SANSILED 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, 2-Pack

Excellent bright grow lights, don't get hot. I saw many reviews that they got hot, but for me, that is not true. They are in an ancient standing gooseneck lamp, and are super bright and simply warm to the touch. The seedlings are responding very well to these lights, and show deep green coloring and rapid growth. Very happy with my purchase.

Other than lying about being 150 watt equivalent, I’d say these bulbs are pretty good. Yes they are quite bright but all that light is focused in one direction. At 10 watts and 900 lumens they are not even 100 watt equivalent…Anyways they work great though and are cheap so five stars

I have a million house plants and have used many different plant lights, saw these on Sheffield Made Plants' YouTube channel. (Sorry if you see this and have a link; I watch on my TV.)Anyway, I didn't think that these would be any better than the ones that I have, but they are. The light is like a daylight white bulb, but super strong in all my plans love them. A lot. I have ones that are a warmer light because they're in my living room and some purple ones, but these have promoted way more and quicker growth. I have two in my bedroom for the vining plants above my bed and they've all taken off like crazy.

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.

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.

My indoor plants and seedlings are loving these lights. No noise or flickering issues. Heat has not been a problem and the size is perfect over my window seat fixtures. I’m hoping they last.

These bulbs are great! I got two boxes that each came with two bulbs. The Sansi brand is so great! These bulbs are wonderful for my plants and have provided full spectrum like I wanted so lots of coverage for a few plants in one spot together so that's really nice! I highly recommend @Sansi. They have great lights and your plants will thank you!

Energy efficiency is good, Lifespan I bet is good, Durability is good, Noise level is good, Functionality is good, Size is perfect . I bought these Sansi grow bulbs because I wanted to have extras just in case my other 2 burnt out. These bulbs works miracles I recently started growing strawberries seeds and these bulbs works 6 strawberry seeds are sprouting and my variegated umbrella tree has been putting out new leafs. I do recommend these sansi grow bulbs to anyone that wants to grow strawberries from seed. Thanks for the great deal on the grow bulbs.
