SANSI Grow Lights for Indoor Plants Full Spectrum, 36W Grow Light Bulb (400 Watt Equivalent) with Optical Lens for High PPFD, PPF 65.6 umol/s LED Energy Saving Plant Light Bulb for Seeding and Growing

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.

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.

I have a large banana palm in my living room. It did not have enough light. I got a full spectrum regular sized 9 watt grow light bulb. It was wholly inadequate. My plant struggled and struggled to produce stunted leaves. Then I got this bulb at 36 watts and my plant is so happy. New leaves started growing and pushing upward after only 5 days of use! Totally worth it!

I love this bulb, my plants love it even more! I purchased this in Sept of 2023 & it suddenly went out. Under normal circumstances I would’ve just bought a new one, but I’m struggling financially. I saw bulb was still under warranty and company assistance was absolutely a dream to work with! They made the process simple and new bulb on the way! They’ve earned my business for life! Thank you!!

I love these light but they only last about a year or so… I only use them over winter but they are on for 9-12 hours a day… they work great but the warrant is a pain to use and in most cases I don’t get the replacements. For the money they work well. I use them exclusively on lemon trees but I have about 4 per plant.

Great light I wish I would’ve gotten the brighter one because of the amount of plants I have… buying from them again!!Highly recommended and it has a nice warm color

10 watt will only work super close to your plant. Sansi is good but opt for the higher wattages

I really love this light! It's really bright and more of a warmer white than a cool white. My plants were quickly leaning towards this bulb the first day and have been thriving every since. Would definitely buy again.
