Very pleased--already have a second one.
This light worked perfectly for the space/shelving I have. I have been starting vegetables indoors all my life, starting with my grandparents when I was a child. As an adult without fancy grow lights like they had, I've always struggled getting the seedlings to grow straight and tall and strong enough to be planted outdoors without issue. This year I finally committed to a light, which very quickly became two lights as the first one was doing such a good job.They are set up on a narrow Omar shelving unit from Ikea (the shelves measure ~18"x14") with a timer to ensure consistent amounts of light each day. My tomatoes are growing faster, straighter, and taller than I've ever managed in my adult life. As my plants get bigger before outdoor planting season, I plan to increase the spacing between shelves. I do not have the wires and hanging hook attached. Instead I'm using the four clips (that attach the wire to the back of the light) to clip the lights directly to the wire shelving. This also has the added benefit of warming the seedlings above them, as they do give off some heat--not much, just enough to be a comfortable warmth for sprouting seeds above them. The light is a little wonky to get used to having in the house; our kitchen is a strange purple/pink in the evenings when there aren't any other lights on. I didn't want to commit a big set up like my grandparents had (they started dozens each of several types of vegetables every year), and I wanted something that would be small, dismantle-able, and easy to store. Super-affordable was also a hope, and these were very budget friendly for us. The size of this light is perfect for my needs. Depending on your set up, your level of commitment/space, and quantity of seeds you plan to start, you might need something bigger. I currently have 9 tomatoes, 4 cherry tomatoes, 4 cucumbers, 4 zucchini, and 4 bell peppers sprouting/growing; I just started some flowers this week, too, since the vegetables are getting big and strong so quickly. These lights are working well enough for me this year that I plan to get more for the other Omar shelves next year so I can start more flowers indoors, too. I am very pleased, would buy this light again, and have already bought this light again. Happy planting!

THESE ARE GREAT
These lights are so good! I am using them for my succulents. I bought them to keep my plants inside over the winter, but am actually now using them for the baby plants that can't handle the sun, and for propagating leaves. The progress on my plants before putting them under these lights was very slow. It has been 5 days now. My propagated leaves have made a ton of progress for what I'm used to, and my baby plants that were looking rather questionable are quickly growing, and look so much more full! I can't recommend this light enough, I actually bought 2! I didn't expect to love them so much so quickly so my before photos are not good quality but I will try to remember to update in a few weeks with some pictures.

Only 50 watts, good for beginning seed
I actually needed a bigger wattage I'm my specific case, so this light didn't work well for my specific case. I will say it would be good for someone starting out seeds. Very durable and reliable.

Kept high light ponytail palm happy all winter indoors
I have a couple plants that can’t stay out all winter so in they come. However they used to get leggy from lack of sunlight. Our house is on the north side of a big hill - not enough winter sunlight makes it through the window. I decided to get artificial lighting to supplement. I have 3 of these lights hanging in the living room controlled with an Alexa friendly switch programmed to turn on in the morning and off in the evening. They are light in weight and were easy to hang. The plants do great now they have enough light! The lights don’t get hot. At night they cast a pretty purple color too.

Decent led grow light 50w gets you in the grow seat .
I got this light becouse i needed a way to grow wee without having to put my girls out side used this ufo led and its ok for what you get 50w i moved up to a ajustable led with veg and blossom control etc my new led is rated for 1000w but this one is good for seedlings and veg and its good for tight space place easy to hang and one button switch, boom your in if you need more fast grow then you need more wats .....hope this helps someone looking to get a small led grow light .

Wow, works amazing for lettuce and herbs. I just ordered a 2nd one.
I was a little skeptical, but with the reasonable price, I tried out this grow light. I like to start vegetables indoors from seed, so that in April I can load my garden with 8" high healthy vegetable plants that I do not have to spend like @ $3 for singles at Home Depot. My older potted thyme and marjoram grew like crazy under the light, with a timer turning it on for 14 hr/day. My seeds did really well too once sprouted, with lettuce, chicory and Italian kale doing especially well. You should make a grow box by taking a really big box and lining it with aluminum foil. Next year, I will definitely grow fresh lettuce and spinach in my basement over the winter. The UV and the IR LEDs will look dim, but they are working just fine. Our eyes cannot see that light spectrum, so this is why they look dim. However, do not look at these any more than necessary, since those spectrums are not healthy for our eyes (but they are great for plants). This is an economical grow light. The pot-heads probably won't like it because it is small and really tuned for vegetable growing, not dope.

Not strong
I purchased the 50W LED Grow Lights Bulb from Osunby expecting great results for my indoor plants. However, I was sorely disappointed with the performance of this product. The light emitted by the UFO 250 LEDs was not strong enough to promote healthy growth in my plants. I found that many of my seedlings failed to thrive under this grow light, despite following all the recommended guidelines for usage. Furthermore, the full spectrum light claimed to support vegetative and flowering stages did not seem to have the desired effect. My plants did not show the expected progress in these stages, leaving me frustrated and dissatisfied with my purchase. Overall, I would not recommend the Osunby UFO 250 LEDs Grow Lights Bulb to fellow growers looking for an effective indoor lighting solution. Save your money and invest in a more reliable product that will actually deliver the results you are seeking

Ok, but not great
The light is constructed well and works as expected, but I wouldn't expect them to last a long time and they are not as bright as I had hoped. I bought two of these about 2 years ago. At this point one has completely died and the other is partially gone. The leds stop working in sections. I have used them every day so maybe I am expecting too much, but the description says 50,000 hour life span. I have used them about 10,000 hours. That's only 20% of their rated life. The other issue I have is with the light intensity. You need to keep these very close to the plants to be useful. For about the same money you can buy a 4ft 2 bulb LED fixture that puts out a lot more light. The plants don't seem to care about the color - more light is better. I have grown a wide variety of house plants and hydroponic vegetables using both lights and the 4ft fixtures always work better, even for starting seeds. For a single plant and limited space these would work fine. For a larger grow area look for something bigger.
