Brighter and Warmer than other lights
I have been using GE grow bulbs for years, but i realized they are only 9 watts when I saw all my plants stretching out and getting leggy from not having enough light. considering they were directly under lights, I figured the GE bulbs weren’t cutting it. I saw people online recommended sansi so I decided to start investing in them one by one. I got my first one today and I have to say I am liking it already. you can tell the difference in this picture. Sansi is on the right, GE is on the left. I wish I had known about sansi before wasting my money on the GE bulbs, which will probably get gifted to friends now because I can’t return all of them. It may increase my electricity bill (we’ll find out next month) but if it keeps my plants healthy its worth it!

Huge growth!
I love Sansi bulbs. I think they really make a huge impact on how well your plants grow. So far mine have lasted a long time so I stocked up during the prime day sale.

Great fit for a Fluker's Repta-Clamp Lamp, Heavy Duty Clamp Light
Great grow light! Using with a Fluker's Repta-Clamp Lamp, Heavy Duty Clamp Light. Great fit! This bulb does not get hot! Jade plants and Cactus are happy with this set up 10"-12" away from the plants. People who complained about this bulb getting hot have no idea what they are talking about. Incandescent, Halogen and CFL's get much hotter! Would recommend!

Who Needs Actual Sunlight?
First off, this company has incredible customer service! My first bulb broke as soon as I tried to install it (defective lamp, no fault to the bulb). I immediately reached out to Sansi support to see what my options were and they quickly replaced it for free. I had the replacement within a few days of sending my first email. The new bulb has done a great job keeping variegated plants growing in the darkest corner of my bedroom. It is incredibly bright and paired with my Barina T5s on the opposite wall, I no longer use my overhead light at all. I mainly wanted a good light source for my Thai Constellation and Ruby Ficus Elastica, which are doing great! Of course, all of my other light loving plants are also growing well with strong variegation and no legginess. This light does put off a decent amount of heat, and I have burned myself bumping into it. If you're not as clumsy as I am, might not be a problem for you. Just be aware that it gets toasty when you're picking a spot/fixture for it. I was a little hesitant spending this chunk of money on a single light bulb but based on everything I've experienced so far, it's definitely worth it! Especially on sale ;)

The best one out there
Did my research on footcandles, luminosity, and all the other info that's out there about grow lights and this is definitely the one to get. You'll want it no more than 3ft away from the plants you're lighting, and no closer than 6". Very very good quality light. The color the light gives off is white, but not like hospital white so it's still a good vibe. My plants (and myself) are very happy!

Worth it!
Works like a charm! The light output is amazing and at a high enough par to actually grow plants. They get warm so dont touch the aluminum heats heatsink. Light color is perfect too!

Just a light
This does not work at all. I planted lots of different kinds of seeds 4 weeks ago. None of them are taller than 4 inches and most are shorter. I started using the grow light every day for several hours. 2 days after I planted mine at home I them planted seeds at a friend's house. Her's just sat in a window and those grew about 4 inches each week they are now 16 inches tall. She has no grow light just a window. This light is bright but it is not a grow light.

Does produce heat
This is a good light , it's very bright it's helped my rubber tree grow more leaves bc it's mainly on her but I did notice that I had the light very close and it dried out one of her leaves so try to have it about maybe 8inches away, the color is white

Lighter than the 36W, great results indoors
I’ve had excellent results with Sansi bulbs, and this 32W is no exception. My giant elephant ear plant is thriving since moving indoors under this light. Pros: • Not as heavy or bulky as the 36W version — easier to use in regular lamps. • Great color temperature, bright but comfortable in a living space. • Plants respond quickly with healthy growth. • Reliable Sansi build quality. Overall, a compact, powerful grow bulb that does the job perfectly.

A compact grow bulb with a Big Block V8 inside
Great bulb so far and gives off nearly the same power but at almost half the size as the 36 watt. The 36 watt is amazing as well and both are worth getting in my opinion depending on how many plants you are covering. Also by power I mean how much light the plant absorbs at a certain distance from the light. Being so small the power is nearly identical from a foot or two away. So it’s definitely punching above its weight class. 5 year replacement guarantee is also amazing.

Excellent
Excellent product. I had an issue with one of the products I ordered from them and the issue was resolved quickly after I contacted customer support. Will definitely purchase again.

Works beautifully
These work so well! I have orchids under them, tested the light output and they put enough out for my high light orchids. I have them in pendant light cords. Ive bought many grow lights on amazon and these guys are amazing for the cost comparison and light.

Seems promising
The light looks dull and yellow, but despite it seeming dark, the plant app I use still says it’s “med” light at the top of the plant. So I guess that’s good. Wish Sansi made 5,000K plant grow lights though because they really brighten up a space in winter.
