Easy "recessed" lighting look I bought the 12" Nickel model. It's good looking. Screws into standard ceiling light box, but looks and works like recessed lighting. Great for areas you don't have the ceiling depth for recessed lights, or just don't want to go through the hassle and expense of installing them. Works well on a dimmer. I replaced 13" flush mount celing lights with two 100 watt bulbs, and this LED fixture is brighter on only 17 watts. Because it's so thin it is more directional than bulbs that hang down. The light is more pointed towards the floor and does not spread around the room as well as other fixtures might. But that's exactly what you get with recessed lighting. I'm very happy with it, I bought 1 to try and I'm going to order several more for various other areas in the house. 5Very pretty This is such a nice, very flush, pretty fixture. It is very bright, so much so, we need to install a dimmer switch, but that's ok. It looks just like the picture. The company shot me an email to make sure all was ok, and also pointed me in the right direction for the LED dimmer. Seems like a great company! Very happy with this purchase and the customer service! 5EXCELLENT Light This LED light is very thin.....almost passes as recessed lighting. I have the 3K version, and the light is a more natural color than the glaring white light. Its easy to install, provided you are using a 3 1/2 inch screw to screw box. The mounting holes are 3 and a half center to center.......if you have anything else, you will have to modify. We have a fairly small dining area....and this light did the job......perfect for us. A great buy, and the quality is good. What would ;have made it great would have been a glass dome plate instead of plastic. Its on the ceiling, so who really notices.......it works for us. 5Inexpensive, and great looking I have a room with low (7') ceilings, and broke one of the existing globes that hangs down 9" or so. Rather than find a replacement globe, I decided to just replace the fixtures with these. Very easy to install, and looks great, plus we'll no longer hit the low-hanging lights with hands/heads. These are also much brighter than the old lights, which were incandescent, and limited to 100W.The (plastic) cover was a bit stubborn to remove for installation on one of the lights. 5This light is fanstastic! Wow, this light is just perfect. I had an old ceiling fixture in a hallway, the kind the hangs down and has a glass globe on it over a standard A19 bulb. I broke the globe while moving furniture and decided "that's it" and looked for something that does not hang down. I found this fixture. It has two wires that come out of it, plus a removable ground wire. I removed the ground wire - my house was built in the 50s and that ceiling box was not metal and there's no ground wire in it. I had to get an adapter from the smaller ceiling box to the 4" box (today's standard) fitting on the fixture but that was no big deal, either.The light took about five minutes to install. The hardest part was keeping the silicone ring "gasket" in place but I'm not even sure that was needed. The light is quite bright - brighter than the 60 watt bulb in the old fixture. I might add a dimmer switch.Now I have a light in that hallway that extends down only about one inch from the ceiling and looks good. I will not smash it ever again by moving furniture through the hall. 5LET THERE LIGHT! These LEDs are just what we needed to bring more light into our long, windowless hallway! Makes a WORLD of a difference! 5Edited Review; Great Looking Light - Easy to Install - Silicon Gasket might make you Crazy Edited Review - I sent an email to Hamilton Hills regarding the gasket and my review below. I was very pleased to receive a reply from HH apologizing for my frustration with the gasket. In the reply HH stated that they are currently updating the instructions to explain that the gasket is only needed when installing the light in a wet environment. HH didn't mention if they will include the secrets to keeping the gasket adhered to the light while installing it, but it's a big plus to me that they replied. Updated from 3 stars to 5.____________________________________________________________________________________________________________I just finished installing this lamp. It looks great and fills the room with plenty of bright light. The install was not difficult, all you need is a Phillips screwdriver and a ladder to reach the ceiling...however, and this is a big HOWEVER!The silicon gasket will make you crazy!! It will not stay attached to the fixture!! There aren't any instructions about the best way to install the gasket, in fact, the gasket isn't even mentioned in the supplied instructions. I read every review on Amazon and then searched the web for anything that might provide a clue to installing the gasket...nothing. There are multiple reviews on Amazon stating frustration with this gasket and no one has or is able to provide the trick so I just installed the light without the gasket and it looks fine. However, this does not sit well with my slight OCD when it comes to completing projects...I agree with the reviewer that said the gasket is better suited for ring toss.Note to Hamilton Hills - Why isn't the gasket mentioned in your instructions? Perhaps you should provide a better gasket, design or some clue to the trick of install. You get three stars because I like the light, but come on, really? 