Low profile and clean looking, doesn't dim as well with LEDS
934147
Summary: Works well but takes a little getting used to, and the dimmest setting with LEDs isn't perhaps as dim as we'd like

It takes a few weeks to get used to pushing a button instead of flicking a switch, but we like the cleaner, low profile look.

We have this on a fixture which has all-LED bulbs and we found that it doesn't go as dim as it does with incandescents.  We've found this with other dimmers - I guess the LED bulbs dim differently.  Bummer.

Perhaps in hindsight, if it wasn't for the killer price, I would have gone for the<a data-hook="product-link-linked" class="a-link-normal" href="/Lutron-TG-603PGH-WH-Toggler-eco-dim-600-Watt-Dimmer/dp/B001F6RGKU/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Lutron TG-603PGH-WH Toggler eco-dim 600-Watt Dimmer</a>&nbsp;More conventional switch with a more LED compatible dimming.

I little on the dim side compared with some of the single LED versions.
Don't think there's any real advantage to having 3 LEDs.
It is fairly light though...

I purchased this style (as well as&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/its-half-receptacle-brother/dp/B001H1JJK8/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">its half-receptacle brother</a>) to use for interior stair lights.

This full-height version uses 3 "off the shelf" LEDs (we're not talking super bright Cree diodes here), and in fact put out a bunch of usable light in dark and dimly lit areas. On the stairs in question, I played around with alternative spacing, and managed to get adequate coverage of 6 stairs when mounted at an outlet height of about 16" (covering two steps up, and three steps down from the stair tread the light was mounted over).

Compare this to the single-LED, half-receptacle version I linked to in the above, which truly works best in the complete darkness, and got me about 5 threads worth of coverage (two up, two down).

The problem I had with both of these was aesthetics: Neither is shrouded, so both stand out quite plainly. But this three-LED version is especially eye catching (in a bad way) when it's up the staircase closer to eye level. So my stair lighting idea went out the window.

However, what I found was that this version of the light is perfectly suited for bathroom and kitchen ceiling-mounted night lighting. In fact, the fixture is nearly invisible mounted in a single-gang electrical box in the ceiling (nobody ever looks up) and reliably cuts off whenever normal lighting is on. Perfect for midnight potty and/or snack runs.

And while I haven't attempted this myself, it appears very easy to open the lens and snip one of the LEDs, should a lesser light output be desired.

And we've elected to keep the half-receptacle versions as "pathway" lights down at floor level. They're very well suited for this task, providing just enough light plus outlet functionality, where we found this 3-LED version a bit too bright.

Nice look and quality... would be nice if the lens was a bit more obscure to completely hide the diodes from the LED's

I thought this light would be a good low profile light/fan for my lower ceilings, compared to the current fan that was there, but it actually sits a little lower than the old one!  The base is actually much larger than it looks in the photo, so go by the measurements only on deciding if it's right for your room.  The two lights are very dim, so we purchased 50W bulbs, which improved it slightly, but it's still pretty dim.  At least it's in a bedroom, and I can put a small table lamp next to the bed for more illumination when reading.  It's super quiet and moves air well, which is wonderful!!!!

I replaced a stairwell wall sconce with this product.  I was looking for something modern, LED, finished in brushed nickel, that would work effectively on a neutral wire dimmer.

Construction:
The light fixture consists of the glass, two end pieces, the facia plate, the back assembly, and a utility box adapter plate (optional, depending on your mounting scenario).  The facia and back assembly have decent (but not exceptional) finish quality, and the metalwork is devoid of visible seams.  There's a power transformer included.

Pros:
The light is attractive, and the assembly is relatively straightforward.  The light does work with a neutral wire dimmer.

Cons:
Since I was replacing an existing light fixture, I used the included utility box adapter hardware.  I don't think it would be as noticeable if I had mounted my light horizontally, but the adapter hardware does detract from the overall look somewhat.  The screws for securing the metal tube endpieces are a little tricky (especially vertically).  The transformer is not exactly small, but must be put into the utility box, as there's nowhere else for it to go.  Dimming is fine down to about 15-20%, and then the flickering starts.

