Do you need a grow light bulb for your indoor plants? Maybe your current grow light left your plants in a stagnant state of growth. I experienced a similar situation with the 12 watt LED grow light bulb I was using and decided I needed something better. I ended up with the full spectrum Sansi 36 watt LED grow light bulb, which left my small plants and I impressed.
The Sansi 36 watt grow light bulb is a full white spectrum LED plant bulb. It’s a great grow light for small spaces, small indoor plants, and succulents.
Sansi 36w Grow Light– Great For Small Indoor Plants
Sansi was kind enough to send me their 36 watt full spectrum LED grow light bulb. I wasn’t really aware of the Sansi company before, but in case you didn’t know, they’ve produced one of the highest resolution TV screens in New York City’s Times Square. They also have a full product line of other LED products, so I get the sense Sansi knows how to make a good LED grow light.
My Time with the Sansi 36w Grow Light:
Although I didn’t know it at first, this full spectrum LED grow light bulb ended up being perfect for the small space in my house where I grow a few succulents.
I already had a cheap 12w grow light with a red/blue spectrum, and the succulents weren’t responding much to that grow light. They were pretty much stagnant.
The difference in the succulents after the first 1-2 days of installing the Sansi 36w grow light bulb was impressive. The succulent petals sort of “lifted up” like they were standing at attention, or as if they were awoken from sleep.
I continued to notice faster than normal growth in my succulents over the following month. It’s clear to me the Sansi 36w LED Grow Light bulb made a difference to those succulents.
If you know much about succulents you know they’re among the least demanding indoor plants. So I picked a small plant from my yard to see if I could grow it successfully under the Sansi 36W LED grow light. I ended up with a Marigold seedling.
Marigolds are a bit more demanding than succulents. They expect a lot more light and water than succulents to sustain their rapid growth. They go from seedling to flower in 40-50 days.
After ~30 days the marigold is doing very well under the Sansi 36w grow light bulb. I’ve kept it in a small grow cup to save space, but considering the environment it’s been given, the flower is doing very well.
I kept the Sansi bulb 18″ above at all times, and run the light for 8 to 9 hours per day. The bulb gets warm but not too hot to touch. Sansi recommends running the light for 10 to 12 hours at a time.
I eventually replanted the marigold into a larger bucket. I think the seedling cup was holding it back from growing further. It turns out I was right. I gave the marigold a larger bucket and it continued to grow and now looks almost ready to bloom.
Update: It finally bloomed, and still has at least one more flower on the way!
The orange color is really vibrant, really happy with how the plant turned out considering I only used tap water and the Sansi 36 watt grow light bulb.
Why the Sansi 36w grow light bulb performs well:
This is a great grow light for small plants, or even if you want to combine it with other grow lights to boost light intensity.
The spectrum of this grow light really separates it from other low wattage grow lights. What you’ll see in the image below is a true full spectrum.

White Spectrum
No matter what size plants you’re growing or what size grow space you have, spectrum is one of the most important features in a grow light. White spectrum has been shown to result in 12-16% higher tomato yields compared to red/blue spectrum alone (you can read more about white spectrum here).
Most of the small grow light bulbs on the market today still feature red and blue spectrum, so the Sansi 36w Grow Light bulb provides you an advantage on that front. If you read any of my reviews about larger grow lights for cannabis, you’ll see I always prefer the white spectrum over red and blue alone.
120 Degree Lens
Another nice feature on the Sansi 36w LED grow light is the 120 degree lens. That lens helps spread the light out more evenly across the plant canopy, instead of focusing the light all in one direction, which can result in burned leaves.
Infrared wavelengths
When you’re browsing for a grow light for indoor plants, among the sea of cheap purple spectrum bulbs, you’ll likely have a hard time finding an LED grow light bulb that includes infrared wavelengths.
Infrared in small amounts, like what’s included in the Sansi grow light bulbs, is beneficial to the formation of your plants’ stems. Since the infrared is naturally damaging to a plant’s cells, small amounts of exposure can activate the plant’s natural defense mechanisms which result in thicker, more well defined stems.
If you plan to use these bulbs to boost light intensity in a cannabis grow space, we know that infrared benefits cannabis in the same way.

How high or far should I hang the full spectrum LED grow light bulb from my plants?
Sansi’s 36w full spectrum LED grow light bulb covered roughly 12-inch x 18-inch space for me when it’s hanging from 18 inch height. I suspect the smaller bulbs will effectively cover a slightly smaller space.
I’ve seen other owners place the light much farther away than the recommended 18 inches and claim their plants are doing well. Whatever works for you is great. I personally tend to prefer the standard 18″ height.
If you’re growing a fruit or vegetable bearing plant, you should you keep your grow light closer to the recommended distance to ensure your plants are getting enough light intensity.
Consider purchasing multiple LED grow light bulbs if you’re growing fruit or vegetables.
One Sansi grow light bulb was enough for my succulents and flower when it was hung at the correct distance.
But you may want to consider purchasing multiple grow light bulbs if you’re growing fruit or vegetables.
The main reason is that fruit and vegetable bearing plants require more light energy than regular flowers and houseplants. If the general area is well lit, that doesn’t necessarily mean your plants are receiving enough light.
If you’re growing fruits or vegetables, I’d recommend purchasing 3 or 4 of these full spectrum grow light bulbs to ensure your plants are receiving enough light. This way your plants are receiving Sansi’s high quality light spectrum as well as enough light to produce great fruit and vegetables.
Just remember that these are grow light bulbs are geared towards small indoor plants. If you’re growing larger plants, you’ll want LED grow lights that cover a large area and emit more intense light. You can read more about the best grow lights for that scenario here.
