    • Nice grow light! (36W)
Wattage: 36.0 Watts
Review Image by jizared

Review Image by jizared
I have a small 4 sq/ft area indoors that will be used to eventually grow 3 plants, all Willow Leaf Ficus Bonsais (that's their common name). The plants range in size, but none of them will take up more than 1 sq/ft individually, and the one in the picture is much smaller than the other two that will be put under the lights later. For now, there is a single, quite small Ficus (as you can see in the picture). They love light, the more the better. My setup includes 2 Sansi 36W full spectrum 4400K bulbs and a single 60W 5000K corn LED bulb (about 9" long). The Sansi bulbs are white with a bit of a yellow cast to it, indicating the larger percent of red spectrum than blue (as the spectral curve shows). However, there's a nearly perfect amount of blue for growing lots of foliage (not to mention the rest of the spectrum which is very important also). I will use them to grow foliage, seeing as how my plants don't bloom. The other LED, a 60W 5000K corn bulb will be hung vertically in order to fill in the gaps with high quality light (leaning more towards the blue spectrum) hitting the sides and lower branches of the trees. My initial thoughts upon receiving the bulbs and powering them on are first, are that they are quite heavy and extremely well built. I understand the price since it is a full spectrum bulb (with the spectral curve and data to prove it) and has very high build quality. Upon powering them up, they comes on immediately to a color that is slightly more yellow than I expected, but looking at the spectral graph, it makes sense, due to more reds than blues. Both bulbs are identical in build quality and color of light. Seeing as how I'm only using one Sansi bulb right now along with one small Bonsai tree, I'll give you my observations with regards to light output based strictly on lux. I have an app on my phone that measures lux. Granted, I know plants use energy based more on PAR, a full spectral curve, etc., but the amount of lux still gives me an idea of how bright the light is in certain areas compared to other areas, but it definitely doesn't tell the full story of how it affects plant growth. My trees are fast growers for Bonsai (meaning they still don't grow fast compared to a sunflower, etc.) and love full sun outdoors. Unless you are growing plants that don't require much sun, (such as houseplants, seedlings, cuttings, etc.) I personally wouldn't hang it 20" from the plants, as that seems a bit far to get the excellent growth I require. I measured the lux directly under the LEDs, above, below, and to the sides, at various distances from the bulb. For rapid growth, I wouldn't count on this light to cover 4.2 sq/ft and still grow extremely quickly. Don't get me wrong, it has decent light coverage at 12" and 20" away, but getting it to around 6" will give you massively more light if you are inclined to do so, especially for flowering plants or plants that generally require huge amounts of intense light. My current light in the picture is 5-6" from the top of the Bonsai. The light intensity at that distance is extremely high. With three plants I'll use my 2 Sansi 36W lights directly over the 2 larger plants when I bring them in (at 6-12" away depending on the coverage). The smaller Bonsai (pictured) will get less direct light from the 2 Sansi bulbs and direct side lighting from my 60W vertical LED. I have a total of 132W of LED lighting in a small area that will allow the plants to grow at their absolute best and fastest. One of the Sansi 36W bulbs would do okay for the three of them. 2 of these bulbs would do quite well, I'm sure. Adding the vertical bulb will really allow every part of the Bonsai trees to grow extremely well and to their potential. I realize, however, that this is total overkill for most people. Final words: This is a nice light. If hung at 12-20", you'll be giving enough usable light to cover a large area, but don't expect incredibly fast growth from all types of plants. When used at about 6-10", you'll be giving your plants tons of light, with the parts of the plant(s) directly under the LEDs getting BY FAR the most light. These LEDs don't spread wide. They are very focused. I like that fact and use this to my advantage. In my grow area, my three bulbs will be giving huge amounts of light to three plants coming from every angle. For those who don't need tons of light, this light will absolutely cover the space that it is advertised to cover. Verdict- 5 stars. Oh, and lastly, these