NorbSMILE Full Spectrum Sun Light Bulb - CA California Energy Compliant, Par 30 Long Neck, 10W LED Flood Style Light Bulb, Natural Sunlike Spectrum Imitates Sunlight Indoors, Patented (1-Pack)

a very bright bulb, non dimmable though

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.

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. :)

So, I had to give this 4 stars, because it IS everything they advertise it to be. It works well. It is made well.It all comes down to what type of light and atmosphere you feel happiest with in a room. For me, these were too stark white and cold looking. Thus, the loss of one star.I like things bright and sunny during the day and warm and cozy at night. My problem is night just comes too quickly in the winter. If you keep these on during the day, especially on a cloudy day, they will give you a sense of day time inside. It is a very white (with a little blue) stark light, but not as apparent during the day. They were way too cold looking for me at night though, when it finally should be night time and you just want your nice warm cozy space. I don't want it to still be looking like daytime at 9:00 at night. I also don't want to be switching out bulbs 2 times a day.My husband feels that traditional soft white light bulbs are just too yellow at night and harder to see by. Soooo, I think I found a compromise. I purchased four 4,000K 60 watt LED light bulbs. Yes, we have four lamps in our living room. So far, they are a good compromise. They are not stark white, nor are they annoyingly yellow (to satisfy my husband), yet they still seem to satisfy my need for warmer and cozier. Definitely not stark and cold. A little dim, so I may go to a 75 watt bulb. All of these led type bulbs seem much dimmer than regular standard 60 watt, soft white, light bulbs. If I only had one lamp in my living room, this would be a problem and I guess I would be purchasing higher wattages.If you suffer terribly from SAD in the winter and you want it to look like daylight all day long, then these are the bulbs for you! Put them everywhere. Just know, it won't look like the sunshine from a bright sunny cheerie day. It will look more like the bright white light you see when you go outside on a cloudy day, when the clouds block the yellowness of the sun and makes for a very white daylight. Again, all subjective, but those kind of days depress me. (I need the bright yellow sunshine of the sun.) So, I wouldn't want to emulate that look in my home.This review is for the person who may be like me. The kind of person who dislikes a room with no windows and only fluorescent lighting (pretty awful 😞). It may be ultra bright, but for me brightness does not equal the feeling of a warm, bright, sunshiny, summer day. I'd rather paint all my walls a soft pale pastel yellow, which I did, and then create a happy cheerful lighting to create the look of a sunny day and trick the mind. After all, that's what I'm missing most of on those shorter, often cloudy, winter days, with nothing but white light.One caveat, I may use one of these bulbs next to my bed, on a timer, to help me wake up in the morning when the sun rises all too late. Hard to get up and running in the dark. These may be just the dose of bright light I need to jolt out of bed.Again, this light is exactly as advertised, just buy based on the type of lighting and atmosphere you want to create and use where it can best suit your needs.

This light really seems to keep my animals happier and gives them a much better attitude versus regular lights. Highly recommend

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?

Rated that if “Used 4 hrs per day, the LED is expected to last 12 years.” Purchased 3 years ago, not opened for a while afterward, used only occasionally, and function appears satisfactory, BUT just stopped working. Does not appear to be meeting standards. Can anything be done?

No sientes ninguna vitalidad ni que sea como parecido a la luz solar o que te dé algún estilo de sensación diferente nada carísimo solamente
