SANSI LED Grow Light Bulb for Seeds and Greens, Full Spectrum 10W Grow Light (150 Watt Equiv) with Optical Lens for Indoor Plant, High PPFD, E26 Base, 4-Pack

I have a number of Sandi LED grow lights that I have used for years and that have never failed to work. I decided to order these bulbs so I could use them in a different lamp. From my experience with Sansi LED grow light bulbs, they last for a very long time. They usually, 99.9% of the time do not have any flickering, and when they do flicker, I just turn it off for a while and turn it back on after the light cooled down. As I said, they flicker hardly ever. We have these I the living room window. I would have noticed, if they flickered often. They are on every day or many hours, they have not failed. The light quality is excellent. I have noticed increase growth in my plant, increased blooming, and increased root growths, which is a sign of a grow light that meets the plants’ spectrum requirements. The bulbs simply get screwed into the sockets like any other light bulbs. I love these and will by more, should the need arise.

I'm using these for some built-in overhead lighting for an aquarium, with a in-wall light switch timer. First, these lights will not work with a dimmer. I don't mean they won't dim (they won't, of course) but they refused to work even with a dimmer set to full power. I know this because originally my light fixture had a dimmer, and I was waiting for the timer to arrive in the mail, so I thought I'd just plug these bulbs in and manually turn the lights on, just leaving the dimmer on full. However, they spazzed out when I tried, so I had to wait until the timer arrived/install it in order to use them. Second, they don't seem to get nearly as hot as some others claimed. I believe the instructions indicated that they are not to be used in an enclosed light fixture, so maybe they would get much hotter in that sort of situation. If they really consume only 10W (which I haven't tested yet), then they literally cannot produce more than 10W in heat, whereas 60W incandescents put out something like 50W into heat. I'm definitely not complaining about their heat output. Their light is in a fairly narrow beam. I think the listing said 30 degrees or so. I had to raise my hanging light fixtures significantly to get good coverage on my aquarium. I would have preferred a slightly wider angle, but that's just personal preference. It's not really a flaw. The bulbs are pretty small, so they fit in a small fixture. They are a bit smaller than a typical incandescent ~60W bulb. They are pretty bright. I haven't measured the brightness, but they are mostly sufficient for my aquarium. I say mostly, because my aquarium has a lot of floating plants, which block a lot of light for the lower, submerged plants. I ended up buying the slightly brighter but very similar 15W/"200W Equivalent" Sansi bulbs, and I will probably use these 10W bulbs for some other project later. I also can't really speak to the light spectrum that they output. Most aquarium plants aren't super picky, but I'm also growing some emersed plants riparium-style and they are a bit pickier. Time will tell if they like the light that these output. However, just eyeballing it, they look pretty good. I also definitely cannot speak to longevity yet. Mine are on about 8hr a day, switched using an automatic timer, so not a lot of on/off wear (which seems to stress the cheap power supplies found in most LED bulbs), but a lot of "on" hours are added daily. I'll report back if and when they might break.

These work perfect in the lamps I got. Not too bright for the area but definitely bright for direct beam within 4ft of a plant. Only had them up for about a week so can't say as to the quality of light or durability or how the plants like them but the plants look great under these bulbs and the color is cozy and bright but not white and sterile office feeling. To me it feels slightly whiter light than sun light. No sound that I have noticed from them. I would say the plant at the farthest side from the light is about 12ft and feels like bright indirect light or just under than. So may need a brighter one for my space.

I have purchased these bulbs in the past. The light is not too bright but a perfect brightness for my living room and to help my indoor plants grow. The bulbs seem very well made but I find they don't last as long as LED's should. I would say about every year I have to replace it. The light stays on all day long and is only turned off at night so I do get a lot of use out of them. Considering how old fashion bulbs lasted, I am guessing this isn't too bad. I like getting the 2pk so I always have an extra one laying around if needed. My plants appreciate it and it gives a nice light in the living room. Overall I am pleased with these bulbs.

Amazing grow lights that really work!!! Your plants will love you!!

Perfect wattage of bulb for enough lighting but not overwhelming for plants. Only drawback is the heat from the bulb.

Great bulbs. Keep my plants alive

Came well packed, with excellent protection. Was surprised how heavy they are, heat sink must be quite massive. Came on instantly, put out a lot of light for 10w. Color does look like natural light, with no flickering. Light is well focused in the 60 degree spread, appears very evenly distributed. They stay cool in operation, which should be good for longevity. I'm well satisfied and recommend them.
