SANSI LED Grow Light Bulbs 4-Pack, 10W Full Spectrum, E26 Base, 4000K | 150 Watt Equivalent, Optical Lens for High PPFD, 4000K Natural Daylight, Par20 Grow Bulbs For Indoor Growing Seed Starting

The best quality lights is Sansi, LED, grow lights. They just are, for the price, and come in a package of two, for the price of one just about. Id recommend these bulbs to anyone trying to start an indoor growing project with a big plant, small plant, or small plant grows into big plant. These light bulbs are very resistant to fall damage, believe me I've dropped a few. All day light, with added heat produced off its emitted glow, and will last for years, comes with a lifetime replacement warranty too.

Best grow bulbs I've used. The light looks clean and natural—no weird purple tint—so it blends perfectly into standard living spaces.The Results: Noticed a massive explosion of new growth in just a couple of weeks. Even my finicky tropicals are thriving.The Build: Fits standard fixtures perfectly and runs nice and cool, so there's no risk of scorching delicate leaves.10/10, will definitely be ordering another pack to convert the rest of my lamps!

I bought two sets of these several months ago. I waited to write a review because I wanted to see how much difference they made to my electric bill and they made 0 difference. I run them (4) plus several other type grow lights 12 hours a day and these have made no difference in my electric bill and my plants are flourishing. I would recommend these 100% I will be buy more as my plant collection increases. They have a long lifespan they are a great value for the money. No flickering

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.

It’s pretty good. Cheap and bright. It works pretty well, as you can see in the picture. I’m growing butternut squash and rice

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.

Perfect for my plants.

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 plants in a super shady room in my house and these lights have done wonders in a few weeks. My plants are happier and thriving. I have purchased two more times from sansi and will do so again! Great price for a great product

Wow what a difference I noticed in the darker days last winter. The plants grew steadily and lots of success with my cuttings too. Very reliable, fit standard lamp socket which is very convenientThe light is white but not too white that makes you feel you're in some laboratory somewhere!

Very bright light for the plants, they loved it and grew very quickly with it. Not so comfortable for the eyes, so make sure not to look directly into the light.

Magnificas luces, yo las empleo para orquídeas Dracula y van espectacular. Tienen nuevos brotes, y las plantas literal se levantaron. Solo considerar tener una distancia mínima de 40 cm del foco, si no se pueden quemar. Ya que se calienta el foco con cerámica. Excelente producto.

Good bulbs
