Better than expected; which is rare lately. The cord isnt limited set in distance apart from the lights, you can adjust the cord length between each light which is very nice.

The lights are both wired to one control switch which means that the wires of the lights can only stretch to about 3-4 ft from each other and can only be set on the same timer.
You can set times for 6,12, or 16 hours.
The lights come with stakes to place in a pot and reach about a foot above the dirt so they wouldnt work great for tall plants.

Lastly they are quite broad lights and cover a lot of area if you have multiple plants near each other.

Half the light stopped working and burned my plants up.

Read some poor reviews however my experience has been great. The product works perfectly and is half the price of the brick & mortars.

I think the lights were very good and did their job keeping the plants happy with light. I did not like that the bulbs die after 4 months of use at about 10 hours a day. Not happy about that, but am glad I can replace the bulbs with something else. of continued use. It's only a matter of time the second one will go, I'm sure! I am hoping to replace the bulbs with something a little more reliable.

The advertised ppfd chart shows a better read out than what the product actually offers. Claims are grossly actualppfd is hundreds lower. . Also the exact same model at same time is $100 cheaper on the vivosun website than at the vivosun ecogrowhawaii.com store. Research this company on Google and reddit and look at many of the 1 star ratings on ecogrowhawaii.com. There are over 5000 ratings. They try to justify the power output by environmental impact. Seriously.... bad company.