bulbs give off impressively little heat and no noise, so using them 5-6" from my plant does not pose heat issues nor any light bleaching, and of course they are silent. I have a small oscillating fan on low to give airflow to the plant, but even without it, I can touch the LEDs after they've been on for 10+ hours straight. They're warm, but not overly hot to the touch and this is with simple passive cooling! Awesome lights! Update 1: My Bonsai, which tends to drop lots of leaves when taken from outside to inside or has any change in environment, hasn't dropped a single leaf. That comes down to the nice indoors temperature, but mainly the light, which is giving it everything it needs. I'll update further as these lights get more usage. So far I'm very impressed. Update 2: I brought my other 2 (much larger) Willow Leaf Ficus trees inside the grow room (as the new pic shows) for a total of 3 trees. There's a Sansi 36W about 8-10" above each large plant and a 60W vertically hung to get light to all of the foliage under the canopy. 132W of light for strictly vegetative growth in a ~4 sq/ft area. Overkill, maybe? But nothing is too good for my Bonsais, and these lights are doing them justice for sure. Update 3: I decided to rearrange my grow space and have BOTH Sansi 36W lights directly over the same Bonsai tree (about 18" L x 14" D x 16" H). So this tree takes up only 1.5 sq/ft, give or take. Additionally, each light is only 6" from the top of the canopy. The two lights only have 5" in between their hanging locations. This is due to the hyper-focused 60 degree LEDs that put massive light on a small area of a plant, especially when put so close (again, that's what I was after). So now the tree is completely covered in a freakish amount of light. The lux meter I use is actually reading higher numbers than it did when I used it on the plant when in full sun (during July in Southern California). The reason for the change-up is because I fully defoliated the other good size tree, so it doesn't need near as much light right now. The growth I've seen on all three plants has been nothing short of spectacular, and this is in a short time frame, and we're talking about plants in very small pots. The 17 hours a day of direct light helps a lot, but I'm still shocked at how amazing the growth has been. Again, the big tree in particular is growing WAY faster than when it was in 7 hours a day, extremely intense sun. I also have a 60W vertically hung (360 degree light) corn LED bulb hitting all 3 trees, but it's affecting the big tree under the canopy since it's hung much lower. It's clear the massive canopy growth is due to the dual Sansi 36W bulbs. All of the red and yellow/bronze colored leaves are new growth, of which their is a ton, all grown in a very short amount of time. I realize this lighting setup is far from the norm, being so close and having such concentrated light (with no light bleaching or burning at all). However, since I want new growth to fill in a portion of the Bonsai, this is clearly the best and fastest way to get that growth. For all of those wondering about hanging the light closer, 6" is no problem for me (indoor temps are around 75 degrees, canopy is about 80 degrees, and all I have to reduce the non-existent heat is an oscillating fan on low). These Sansi lights continue to shock me with their power since they're only 36W bulbs and they're outperforming the SUN situated how I have them! 5++ stars reconfirmed! Edit: It’s been a while and I haven’t put many hours on these bulbs over the years. Less than 1000 hours on 4 36W bulbs and every single one has had 1-2 diodes go out. I get why the longevity rating on these is so low. They’re nice to use and work well, but their reliability is poor, unless things have changed. I’ll move to a more reliable brand, like Spider Farmer. More expensive, but much better coverage, output, and reliability. ... show more

    • comparing 15W vs. 24W vs. 36W
Wattage: 36.0 Watts
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. ... show more

We bought this bulb in 2018 to grow plants inside our house in wintertime. It has worked great for 10 to 12 hours per day. But, it finally stopped after about 4 years of service. Sansi honored the 5 year warranty, but asked that I pay $15 for shipping since it beyond the return period. I agreed and paid in advance. The first shipment was crushed by the carrier. So, I emailed Sansi and they sent me another. Great product! Kind of pricey, but it lasts a long time and works well as an indoor grow light! ... show more
