SANSI Grow Light Bulb with Ceramic Technology, PPF 27.2 umol/s LED Full Spectrum 15W Grow Lamp (200 Watts Equiv) with Frosted Optical Lens for High PPFD, Energy Saving Plant Light for Fruits & Flowers

These are "good enough" grow lights. I use them for my aquarium. I originally got the 10W version but it was not quite bright enough, so I got these 15W ones and they are a little bit brighter. Maybe my eyes just aren't skilled at seeing the 50% higher output. Don't humans see light intensity logarithmically or something? Anyway...The lights are pretty good and relatively cheap. They don't actually get very hot (15W radiated from a bulb-sized object is almost nothing). So far my emersed, immersed and floating plants all seem to like the light that they give off. Like with the 10W, my only wish is that the beam angle would be a bit wider. I had to raise the light fixtures to get them to have good coverage on the aquarium with their ~30deg angle.Honestly, I doubt these are amazing lights, even for the price. Just pretty good, and some of the better value on Amazon from what I've seen. They will not grow most plants as well as a bigger/wider grow light fixture would, but for a basic E26 bulb that can fit in fairly tight fixtures, they are sufficient.

I brought my plants in for winter and most ended up in the bathroom. After a few weeks I saw they were struggling and decided to buy these bulbs and I am so glad I did! After a month of using them I noticed tons of new growth and leaves are much bigger as well. Definitely recommend picking some up if you’re considering it

I don’t have a lot of good windows in my house and my monstera was getting big and starting to grow crooked reaching towards the light. So I moved her and got her this light, and she’s so happy now! The light is super strong and I can tell it’s working bc the newer leaves look so nice! Overall, i’m very very happy with Sansi lights! They’re worth it for sure!

Initial review is about the Seller and/or Amazon delivering fragile grow light bulbs in an envelope without any other padding. Watch my video!I'm so so surprised that the light bulb arrived intact and works after looking at the delivery envelope and original box housing of the bulb. I haven't had the grow light long enough to speak on longevity and functionality so I will update my review at that time. For now, I'm extremely disappointed at how this fragile grow light was delivered to me.

I used to love these grow lights and own a ton of them. Recently, they changed the design and the new bulbs don’t put out nearly as much light!I’m a nerd and measure my grow lights with a lux meter. The old lights (pictured right) consistently put out 2000 foot candles of light. The new design (pictured left) is putting out a max of 1000 foot candles. One of the new bulbs I received even puts out only 200 foot candles, one tenth the old output!!These new bulbs are being advertised as the same wattage and ppfd as the old lights, which is clearly false advertising. I’ll be looking for a new grow light brand.
