hygger 32W Full Spectrum Aquarium LED Light with 10 Levels of Brightness, White Blue Red Green LEDs,6H8H12H Timer,RGB Light for 46-54IN Freshwater Fish Tank, Aquatic Plants Tropical Ornamental Fish

My power company does maintenance or line work where power is shut off for less than a minute but it normally is only a second or two. This light will shutdown and not restart when power returns. Unfortunately you have to wait until you reach the time of day you want to set your start time which can be a problem if it is while you are at work. More of a problem is when you are traveling and return home after a week to find your plants have had no light since you left.

Arrived without instructions and only partially packed. It just produces white light at various intensities with a selectable timer. You get what you pay for.
