(Pack of 6) Sunthin 4.5W MR16 Led Bulbs, Warm White, 50w Equivalent, Perfect Standard Size, Recessed Lighting, MR16 LED, LED Spotlight, 320lm, 45°

The LED Bulbs are bright and fit as expected. They do a good job of replacing 50W Halogen bulbs that are high up. However the lighting spread is much more narrow so they're best used as downlights or behind a diffuser, since if they're angled in a way that you can see the bulb they are very difficult to look at.

COOL lights! And I mean Cool as in they run at a low temperature and Cool as in they look good!These are a direct replacement for MR 16 halogen bulbs and damn they look good with their silver grey body, airflow holes around the glass, and air cooling fins on the rear.If you don't know the difference between Gu10 and MR16 - MR16 are the ones with spikey pins on the end which are run by a transformer at low voltage (usually 12V) and GU10 are the ones with round ended pins that run on mains voltage (110v) and need twisting when fitting them back into the fitting. The difference has nothing to do with the bulbs but rather with the base.We replaced halogens in a track fitting in a bedroom with these. Given their warm white description, we're very happy with the light color and output. They are bright enough for our room (we have 5 bulbs in the fitting) and we don't notice any difference in the beam angle. If anything, the beam / spread seems wider as the room now feels brighter - but that may be because our old halogens had a narrow beam / spot angle. In any case, the spread, output, and color are good enough for a bedroom.Using only 4.5W instead of 20w per bulb means a substantial saving per bulb. Taken over 12 or so fittings, that's a saving of around 180W to 200W.I've also used the same bulb in 12v landscaping lighting and they give off a lovely warm glow (we didn't want 'daylight' bulbs for use at night). I would go so far as to say that these are slightly cooler than the usual 2700K warm white - and maybe around 3000K which is just fine by me as they don't look 'yellow'There were no failures out of the box. The only question mark is how long these will go before they need replacing due to failure. Expected bulb life expectance is approx. 50,000 hours !!! But that's not to say they will last that long. If I get 5-7 years out of a bulb in normal daily use, I'll be happy.***UPDATE***Still going strong after 2 years in service. No issues whatsoever and they're just as bright as they were on day 1.

Bought these to replace 50-watt halogens used in RUUD commercial track lighting throughout our offices. Overall, the amount of light they output and the color spectrum of the light is good, in fact I would say they may even be a bit brighter then the halogen bulbs they replaced. The negative however is that since they are used in track lighting fixtures containing transformers which were designed for use with halogen bulbs, they have a slight flicker, which in an indoor setting can become bothersome... even irritating. I would say these would work fine for outdoor accent lighting, or perhaps indoors in certain applications, but in our environment, at least for now, we'll be sticking with the good old fashioned halogen bulbs.

This is the third set of LED MR16 bulbs I have tried in the last seven months. They are performing well so far.The first lights I tested were the Jacky 3000K LED MR16 bulbs. They had a great color rendering - pink and white came out as pink and white in my bricks. The warranty was 2 years, and the bulbs were bright, but the radio interference reduced my garage door remote's range from 50 feet to less than 10 feet. Moving the remote closer to the windshield increased the distance closer to 20 feet.The second lights I tested were the Torchstar 3200K LED MR16 bulbs. The customer service was great, and the they did not interfer with my garage door remote, but 3 of 10 bulbs failed in less than six months. They had a one year warranty. Their color was more soft (yellow) - pinks came out more as brown.Currently, I am pleased with the Sunthin 4.5W MR16 LED bulbs. I had them for a month. They have a three year warranty. The reviews are better. The color is whiter and brighter than the Torchstar, but a little softer that the Jacky bulbs, but still good. They don't emit radio interferrence with my garage door. They are a little shorter than the Torchstar and Jacky bulbs. Like the others, they will fit in the Paradise GL2272 Aluminum Light Casing. So far, they are performing well. From my previous experience, time will tell. I had them for a while. No problems so far.

I installed a couple of these bulbs a couple of days ago, and they seem fine. They are mixed in a fixture with a number of MR16 halogen bulbs and while the halogens throw off a lot of dramatic light at the socket, the Sunthin Leds appear indistinguishable at the target area.

So far, so good for these. They are in a track lighting system in my home and replaced halogens. The ones I received are definitely not warm white, they are very bright. It worked out OK, but I will get a different color if I ever change them.

I purchased this to replace more MR16 bulbs in my landscape lighting. These are by far the best among these various brands I have tried! The color is the closest to the warm tone of the non-LED bulbs. They are extremely bright. This single chip LED version has very focused light beams and the 45 degree angle specified is quite accurate. Even though this is only rated at 4W, it can cast beam to light up even the tallest trees. I initially purchased the 5w version of the same bulb for taller trees. But to my surprise these works just as good. I can hardly tell the difference between the 4w and 5w. The only uncertainty is how long these lights can last. Only time will tell.

I have a few rooms in my house with the 12 volt halogen version of these lights. I started swapping them out and none of them seem to work. Right now they flash on correctly, and immediately dim so much that you can barely tell they are on. I bought the 6-pack and have that problem with multiple bulbs.Not sure whats wrong, but they dont seem to be working correctly.
