Final specs for the product actually delivered is only 5W LED GU10 / 350-450? lumen / 60 degree angle / 3000KThis product contains only 5W bulbs, so light output brightness lumen is much less than advertised. I have an electrical panel energy monitor with current sensors on each circuit breaker that measures electric usage in watts among other measures, so turning on the track lighting with 6 of these fixtures installed only draws 30 watts of power for 5W per bulb, compared to the halogen fixtures being replaced that drew the rated 50 watts per fixture/bulb. This listing doesn't have multiple products to select within one listing so the specs should not be contradictory / mixed up due to selectable sub-options.The listing title, photos and About This Item description and Technical Details claim different specs for lumen and watts and Kelvin - Description says 700 lumen while the photos and listing title and Tech Details say 1000 lumen and for wattage Description says 7W while the photos and title and Tech Details say 10W, while the delivered product actually only uses 5W per fixture. The wattage/lumen ratio in the specs imply the 5W bulbs is likely claimed 500 lumen, compared to a standard halogen MR16 which is usually rated at 500 lumen but varies by brand from 50-watt halogen MR16 claims of 310 to 500 to 750 lumen.The brightness is definitely 'lower' than a 50W halogen MR16 bulb - it is still 'decent' but depends on your preferences and what you are using the lights for. Beam angle also impacts lumen brightness as the total lumen are spread over a wider area, so that may account for the impression these (60 degree) bulbs aren't as bright as the 35-degree 50-watt halogens being replaced. Overall I like the combo of light coverage (beam angle) and decent less-harsh light output of these fixtures for a medium-task room better than the halogen fixtures they replace, but for a highly detailed task usage you may need two of these fixtures focused on an area, which is easy with a track lighting setup. Of course it would be better to have the flexibility of the brightness from the listing claimed 10 watt / 1000 lumen bulbs, and use a dimmer switch depending on task needs.The listing photos claims 60 degrees beam angle spread or beam angle dispersion while the description claims 36 degrees (vs 21 degree spotlight, 35-38-40 degrees, and 60 degrees are typical ratings), and I would say the beam angle of light coverage is quite wide and the 60 degrees beam angle spec seems to be met.The location of the 350-degree swivel stop varies by each fixture as a positive feature. The H-Track 3-wire config only allows the fixture to be installed in one orientation to the track, so find the stop location of each fixture before placing in the track - if the stop happens to be close to where you want to point the bulb, which would also limit rotating the head over time to occassionally light up different sections of a closet / work surface / section of a room for rare projects like working on open space of a floor / cleaning / painting etc, find another fixture where the stop is well away from your possible range of rotation you might use for that fixture.The listing title and Tech Details claims 3000k while the Description claims 4000k, the delivered fixture is consistent with 3000k warm/soft white Kelvin Rating with good color accuracy.The bulbs have no markings, symbols, or writing of any kind on them when removed for inspection. To remove these bulbs, the bulb is nearly flush with the housing and the outer metal ring attached to the face of the bulb sometimes also rotates freely, so press 2 fingers on opposite sides of the bulb against the inner ring of cooling vent fins to get some grip (rather than slip across the metal edge ring or smooth glass of the bulb) and rotate counter-clockwise to release the GU10 base from the housing.There are so many discrepancies in this listing, perhaps that is why it is selling for $50 for 12 fixtures currently, which is a great deal if you accept the lesser specs.

Remotes with these track lighting heads are never good. Luckily, I rarely change settings but you may want to think about that if you do that alot.Material is absolutely top notch. These should last for decades. The brightness is as advertised, which is very good. Installation, as is usually the case with these, is very simple. Unless your product gets damaged in shipping you should expect a fairly straightforward installation process. Highly recommended.

These seem like a well built track light that look great once installed. They give off a pleasant light are plenty bright enough for their size. The bulb housing is metal with a metal hinge and the base mostly plastic. A common problem with many of these track lights is the safety pull back lock in the mounting base does not fully retract when installing causing misalignment and poor contact with the electrical contacts. These light do not suffer from that problem which is great.With the above said I do have a couple of issues with them and is why I knocked off one star. First, the bulbs are flush with the metal housing and I cannot for the life of me remove the bulbs from the base if I needed to change them. I simply cannot get a grip on them anywhere to unscrew them. Second, I looked for replacement bulbs to get and have on hand for future replacement when needed. I can find plenty of GU10 white bulbs that would work but a can only find a couple of black bulbs of which are not the same design as what comes with these lights. I contacted the seller and they only recommended one bulb but it to was not the same design as what come with the lights which is a real bummer. It will fit but the lights will look different. I don't understand why the same installed bulbs are not available. Good thing these are rated to last 50,000 hours which means it will be many years hopefully before I need to replace one of the bulbs. Maybe by then the proper bulbs will be available.Overall and aside from the bulb issue I really like these light and how they look.

I haven’t gotten these up yet, so I can’t comment on that, but I can say that they look like nice track lights. They seem to be well made and are a good size. I also like that they are dimmable. If I have any problems with them, I will update my review.

Used for lighting mounted on a beam.

Good color temperature on these lights, perfect for task or ambient lighting. Note that, as advertised, they can only dim down to around 30%, so if you're hoping to use the same lights for "candlelit dinner" as you are for "cleaning the house," it'd be best to get some with a larger dimming range. Recommended as noted!

These are okay but the included bulbs are about 70% as bright as the “50w equivalent” bulbs sold at home improvement stores. I’d say the bulbs which are included are more like 30w equivalent. When I went to buy new bulbs (since the included bulbs were so dim), I discovered some MR16 GU10 bulbs won’t fit in these heads because some bulbs are a bit too big to slide down into the housing. I discovered the bulbs made by Feit electric which are made of all white plastic fit perfectly.
