1) Remote control with timing function: One remote can control multiple flame lights at the same time (control range: 9.8 - 16.4 ft). The flame light provides four timer options (1/2/3/4 hours off). This is a one-way timer—the unit auto-off after the set time and must be turned on manually. The unit also offers multiple brightness levels. 2) 4 modes with gravity sensing: Realistic dancing flames, soft slow breathing flames, warm constant light, and gravity-induced mode. The LED software creates a realistic flame flicker, like outdoor flame bulbs. Gravity sensing ensures the flame moves from bottom to top even if the lamp is inverted. 3) Magnet base and hanging hook design: An independent flame light fixture without a base or cables. Flip-out hanging hook and a magnetic base allow attachment to metal surfaces, enabling placement anywhere to create a welcoming ambience. 4) Long standby and USB rechargeable: 1200 mAh rechargeable battery lasts up to 20 hours in flame mode after a full charge (charging time about 4 hours). It can also be powered via USB from a computer, power bank, or USB charger. Ideal for home relaxation or festival decorations such as Christmas, Halloween, birthday parties, and Valentine’s Day.
