SANSI Grow Lights for Indoor Plants, Full Spectrum 36W Grow Light Bulbs (400 Watt Equiv) with Optical Lens for High PPFD, PPF 65.6 umol/s LED Energy Saving Plant Light for Indoor Growing Seed Starting

It was defective

I’ve tried many grow lights and this one is honestly one of the best for indoor plants. The light is very bright but still looks clean and natural, not purple or harsh. My hoyas and other tropical plants responded really well with healthy growth and better leaf color. It also doesn’t get too hot and feels much higher quality. Definitely worth the money if you love indoor plants.

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 ;)

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.

Lo compré porque en mi casa no entra casi nada de luz y me gustan mucho las plantas, algunas se me murieron y las pocas que quedaban dejaron de crecer, se etiolaron y en general no se veían bien. Ya llevan aproximadamente 20 días y ya presentan retoños, se ven más verdes, con brillo y las que tienen manchas más claras se están resaltando.Solo hay que tener cuidado de no exponerlas demasiadas horas porque se pueden quemar un poco las hojas o como en mi caso, que necesitaron hacer el cambio más progresivo.Lo único que no he podido evaluar es el consumo energético, pero vale la pena ver bien mis plantitas
