Rechargeable Battery - The wireless LED spotlight indoor has a built-in 3350mAh lithium-ion battery, which can be used for 200 hours at the lowest brightness and 20 hours at the highest brightness, giving you a long-lasting lighting experience and saving you the trouble of frequent charging. 2. Unique Magnetic Function - Magnetic force makes installation easier. This indoor uplighting can be adsorbed on metal objects, or attached to the wall with 3M adhesive or screws. (included in the package.) In addition, this indoor floor uplight is made of metal and is stable enough to be placed directly on the floor or cabinet. 3. Two Control Methods - You can control the indoor uplights from across the room with the remote control (15 meters range). If the remote control is not nearby, you can also short press the touch switch on the lamp to adjust the color temperature (3000/4000/5000K), or long press to achieve 10% stepless dimming. 4. Countdown function - 4 countdown options (2/4/6/8 hours) can meet your daily needs. The built-in chip has a 24-hour cycle function. If you turn on the indoor LED uplights at 8:00 PM the night before and set a 2-hour countdown, the rechargeable spotlight will automatically turn off at 10:00 PM and turn on as usual at 8:00 PM the next day.
