LED Grow Light Bulbs 4-Pack, 10W Full Spectrum, E26 Base, 4000K

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.

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!

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.

Great little grow bulbs. Don’t let the size full you. I’ve used these little lights for years now and they work great to get your seedlings to 6” before they need to hit the dirt. You don’t need a fancy operation to get your plants going.

A bit pricey, but effective for a small number of plants if needed. Probably better than a normal LED bulb, but not by an incredible number. Buy the higher wattage if you think you may need something stronger.

Great for the wattage and price. Definitely full spectrum. Got these pair on a deal to try them out. Absolutely love them and planning on getting their highest end and wattage bulbs for the next stage of growth. Definitely a great solution for those without deep pockets for high end LED grow lighting.

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.

Love these bulbs for my house plants, my plant babies are absolutely thriving under these bulbs! They work well in any lamp you happen to have laying around. I personally use these in our heat lamps I had laying around and in a flex clip lamp, they fit a basic light bulb socket. They do get extremely hot to the touch, I actually burnt myself on one by just barely touching it. I don’t make it a habit of messing with bulbs while they’re on so it’s really not an issue.

funcionanmuy bien, la luz es fuerte y si ayuda muchisimo a las plantas

My plants love them! Will especially be good come winter when light levels are low. Nice and bright, great price too!

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.

Good bulbs

These will heat up a grow box quickly and will burn you if you touch them while in use so be careful....aside from my clumsy moves, they are excellent bulbs and I will buy more in the future
