48 LEDs Full Spectrum Grow Lights for Indoor Plants, Height Adjustable, Small Black Halo Plant Light with Base, 3 Light Modes, 10 Brightness, Auto Timer 3/9/12H, 2 Pack

IMO, I got this one, it has a timer with 12-hour auto shut off LED and you can change the brightness and color temperature and it's pretty cheap, https://a.co/d/0bxWWprm
