colors are vivid. 5 types of brightness can be adjusted to the appropriate brightness to create a comfortable atmosphere. When the battery is running out, the diving light will flash a faint red light as a reminder. Ⅱ. [16 RGB Modes, 3 Dynamic Modes, 3 Timing Modes, 5 Brightness Levels] - DEEFSOUL submersible light has 16 RGB modes and 5 brightness levels to create different atmospheres. 3 dynamic modes, FADE: gradually change the light color, FLASH: quickly change the light color, SMOOTH: slowly change the light color, three modes. 3 Time Modes, 2H, 4H, 6H Ⅲ. [Two Adsorption Modes and IP68 Waterproof] - DEEFSOUL diving light has two adsorption modes: magnetic adsorption and suction cup adsorption. There are 4 magnets on the back of DEEFSOUL. Four silicone suction cups can be attached to the back. Both adsorption modes are suitable for most surfaces. DEEFSOUL diving light has a blue waterproof ring. Tighten the light cover to achieve waterproof effect. Ⅳ. [21-Key RF Remote Control] - DEESOUL diving light has a 21-key RF remote control, all functions are arranged and marked on the remote control. The RF remote control uses RADIO frequency signal to control the diving lights. It transmits signals in a 360° angle. The operating range of the remote control is up to 30m in the air. Even if there are obstacles, the signal can still be transmitted accurately. Ⅴ. [Create atmosphere] - Underwater lights are not only suitable for underwater decoration, but also for various parties, nightclubs, offices, museums, shops, aquariums, festivals, weddings, Halloween decorations or Christmas. Due to the various installation methods, it can be suitable for various situations! (Apply to clean, smooth surfaces only. Not suitable for textured, tiled or matte surfaces.)
