NorbSMILE Full Spectrum Light Bulb - Sunlike Premium A19 9W Wellness LED. Boosts Energy & Mood, Supports Circadian Rhythm, High Color Rendering, Imitates Sunlight Indoors, Energy Compliant (1-Pack)

This was a buy again purchase we had originally done in 2019 for our 86 year aunt. She likes these bulbs in the lamp next to her recliner in front of her TV. She feels it keeps her feeling happy.

Great lighting effect

Great product

This bulb has an excellent CRI/Ra of 98.1 and the blue part of the spectrum is nice and broad without the typical blue spike. The red part of the spectrum is lacking. I was hoping the spectrum would be close to the one advertised in the product description. It was rich in red and near infrared but the actual product’s spectrum is different.Measured on a Sekonic C-7000

I was a little skeptical, but thought it might make some improvement so I'd try them. I bought all 3 types - SMILE, FOCUS, SLEEP. Huge difference immediately. There was a haze before using normal LED bulbs (from a brand that has been making bulbs for decades). Right away the room appeared crisp and clear using the same wattage SMILE. I don't know that I would have believed the difference if someone had told me without me seeing it for myself. (So jaded from marketing, and phony reviews.) SLEEP really helps me. The first night - no lie - I slept 11 hours straight. I felt so refreshed when I woke up. Since then, I get a normal 6-9 hours a night, but I wake up feeling more clearheaded. As for FOCUS, I have only used it a few times at my desk, but I do see clearer. It's an expensive set of bulbs, but I'm saving money by not needing Tylenol as much. :)

Got 2 - worked okay for a couple of weeks, nice bright light, then one started flickering; it progressively got worse and then the 2nd one joined in only a few weeks after. We now have the "benefit" of "light-shows" happening randomly. No other lights in the house are flickering while this happens.UPDATE: one started turning off and back on a few days ago, the switching frequency increased soon after, then it turned off completely. Switching the lights off and giving it 30 min can allow it to restart but hen it does it again. The second bulb now started flickering more often. I replaced both with some standard daylight LED bulbs. Where I live now I can't even throw them in the garbage, have to take to take them to electronics disposal center.In conclusion, it looks like poor QC, bulbs expected life time around 200-300 hours, you could have one working for a while if used 20 min each morning, to "Supports Circadian Rhythm". The bulbs are above the kitchen island, with wide shades, so it is not a problem of overheating.Can't comment on "Full-Spectrum Sunlike” other than at such poor quality who's to say you get any other claims about the product.Also, got an automated email response to my initial 1 star review, I assume this is a built in function from Amazon, seen the same text from other sellers before. I find it useless and quite offensive.For starters, even if I get money back or free replacements it doesn't change the poor quality of the product, so my review stays (or is this why the good ratings on Amazon?). Then, how bad is your product if you need an automatic system to handle customer complains?

I've been using these for a few years, and I'm at the point where I am not going to buy them any more. I use two of these in my home office, in the ceiling light. (I had new electrical wiring in the house done Oct 2021, so it's not that.) They just don't last. I have to replace them in about 7-9 months. I use them for about 14 hours a day, roughly 5 days a week. I have other LED lights on my porch that I've had for over 4 years, and they run about 13 hours a day x 365 days of the year. I have no idea why these don't last.

Good product. Too expensive. But the effect of the light is appreciated.
