Lights come on automatically each day for the desired time (8, 16 or 24 hours) it has 2 brightness levels and a timer. I really like the timer option which allows you to adjust how many hours you'd like the light to stay on for.
The height is adjustable and the lights swivel to position as needed. The rod is sturdy and easily adjustable. It adjusts for small or tall plants.
It arrived quickly, the stick is telescopic. Love the soil spike, keeps it secure especially in airy or bark heavy soil. Now have tons of blooms on the peace lilly and very vibrant leaves.
The size and timer function of these are great, theyre just not good lights. Maybe the brightness isnt strong enough, or the wavelength is off. None of the timer settings are accurate.
Power supply shows that it's not even close to 300w worth of lighting. Specifications for the listing are a downright lie.