I needed to light a kitchen sink and adjacent counter areas where there were no cabinets above.  I installed this set of fixtures in a row attached to the soffit above the area.  The result was entirely satisfactory, especially with the dimmer control to permit fine adjustment of the amount of light at different times of day and night.

If you anticipate a similar installation, be aware that the screws that come with the fixtures aren't appropriate, as they are designed to mount to wood cabinets.  I used #6x3/4" flat-head screws and matching drywall anchors, which fit the two mounting holes on each fixture perfectly.  I also purchased three of the 4" interconnect cords to chain the fixtures together.

Also, the cord from the dimmer to the (first) fixture is less than 4 feet long, which was too short for my installation.  Lightkiwi doesn't appear to offer an "extension cord" (male connector on one end, female on the other).  Instead, I cut the connectors off the end of the dimmer cord and off one of the unused longer interconnect cords that came with the fixtures, then spliced them together.  I put the cord from dimmer to fixture inside a surface-run wiremold so that the splice would be hidden.

Overall, these fixtures were a cost-effective way to provide more light over the sink and adjacent areas, and the job was much less work than installing line-voltage fixtures in the soffit, which would have been the alternative.  I'm happy with the quality of the product and the final appearance.

I specifically wanted these for the low-light-output.  They have a nice low-spectrum shade and don't glare on the eyes if you look right at them.  Great for 'exposed bulb' fixtures that don't have frosted covers and such.
If you're looking for the brightest light for the lowest wattage, these are Not the ones to buy.  If you want mellow mood lighting with no glare, these could be the ones.
Check the lumen count of your current bulb to get an idea. These are an 80 lumen count bulb, so pretty low.

Got these for hanging under the kitchen cabinets, above the counter tops.
Pros:
-Positioning is easy. The clips are cheap, but they get the job done.
-Whole thing is pretty low profile, which let's you house it fairly well in most cases.
-There's a little inline switch on the power cable that's about the right size to stick inside some trim for easy, hidden access.
Cons:
-Only projects light across ~45deg. Good enough for most scenarios, but can require some finagling to get the edges of the light positioned correctly.
-Light isn't consistently "white." On the edges of the light coverage, there is a strip of yellow. It's the kind of thing that a passer-by wouldn't probably notice, but once you see it, you'll never not notice.

simple unit, and smaller than any other I have found so it looks better. The light color is pleasing, and the ability to rotate the strip inside the two clamps is a real plus, All other light strips I have found are fixed to point down, but in my install under a low hanging bathroom medicine cabinet I found that the light was most pleasing if I rotated the strip to shine on the wall and underside of the cabinet and use the reflected light to create a nice complementary soft fill light.

Yes, I am going to buy more, they are cheaper AND better than any I can find anywhere else.

I purchased this fixture to replace an existing LED retrofit downlight fixture at the top of a staircase which also happens to be the only light for it, I wanted something with a narrow beam that could be pointed toward the steps and this worked beautifully. This light has a narrower 36-degree beam that throws a pleasant light and only uses about 10 watts. Installation was very easy as with most retrofits of this kind. The light was a little brighter than I cared for so I purchased a Lutron dimmer TGCL-153PH as it was one of the models the vendor listed, I am very happy with this combination of light and dimmer, it goes from about the equivalent of a night-light all the way to its maximum and the system is silent. Note that this dimmer has a small (under 1-second) delay before the light turns on,

Pretty nice little keyboard.  I am fond of the the low-profile keys as they tend to be more quiet and are easier to type on.  My only wish is that the lights were brighter!  But still, looks cool.

I wanted a lamp that is low-profile and also has a good amount of reach between the base and the lamp head, so I can put the base near the perimiter while having the light source above the center of my fairly large desk.

