SANSI Grow Light for Indoor Plants, Clip-on LED Full Spectrum Plant Lamp with 4-Level Dimmer, Auto On/Off Timer (3/6/12 Hrs) - White, 10W 1-Pack

This light is great if your home don't have adequate lighting for your plants! I was skeptical at first, but this item did not disappoint. Long story short, I had my peace lily placed near an area not to far from the air-conditioning vent, and even though it was placed near a window, it wasn't adequate lighting. Because plant life is new to me, I had no idea what was going on until I asked the plant shop about it where I purchased it from. Once I moved it to a different area and directed the light on it, this is the difference that it made in just 9 days. SN: I used the setting for 12 hours and it's on the fourth brightness setting.

I am a plant lover, but my house/windows and the sun don't mix well. With the purchase of this light (I now have 3 of them), I am able to grow as many plants as I want! Thanks for helping me become a plant mom!

Bought for a work colleague. She has a succulent and is now able to keep her plant in her office (there are no windows in her office). Her plant has been growing a lot faster now than when she had it in the common area window.

As a lunatic with 700+ houseplants, I think I’ve tried just about every grow light Amazon offers. This upgraded clip-on from Sansi is definitely my favorite. The light is strong and my plants instantly responded. The size is unobtrusive and easy to position so that you don’t blind the other people in your home. If the strength of the twisty stem part could be improved, I would toss all the competitors.

Hey yall,I wanted to modify these excellent lights to work with my grow light timer and in the process i discovered how horribly inefficient the power adapters on these light are. i also figured id share some measurements i made with my light meter to help any one who doesn't own one figure out how much light they are providing to their plants. Last i used the data i collected and crunched some number to check sansi claims regarding light intensity.Anyways, I posted a picture of the timer/dimmer/switch for any one who would be interested in modifying these to be "Always on". Few people complained that these are not compatible with any timer you may have for existing grow lights. I ran into the same issue. The solution here is obvious. You basically have to bypass the board. I don't recommend you do it if you don't know how to do it right. But if sansi is listening it would be nice if you can add another set of barrel connectors above the controller. This can not only allow people to bypass it but also adjust cord length and controller positioning. I have almost knocked down other plants attempting to turn on my lights. I can't be the only one with this problem.While i had this disassembled I decided to measure exactly how much power these lights are using. i saw one review that stated that he used a kill-a-watt meter and saw a output of 10w. I used a multimeter that i tested before and after the readings. At the highest brightness settings i measured 16W at the wall. So then i took a reading after the adapter and got a reading of 6.3W. I found this alarming. That would mean that the power adapter on this grow light is only ~40% efficient at converting AC to DC. This is insanity. i repeated these measurements for every power setting and repeated some with other adapters that came with the five other Sansi grow lights i have with similar results.Let me put this into dollars and cents. I use theses grow lights for 16 hrs a day and a kilowatt hour here in NYC after all charges is about $.31. One year of operating this this light with this adapter will cost me ~$29. If Sansi provided Gallium Nitride (GaN) adapters which operate at a efficiency of ~90% it will cost ~$12 to operate for a year. For me with my three lights will be a difference of ~$51 a year. Im lucky that i have the know how to make this happen safely. I do not know how poor the quality of adapters are provided by competitors. This may not be a fair comparison for Sansi. But if i had any recommendation for Sansi it would be to get more efficient power adapters!(For reference a 12v 30W GaN adapter cost about ~$18 retail and should be sufficient for my three lights)The last thing i wanted to share was another small spread sheet i made. I used 6", 9", 12". I figured this would be useful since on their website they make recommendations on how far you should place the lamps to certain plants and what the coverage would be. And yes its a sharp exponential drop which then had me thinking.....Using that data i can calculate if sansi is being honest on the amount of lumens their light produces. Lumens and Lux are related to each other 1000 Lumen source will produce a 1000Lux at 1m if it had a beam width of 1M^2. When i measured the amount of light i got at 1 meter i got 499. I chuckled. In their marketing material they claim a beam width of 1.07 ft^2 and 1.94ft^2 at 9" and 12" respectively. If you extrapolate they claim that at 1M you will have a 2M^2 beam width. I didn't attempt to measure the beam width my self but the math worked out perfectly. (It didn't line up when it came to the amount of lumens i got at 9"&12" ~395Lux @ 39.72"(1m) but it think this could be because of a not perfectly uniform beam)Moving on. I like the grow lights. They work as expected they look nice and my jalapenos and strawberries are doing great!

Prefect Lego’s lights. Cord length was good, doesn’t give off heat very good item

These are amazing. We use them to support plants in our windowless bathroom. It works so well the plants are getting too large for the space. Impressive

This light is MARVELOUS!! I've got 2 of the 5 light sets, but needed just single one for a low light plant. I love the adjustable brightness on this. It is absolutely perfect
