SANSI Grow Lights for Indoor Plants, Full Spectrum 24W Grow Light Bulbs (300 Watt Equivalent) with Optical Lens for High PPFD, Natural Daylight Efficiency Plant Lights for Indoor Growing Seed Starting

I’ve been using the SANSI 34W Grow Light for about 4 years now, and it has been absolutely awesome. This light has allowed me to grow massive, healthy plants completely indoors with strong growth, great leaf size, and consistent results year after year. The light output is powerful for its size, energy-efficient, and reliable long-term—I’ve never had issues with it burning out or losing intensity. It’s perfect for houseplants and makes a noticeable difference in plant health and growth, especially if you don’t have ideal natural lighting. If you’re serious about indoor plant growth and want something dependable that actually works, I highly recommend the SANSI 34W grow light. It has more than proven itself over time. 🌱💡. Last week I had to use their customer service for blown bulbs and it was top notch service and hassle free replacement.

I've never used a grow light before but was experimenting with growing some herbs indoor. The bulb is fairly large and heavy and feels very sturdy. It looks like something out of a scifi movie. I probably should have ordered a larger lamp but it fits in a standard lamp size and socket but is a tight fit as the bulb is large. It gives off a very pleasant and bright light which is not harsh, hot or irritating. I am not an experienced plant grower but so far I have seen a very noticeable jump in the health of my plants under the light. I don't get a great deal of sunlight where my plants are and they are certainly improving with the presence of steady light. I have it on about 10 hours a day with no issues so far. Highly recommended.

The very bright 36W light keeps making my plants happier and happier since the natural light is fading away as winter approaches. I pair it up with the $19 Ikea desk lamp, and they look gorgeous together. The lampshade is never too warm; I can always touch it. This light is quiet while it works a lot. Even though the first order included the wrong light, the second order was alright. One thing to keep in mind: they are heavy and huge!

So at this point I have purchased 3 different sizes of Sansi grow lights, 15, 24, and 36W over the past 3 or so years. They are all excellent bulbs, so bright it is annoying to have them pointed at your eyes. I was attracted to the Sansi brand thanks to a few online reviews, especially some that used their own spectrometers to confirm that these give a proper full spectrum including a little UV. I like to think my bird likes it too since she can see UV! I wonder if the UV helps with winter depression? In summary: I recommend the 15W for individual low-light houseplants, like a mini moth orchid, succulent, or mini African violet. I recommend the 24W if you have a small collection of plants. I recommend the 36W if you have a medium collection or want to grow a fruit/veg.. I recommend multiple 36W if you have a large collection or a small tree, but if you have that many plants you probably already know what you are doing. ;) Of note: Of note is that the bulbs do get hot after running about 12hrs a day, so it hurts a little to touch the diodes directly, and do not put them in lampshades that would restrict airflow. They do not run hot enough to affect the plants whatsoever though. I have to put my hand 1 inch away from the diodes before my hand detects it as being hot. I think the passive vents do a great job of directing the heat up and away rather than down towards the plants. Also of note is that there is an audible coil whine when any of the bulbs are on. This is not loud or obtrusive (I regularly have one about 3ft from me when I am studying), but it is noticeable if you have young ears. It is also worth noting that the light cone is fairly narrow/focused, so plants directly under the bulb get significantly more light than those around the periphery. This is not a bad thing; it means more of the light is efficiently being beamed on your plants instead of scattering around the room. Below is a comparison of my personal experience with the 3 sizes: The 15W was excellent for a tall desk lamp with a few mini African Violets huddled around it. It was insufficient for outdoor plants that like full sun such as Egret Orchids. I upgraded to a 24W once my plant collection grew to the dozen mark, so I could have a larger illuminated space to work with. Of note is that this bulb was visibly warmer in color than the 15W or 36W. It reminded me of a nice incandescent bulb's glow. I am not sure if this is a consistent thing with the 24W or if it was just my bulb. Otherwise, the 24W was actually my preference for houseplant use with my personal setup. I bought the 36W for a friend to use in a fish-tank sized terrarium, again, for the wider radius able to cover more plants. It is strong! It would be interesting to see if more outdoor semi or full-sun type plants would be satisfied by the 36W; it is a very bright bulb. As is, my low-light houseplant African violets needed to be placed an extra foot away from the bulb to stop from getting sun burn or bleaching. I would mention that the bulb is quite heavy at this point, so if you are using a flexible goose-neck lamp, make sure it is nice and stiff or it might sag under the weight. Tip: If you have a proper light sensor, it is super handy when setting up your plants around your new bulb. I resorted to the free Arduino Science Journal app on my phone to compare light intensity (in lux units), and using recommended lux levels from google for my particular plants. I get about 22K lux directly ~1ft below the 36W bulb, for example, but about 8k lux ~2ft directly below. I currently have my mini african violets arranged in a ring of ~2ft diameter, about ~1.6ft below the light. This gives them the recommended ~7k lux of light according to google.

they are fantastic grow lights. they work well for my plants. there is just one thing to keep in mind, no matter how long sansi says they will last, the truth is they will last about 12-15 months. still I would reccomend them as they are close to natural light and the plants do well with them. Whatever you do don't buy the red and blue ones, they don't really work well for plants. So I would give five stars if the bulbs lasted more than a year.

Very nice and bright lamp, girlfriend bought it first and it was so strong it sunburned a few leaves on a flytrap haha. HOWEVER she had it pretty close, like wayyyy closer than my image. As seen in the image I read it’s not the best idea to keep it in a hooded lamp because it is vented to increase its lifespan but it doesn’t make the lamp shade itself too hot which is good. The 36W is so bright it can easily light an entire bedroom, uncomfortably bright at times and even indirectly do not try to look the bulb head on. The bulb doesn’t get super hot to be a concern to my plants and what warmth it does give off is a benefit to grow especially indoors where mold can be a concern if you have wetter plants like mine. This bulb also has a 5 year warranty and estimated 25,000 lifespan which is pog 🤌🏽

I have some plants at work, and they don’t thrive with only the fluorescent overhead light. This light is very bright and offers a balanced, natural white light. I have seasonal affective disorder and having this one right next to me at the desk has kept it at bay this year. Easy to use and install-it screws into a standard lightbulb socket like a standard bulb. It gets hot, so I would recommend getting a lamp with vent holes to use it with.

It was defective

Me encantan estás lámparas! Tuve que mudar por un tiempo las plantas del jardín a una habitación separada porque los gatos estaban acabando con ellas :'( Obviamente estando ahí no recibían prácticamente nada de luz solar ( excepto por una ventana pequeña). Compré varias marcas de luz artificial y ninguna les funcionaba, hasta que finalmente encontré esta marca en Amazon. Compré tres focos de 36w pero para algunas plantas eran demasiado potentes y tuve que alejarlas un poco. Pero para las plantas que requieren más luz estan perfectas. Incluso las plantas con flor empezaron a florear de maravilla, mejor que cuando estaban en el jardín. Sin duda una de las mejores compras para plantas en cuestión calidad-precio ;)

Received as promised.

Bought this bulb few days before, now its gone, not working

Para poder cultivar plantas dentro de casa sin los rayos solares