5These get VERY HOT in just a few minutes use! Taking them down don't want a FIRE! Purchased 3 of these for my Art Studio..Not sure WHY but the Nickel Ring is SO HOT I am afraid my walls will catch fire!!!Anyone Else notice how HOT the ring gets after a few minutes of use? I have to take these down and try something else!Install quick except for the stupid latex ring that is a NIGHTMARE to keep on! 2Cheap, bright, looks good, nicely put together, but has 60Hz flicker Short form: It looks nice, is inexpensive, installs easy, but unfortunately has 60Hz flicker.Long version: there are six things I look for when getting an LED light. This does okay on two, well on two, surprisingly fails the one that nothing fails anymore, and I can't say about the sixth.1) Efficiency. At 70lm/W this is middle of the road. I much prefer over 100, but it's cheap and about equivalent to a CFL, so narrow pass.2) CRI. 80 is decent, looks okay to my eye, so pass.3) For a fixture like this, how does it look? Quite nice, unobtrusive, and the light output with the diffuser attached is very even. Good job.4) Color temperature. Entirely a matter of preference, but looks pleasant enough at 4000K to me.5) Flicker. These days almost everything drives the LEDs with DC so there is none, but this surprisingly does not (with the diffuser off you can see the very simple circuitry), so it flickers at 60Hz. I hate 60Hz flicker, so wouldn't want this on any fixture I was going to use regularly. Might not bother others, but fail for me.6) Longevity. Impossible to say without using it, but on the plus side the circuitry is extremely simple so there doesn't appear to be much to break, and on the minus it also has no heatsink whatsoever on the board so it may lose brightness prematurely. Time will tell.Other comments: Includes everything you need to attach to a standard ceiling box (bracket, which I didn't use, screws, the light, the diffuser (the screws are hidden behind the diffuser), and a silicon gasket that goes between the light and the ceiling. My only complaint is that the gasket is really fiddly--it doesn't want to stay on the rim of the light and was a real pain when overhead to get it to stay there long enough to tighten the screws.On the plus side, because it's all surface-mount LEDs, this looks brighter than you'd expect from an 840lm light. If you put a similar-brightness LED (or CFL, or incandescent) bulb into a regular fixture, it's omnidirectional so a lot of the light is probably bouncing off the ceiling or inside of the fixture and being wasted. ALL of the light from this goes straight down, so all 840 lumens end up below the fixture.Installed it looks good, and since it's a rarely used fixture I'm willing to live with the 60Hz flicker. I'll update this review if it ever fails on me. 3It DOES Flicker! Also not very efficient for a LED. I purchased these lights specifically to replace equivalent lights in my home that have a 60Hz flicker. The flicker has annoyed me for some time now to the point where I no longer use the lights at all. I purchased these bulbs based on other reviews that said that these lights do not flicker, but I have found by recording them in slow motion that they do in fact flicker.Allow me to explain a bit further what this flicker is, what it's caused by, and why it bothers me but goes unnoticed by many people:An LED is a "light emitting diode" which means exactly what it sounds like; these devices are diodes that emit light. A diode allows current to flow in only one direction . The power in most households in North America and around the world is alternating current. Alternating current (AC), like the name suggests, alternates between positive and negative current flow (It flows in two directions ). Instead of having a positive and negative wire like direct current (DC) devices (think of a battery with a positive and negative terminal, batteries provide DC current), alternating current uses a "hot", or "live" wire, a neutral wire, and a ground (In DC applications the negative wire is usually also the ground). So essentially, the direction of current flow is alternating in AC applications.Now you know 2 things. The power in your home is alternating current, and LEDs allow current to flow in only one direction.Alternating current in North America has 60 phases per second, or operates at 60Hz frequency. Each "phase" lasts 1/60th of a second and consists of positive and negative half-phases, each lasting 1/120th of a second. Now look at the annotated diagram of an alternating current sine wave I uploaded. 1/2 of the time the voltage function is above zero (positive), and 1/2 of the time the function is below zero (negative).The individual LEDs on the circuit board of a light bulb can be oriented so that they are either on during the positive half phase, or on during the negative half phase, but each individual LED cannot be on during both phases in a simple LED circuit.Therefore, this LED light flickers at a rate of 60Hz.Now you may be thinking at me, "well, if you knew this, and the flicker bothers you, why would you ever buy a LED bulb?" which brings me to the next thing I would like to explain.Not all LED bulbs flicker!!!!!LED bulb manufacturers can include AC to DC converters in their LED bulbs to get rid of the 60Hz flicker. These circuits take the 60Hz 120V AC power supplied by your home's power and turn it into a DC power source. This is a function your phone charger provides for your phone. It provides your phone with 5V DC power to charge its internal battery. AC to DC converters are very common in LED bulbs, but one is not built into this bulb, which is why this bulb flickers. In summary, LED s which are powered by a DC power source do not flicker. If a LED bulb has an integrated AC to DC converter, it will not flicker (it also may take a second to turn on and may fade off when turned off).So, why might you not notice this flicker when I do?I don't know the exact answer to this because it does have a bit