Great item!
I love sansi products. It’s not dimmable in the traditional sense, you chose 25% 50% 75% 100% brightness. No buzz like other brands and fits most light fixtures

So far it Is working well
I must say in advance that these bulbs should never be used in a closed shade. These lamps get very hot. If you want your shade to look cute, then get something like wicker, rattan, or rod with open spaces. I had a 36w bulb with a rattan and white cloth shade. I could not touch the bulb and felt heat coming off of it. Once I removed the white cloth shade, it still looked cute with the rattan shade and there was no heat. I read some of the reviews with several people having issues with the remote. I have had it a couple of days and the plants are loving it. I ordered a floor lamp I am waiting for, but I was able to screw it into a ceiling fan light fixture with an extension for now and the plants are drinking up this light. I love the remote feature that is working well so far. I am considering purchasing another for a hanging grow lamp. What is nice is you can use these bulbs in any regular lamp so long as the socket on both are compatible.

Really nice looking light, and effective and High PPDF output.
This is actually a very good light. The PPFD is strong - I measured it. It does get hot, so be careful. After trying several brands, I think the two leading options for houseplant grow lights are Sansi and Barrina. Both are full spectrum, but the quality of light from Sansi seems better, it looks and feels nicer than Barrina’s. My only gripe is the form factor. Almost everything Sansi makes is a bulb or a spotlight-style design that points directly at the plant. I’d love to see them make T5 or T8 fixtures that can line a shelf like Barrina’s. They do have one, but it’s way too expensive for just a single 2-foot light. Maybe Sansi will read this and take the hint.

Helps my plants grow!
I have large tropical plants that spent the summer outside and need adequate light to not go into shock when they come inside for the winter. I love this bulb, it has a remote for the timer and the light candles are SO HIGH! I don’t hear any noise while they are on, and they’re priced well. I was able to get them on anytime deal and that was awesome. They are functional, the timer allows me to set it and forget it basically. I’m not sure if the lifespan just yet as I’ve had it for about a month. I liked the pendant light set up to fit with my home aesthetic. It hasn’t overheated this pendant at all, nor has it burned any leaves. Totally recommend.

Heavy bulb
It's a great bulb, on the heavy side and it does get warm.

Pricey, but a pretty slick piece of gear
Fifty buck is a lot for a light bulb. But this does a whole lot more. The smarts in the base, combined with the handiness of the remote, makes this device very easy to use.

The only bulb to get
An actual grow light that helps your plants grow. My monstera is thriving! Knockoffs are glorified light bulbs that don’t actually have full spectrum light or the intensity is too low.

Happy Plants
Just love my Sansi lights, I don’t have to worry about my plants getting enough light while inside the house for the winter. Bonus is I started purchasing the automatic lights and now it’s one less task I have to do.

Nice powerful grow light bulb that can be used with a regular lamp. The round bulb design is good for giving a lot of light and warmth in a relatively small area, like a small shelf. The timer is pretty precise. Note that the bulb does get warm and creates warmth for the plants under its light, but it's not hot enough to hurt if you touch it. So you need to pick plants that like warmth to use that light. If you prefer cooler light and/or something that covers a wider area, I would recommend using a tube-shaped grow light.

I have to say how impressed I am with this seller and the grow bulb. First, the bulb is excellent quality and works very effectively, and second, when I noticed a recent price drop on this bulb 2 weeks after I purchased it for a higher price, I reached out to the seller and they refunded me the difference with ease and expediency. I couldn’t be happier with this transaction and I will definitely buy more bulbs from them in the future!

SANSI Dimmable Grow Light Bulb provides beautiful lighting but I find it too heavy for my equipment.
