What’s the advantage of SANSI grow light bulb?
Hollow structure design
The working heat of the lighting device is quickly transferred to the air through natural convection, and the heat dissipation is faster and the service life is prolonged.
SANSI light intensity is always 3-5 times higher than others with the same power. Sufficient light intensity ensures healthier plant growth and prevents plants from becoming too elongated (manifested in plants having long, thin stems without proper flower or fruit development).

Very good light very happy plants *36W lights are heavy!*
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!

Excellent bulb, my plants seem to like it. Larger than I thought.
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.

Worth it for plant parents!
This is a great product! My home has very few windows with only a little light coming through, so grow lights is a must for my plant babies. I have bought other brands of grow lights of lower wattage, some which can be seen in the bottom of the photo, and they have nothing on the Sansi 36 watt grow light. Within a week of using this light, I have seen my plants go from content to thriving! Most notably, my monstera deliciosa is sprouting a new leaf and its aerial root that I had placed in a moss pole has grown nearly 5 cm. I’m definitely going to want another light from Sansi. Until then, my cart of plants is going to be overcrowded around this bulb🤣The bulb does not overheat. I am able to touch it and move it if necessary without burning myself. It is one of the brightest lights I’ve ever seen, and it makes the colors of my plants pop whereas other lights I have do not.

comparing 15W vs. 24W vs. 36W
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.

Very good grow lights, plants love them
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.

Carnivorous plants love it
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 🤌🏽

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 😉