to do with psychology, and I m no expert on that (I m not an expert on anything, not even LED bulbs). With that said, I think it is due to a few factors. I think many people do, at first exposure, notice that the light from some LED bulbs is different than light from incandescent or fluorescent bulbs, but they might not care, they might dismiss it, or they might think their eyes are playing tricks on them. They accept that it seemed a little bit different, subconsciously think to themselves These are normal lights, look at everyone else acting normal, they don t notice anything so neither should I, and move on. I notice this because I am aware of it. When I was young, I had an interest in electronics, and I first noticed 60Hz flicker in old cathode ray tube (CRT) computer monitors and TVs. If you put your hand in front of an old CRT TV and move it around rapidly, instead of seeing your hand move in a blur, you will see sort of snapshots of your hand in different positions as you move it. This can also be noticed under the light of an LED that flickers, but it is a bit subtler in that situation. If you have never paid any attention to the flicker of any screen or any light bulb, you are not likely to notice it. Also, some people I have tried to demonstrate this to have trouble seeing it even when it is pointed out to them. If you were to put these lights above your kitchen sink and wash dishes every night, I would be surprised if you don't notice the flicker at some point in the first few months of use.With this said, let me describe how I observe a light flickering. I'm not super human, I can't stare at a light and tell you if it flickers. The minimum frequency for a human eye to detect flicker is 18Hz. However, that is for looking directly at a light source that is flickering. When motion is involved, things get a little bit different. Remember the screen example I mentioned earlier with old CRT TV's or monitors? I cannot stare at a CRT monitor or TV and tell you whether it is flickering, but if I put my hand out in front of it and move my hand around, then I can tell you if it s flickering. There are two ways I would recommend trying to observe whether lights flicker in the room you are in. One is to look at something on one side of a room, then quickly move your glance to the other side of the room and pay attention to your peripheral vision. If the light is flickering you will have seen the light in a few different spots in your vision, and if the light is not flickering you will have seen a streak of light as your eyes moved. Another way to tell is to move your hand, or a shiny object quickly under the light source without following it with your eyes. For example, I noticed that my current lights flicker while setting up my speakers for my TV. I had shiny gold-plated RCA cables in my hand, and when I moved my hand and the ends of the cables swung around, I noticed that instead of seeing a streak from the cable ends, I was seeing the ends in different spots in my vision.A definitive way to observe flickering lights is to use the slow motion effect on your smartphone. Check out the video above where I have recorded the light in 960fps with my phone. When the slow motion footage is playing back you can easily see that the light flickers. This will also work with 240fps.Here is a direct quote from this item s description at the time of my purchase: "50,000 hours rated lifetime. Instant on, no flicker, no UV, mercury free light. 15W, 950L, 120V." Notice specifically "no flicker". I have noticed that most LED bulbs that have "Instant on" also flicker.One more thing that I would like to point out about these LED bulbs is that they are 15W bulbs that emit 950 lumens (for the 2700k model). This is a relatively low efficiency of 63.33 lumens per watt. I am pointing this out because for a bulb that flickers, this is a low efficiency. Including a AC to DC conversion circuit in a LED bulb typically reduces efficiency, and these bulbs do not have AC to DC conversion circuits inside. As a reference, a Phillips brand LED I purchased in 2016, which has the exact same color temperature of 2700k and an AC to DC conversion circuit, emits 800 lumens using 9.5W, which is an efficiency of 84.21 lumens per watt. 1

I had shiny gold-plated RCA cables in my hand, and when I moved my hand and the ends of the cables swung around, I noticed that instead of seeing a streak from the cable ends, I was seeing the ends in different spots in my vision.A definitive way to observe flickering lights is to use the slow motion effect on your smartphone. Check out the video above where I have recorded the light in 960fps with my phone. When the slow motion footage is playing back you can easily see that the light flickers. This will also work with 240fps.Here is a direct quote from this item s description at the time of my purchase: "50,000 hours rated lifetime. Instant on, no flicker, no UV, mercury free light. 15W, 950L, 120V." Notice specifically "no flicker". I have noticed that most LED bulbs that have "Instant on" also flicker.One more thing that I would like to point out about these LED bulbs is that they are 15W bulbs that emit 950 lumens (for the 2700k model). This is a relatively low efficiency of 63.33 lumens per watt. I am pointing this out because for a bulb that flickers, this is a low efficiency. Including a AC to DC conversion circuit in a LED bulb typically reduces efficiency, and these bulbs do not have AC to DC conversion circuits inside. As a reference, a Phillips brand LED I purchased in 2016, which has the exact same color temperature of 2700k and an AC to DC conversion circuit, emits 800 lumens using 9.5W, which is an efficiency of 84.21 lumens per watt. 1