The Z-Bar has worked out well. I'm using the clamp-on base, which doesn't take up any desk space. However, the included round base is flat (it's about 3/8" thick), so it wouldn't really reduce desk space either, since papers can be laid on top of it. The lamp is well made and doesn't feel flimsy at all (as one might think from the photos and the general design). It's about as low profile as possible. It puts out a lot of light and the light quality is excellent. I got the "daylight" version and the light isn't blueish at all. The light is similar to that output by "full spectrum" cf bulbs. It's also nice not to have the heat of the halogen lamp that I was using previously.

My one suggestion would be to place the on/off/dimmer switches on the light bar, rather than at the base of the lamp. My lamp is mounted at the rear edge of my desk and it's a hassle to have to stand up and reach back there to adjust or turn the lamp on or off. A second issue is that while the light directly under the leds is nice and white, light towards the edges of the illuminated area has a yellow hue (due to refraction issues from using 6 leds spaced apart). Not a huge deal, but it does detract from an otherwise great lamp. If these two issues were resolved, I'd have given it 5 stars instead of 4. The "six shadow" issue mentioned in other reviews doesn't bother me.

I was initially hesitant to spend this much on a desk lamp, but after looking at the alternatives with similar features, this is actually reasonably priced. It won't need replacement bulbs for years and uses less energy than halogen. I also justified the purchase by telling myself that improving my workspace will make me more productive. Looking at it this way, the lamp will pay for itself!

Lets hope it holds up over time. Another led lamp I own (not made by Koncept) has developed an intermittent contact somewhere in the circuitry over time, which results in flickering and having to fiddle with it to keep it lit. There are a few comments here describing a similar problem developing with the Z-Bar. Hopefully these are the exception.

Update:
I've been using this lamp daily for over 4 years and it's worked flawlessly. Not a single problem. In light of this, I raised my review from 4 to 5 stars. I'm now looking for another "extendable" lamp for my bedroom and might actually get another one of these, since I haven't seen anything else with as much reach.

I put these in my dining room chandelier as an energy saving upgrade.  It was hard to find attractive, dimmable candelabra base bulbs so these were ideal.  One thing worth mentioning, if you are using an illuminated dimmer switch there's an interesting side effect.  The bulbs do not go completely dark when shut off.  The trickle current used to illuminate the dimmer switch is strong enough to light up these LED bulbs.  It's not using any more power than it did before (less, actually).  It's just that LED bulbs take a lot less current to light than incandescents.  When it's fully dark the bulbs are lit about as bright as candles.  The solution is to buy a non-illuminated dimmer control.  Unfortunately not all dimmers mention whether they are lighted.  I bought a replacement for $25 and it turned out to be illuminated as well.

I like the quality of light (pure white) and volume of light it produces. I also like the low profile structure, which I think will be less likely for me to bang into it when moving bulky/awkward items in my shop. It was also very easy to hook up - just strip the 14 gauge Romex insulation (not included) and slip each wire into the attachment, where it locks easily into place.

Good product, plenty of light, but a cold white as LEDs are (i.e., not as warm as an incandescent bulb).  I needed a low profile fixture and this fit the bill.

I'm using this dimmer to control around 10 feet of LED strips on a shelf I built for my figure collection. Most other cheap dimmers I saw were listed as 8A, but customer reviews indicated they were really only 0.8A, which was definitely a no-go for the 5A my lights draw, so I went heavier duty. Plus, the Torchstar unit just looks a lot better than those cheap beige plastic ones that everybody and their brother sells.

There is a certain amount of whine from the dimmer when it's not full on or full off. It's most noticeable at a certain point just above 50%, otherwise I pretty much have to listen for it to notice it. That's something to consider though if you're installing it in a quiet room or are especially sensitive to very high frequency sounds, and is the only reason I'm knocking a star off an otherwise good little device.

I just noticed that another reviewer mentioned that it doesn't include mounting hardware, but that honestly never even crossed my mind. Living in a very DIY-oriented household, we had screws sitting around that were perfect for mounting it, so it never bothered me, but yeah; be warned that there's no mounting hardware included.

Fun fact: It fits perfectly on the wide side of a 1x4 board, so it was the perfect size for where I wanted to mount it on my shelves.
