SANSIGrow Light Bulb with COC Technology, Full Spectrum 15W Grow Lamp (200 Watt Equivalent) with Optical Lens for High PPFD, Perfect for Seeding and Growing of Indoor Plants, Flowers and Garden

I had a very special plant that was planted by my Dad before he passed away, it was growing great. Then the one day I temporarily moved it, was not good. It ended up looking like it was all dead & had no hope. But I didn’t want to give up on it because it was special,I did a lot of research & looking what I could do to help my Aloe plant that was once beautiful & big, now dead, sad, hopeless looking. I said what the heck it can’t hurt to get a bulb to help it because hey it can’t make it any worse. But I wanted one that Didn't get hot & this one don’t . And Oh My goodness, to my surprise BEST money I have ever spent.!! I could not believe my eyes that this bulb brought my plant back to live. The durability is way more then I expected, I just screwed this special light bulb into a clamp on lamp I already had on my desk. I wanted to wait a while before I did a review to see if it would still work & if my plant still making it.I order light bulb & started using in September 2023Today is December 2, 2024 and light is still working & my plant is thriving. Highly recommend.

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 wanted a bulb for my hanging light above my houseplants. Wow, is this one bright. In order to look up, I need my eclipse glasses! Pros: it's led, and though I really can't say what any specific thing in my house is using electrically, they are supposed to be energy efficient. The light is bright enough that it shines through the top plants and onto lower shelves, adding light there as well. My plants are showing beautiful colors and growing well. Con: It's bright enough that it will burn leaves that are directly under it. I have found they need to be at least 15" below to not be burned. plants to the sides are fine. I have only had it a couple of months and will update if it burns out quickly, but so far, I am very satisfied. It's the best plant bulb I have found yet!

Second sansi bulb purchase. It's definitely nicely made, much brighter than similar wattage grow bulbs I've tried, has a wider spread of light and produces less heat. Can't beat a 5yr warranty either. The only thing I'll mention is that the light temperature is a little on the greenish side compared to others, but the CRI seems to be pretty good. I'm probably just used to seeing plants under my old pinkish colored lights.

This light works perfectly for adding supplemental lighting to the plants in my basement. What I love about this unit is that it’s specifically designed to fit the ceiling housing for my lights, making installation seamless and hassle-free.The lights get hot, but they’re designed with space to allow proper breathability, preventing overheating. The 4000K daylight spectrum effectively mimics natural light, promoting plant growth across all stages. The patented ceramic heat sink technology also inspires confidence in durability and longevity.This is an excellent choice if you're looking for efficient and plant-friendly lighting with reliable heat dissipation.

Within a couple weeks, indoor plants that were struggling with a prior grow light started putting on new growth. Only thing that I would note is the bulb is pretty heavy so make sure the lamp can handle it.

The media could not be loaded. I ordered this light 3 months ago and it has been working great. I used it fot my potted lemons and guava during the freeze and Mt plants are still thriving. Now I am growing guamuchiles from seed and they are also performing amazing on them. So wether you are looking for a grow light for grown potted plans or young seeds this light will work.
