Nuvo Lighting TH302 Gimbal Ring Track Head, Pwt, Nckl, B/S, Slvr

These track lights were installed by the builder in my new home. While I like the design and appearance of these track lights, the base (the black cubic area that connects to the track) is made of cheap plastic which breaks (fractures). In the past few years, I have needed to replace four of these heads due to the exact same failure. In fact, I have replaced the heads (due to failure) more often than I have changed light bulbs.If you are installing new track lighting, I would highly recommend that you avoid this track light system. If you are hoping to replace a lamp head in an existing track light, you might seriously consider replacing the entire track light, instead. Otherwise, you forever be replacing lamp heads (as they fail) every year or two. If you decide to keep the existing track light, you might consider ordering at least three of these as spares.As other reviewers have mentioned, there is a "trick" to removing and replacing the lamp heads. You should probably practice with the replacement lamp head before you climb the ladder. To remove: (1) pull down on the black plastic base cover so it slides back; (2) while holding the sliding part back, rotate 90 degrees so conductor prongs line up with the slot in the track; (3) pull head out of track (this should require no force; if head does not come out of the track, then the prongs are not aligned with the track slot). To install: (1) pull down on the black plastic base cover so it slides back; (2) while holding the sliding part back, insert the end into the track slot, then rotate 90 degrees to engage the conductors; (3) release the base cover; (4) adjust the angle of the light as desired.

Works - though the spring clip retaining is a problem with finned/non-smooth lamps such as the LED lamps that use the outside surface of the lamp shape as a heatsink and have ridges. That is a problem of the lamp design and not necessarily the gimbal lamp mount -though a different retaining system could compensate.Interestingly enough, getting the them to work initially took several tries. I think you can only turn them ONE of the 2 directions to seat in the track.Initially I had the track up and plugged in the power puck in the middle, and a gimble light with a bulb and nothing. No power. Measuring showed 110v at the wires to the power puck but no power on the track. Eventually I fouund that rotating the puck into the track the OTHER way and it seated and provided power. The same seemed to apply to the heads here - as they all work so long as I can see the same writing on the turn-in puck block once they are seated.

The lamp mounting with this item is a bit unusual: The head of the GU10 bulb (not supplied) is affixed to the gimbal ring and then a SEPARATE power end connector is clipped onto the two electrical connector posts on the back of the bulb. It's the bulb itself which supports the power end connector. Now, isn't THAT just NOVEL! I say "bare-bones" for this item because its design is about the simplest (and lowest cost) of all track heads I found. 'Course, this design also makes for other possible problems like the end connector coming loose - or even the bulb, itself, while trying to readjust the track head. ('Haven't tried it yet - 'just anticipating....what with prior experiences with similar "weaknesses" in other products. Yeah, I'm considered to be an "expert" in the field. Believe me, I've earned three doctorates in the School of Hard Knocks!)I ordered LED bulbs instead of halogens for this track lighting project and I am finding the LED bulbs are somewhat smaller in diameter, making the spring clips in the ring push the front of the bulbs to the outside of the ring mountings. This won't be a problem unless the restriction of the cooling vanes in the bulbs with this non-centered mounting give problems. 'Not really anticipating a cooling problem, though - these are only 5-watt LED's. From what I saw in other LED bulbs fitting into OTHER track head assemblies, the problem is usually reversed - the LED bulb not being able to fit into the assembly in lieu of the regular halogen. I used these LED bulbs: (copy & paste)http://www.amazon.com/gp/r.html?R=WY5BL37WGREP&C=3T5MUR8F9569O&H=CSR8QGOASTLJYILKD533A5FBBX8A&T=C&U=http%3A%2F%2Fwww.amazon.com%2Fdp%2FB008OCAST4%2Fref%3Dpe_385040_30332200_pe_309540_26725410_item(EVER 5W GU10 LED Bulb, 50W Equivalent, Warm White @ $8.99 ea.)Also, getting these mounted into the ring/clip assemblies won't be a problem if you're the least bit nimble with your fingers. 'Just hafta push on one of the spring clips while inserting (and slightly rotating) the bulb into place. 'Piece a cake after you've done it once.All in all, I'm satisfied that this is exactly what I had expected when ordering. That's why I'm giving this item 5 stars. Just be aware of the info stated above so's not to come up with any disappointments later!THIS IS A FOLLOW-UP (added later)concerning how to alleviate a possible problem during adjusting the track head after it's mounted on the track:After working with these, I've found that you'll not have trouble with adjustments of future lighting positions. In order to insure the power end connector or the bulb from becoming detached during adjustments, all you need do is form or bend the wiring going from the track head to the end power connector to conform to the new position. The wire is fairly stiff and might pull something loose if you don't include this little ditty with your adjustment.Oh, what we'll do to have a "bare-bones" track head! I think it's well worth it, though.

I had ordered a number of these units previously, and I had to do a slight modification to fit a standard bayonet-mount LED bulb (remove a clip on the wire so that the socket could be pressed higher into the head). I reordered the same unit, but the domed screen on the top has been reduced in size compared to the older ones, leaving no room to fit the bulb. I had to drill three holes at the very top of the head to accept the cir-clip that keeps the screen on, in order to make just enough room for the bulbs.

This is for Type H track.I have Type J so had to return as it didn't fit.See attached picture.Too bad that info is not in the description.

PROs:easy to install, looking good, relatively easy adjustment/positioning of the headCONs:the bulb is sitting in unsupported (held only by a steel ring) which makes it hard to position it properly in the tight space. My solution: use bulbs no longer than 2.09 "/5.1 cm/ and preferably with anti-UV glass (that would allow you to get rid of 3mm thick UV filter provided by manufacturer thus giving you more space and better cooling).

works great

Added this to the track I bought. Actually there were plenty of room on the 3 light track for 6 fixtures if you want to add more as the fixtures are small.

Le système de retenue de la grille arrière n’est pas très rigide!!!

This item is a perfect match to the ones included in the track light kit.

Simply perfect ! fast shipping

This light is excellent.

All good

They don't fit standard track, total wast of time and money

Great Lights - task oriented,

satisfaite du produit mais pas du connecteur qui n"est pas assez de force et l"on doit en mettre un de couleur blanc ou noir seulementc" est decevant car le tout est de couleur nickel
