Lights are lightweight enough to be mounted on the underside of a shelf. Work well for seed sprouting (herbs), baby plants that are rooting, and even provide enough light to produce a fenestrated monstera leaf.

The timer is great! The timer has 3 settings. The plug gets a little warm to the touch after the lights have been on for a while. The timers make it so easy and provide a simulated daylight environment for the plants depending upon their needs.

The power adapter simply does not work anymore. These only lasted 7 mos on 12 hr timer! Would not recommend for the lack of longevity.

I love that they’re full spectrum but also pink- it creates a nice ambiance while providing light to my plants. These work super well, beautiful yellow light, but they do get pretty warm, borderline hot. These are great and give the option to either z...  Read More

The lights all connect together on 1 convenient timer plug (16 hours on, 8 hours off) they’re so easy to connect several in or manually switch off. I have them plugged into a smart timer to keep them on overnight.

These shelves have 8 barrina 24 inch t5 led lights chained together on a timer 15 inches from the shelf below. Placement is tiny tim toward the back inner corner for support and some room to sprawl toward the shelf center and forward gold nugget to th...  Read More

They all survived, so they're a bit studier than their very light (not-heavy) construction suggests. I use for semi mature plants and have them about 12 inches from the top of the pots and my plants are thriving underneath them.

Some bulbs only give off 1000 lumens. It takes 8-10 of theese (80-100watts) to replace 2 t5s. This is not what the par value is average across a canopy using all 8 lights.

It is entirely aggravating. Can't return them. Absolutely frustrating. This is not acceptable. Too much hassle to return.
