LED MR16 Spotlight 12V 4W (340 Lumen - 50 Watt Equivalent) 3200K Warm 45 Degree Beam Angle

I purchased these lights on three occasions and have zero failures on (25) running my 12VAC outdoor lighting. I pull tested the connector pins based on previous comments and had no movement or any other issues. The light color is not as warm as the 20W Halogen bulbs I replaced. Wouldn't want this color inside my house, but outside it looks great and isn't far off the Halogens warm color.These lights also fit into my existing $10 Plastic Malibu Spot Light fixtures by unplugging the Halogen bulb and removing the Malibu Reflector. $2.10/light is a great deal for replacement lights.These LED lights produce significantly less heat and should be more fire safe than traditional 20W or 50W lamps.Bulb to bulb consistency was excellent.Lumens seems similar to 35W Halogen, not a 50W replacement as is misstated in the product description.Shipping was reliable at about 2 weeks from China for all three of my purchases.No issues with either of my 300W Magnetic Transformers (using only these LED lights).Energy savings is huge moving from existing 20W - 50W Halogens, to just 4W.I initially purchased a single light to confirm quality and color with Prime 2 day shipping.

I bought this bulb for $10 back in Feb 2012, now it's $14.99.I like that it has light out the sides for my indoor, ceiling, down light fixtures, with glass shades. They're similar to regular incandescent MR16s in that respect. Haven't seen any other LED bulbs that do that.What I don't like is that its light has a slight green tint.Also, the pins on mine pushed in; however a couple spots of super glue works easily, without any waiting time.I agree that the brightness is similar to about a 30watt incandescent. Although that's hard to compare as the beam width varies a lot across MR16 bulbs.I'm now comparing this with the G7 MR16 at $13.99. The G7 has a lifetime warranty (assuming the company is around that long). I bought one of each to compare. (G7 Power is also on Amazon.)They have similar brighness. The G7 color is just about perfect - no green. but it doesn't have the light out the sides.If this bulb were still $10, I'd suffer the greenish tint. But at $1 more than the G7, it's a difficult decision...Update: I just found this same bulb (hopefully) on Amazon, from a different seller: "ledCREElight", for $8.99. Ordered x3. Be careful to check 1) wattage, 2) 3200k, 3) beam width. There are several combinations available. The lifetime warranty on the G7 is very attractive, and it's a nice bulb. But for $8.99, I'm going to go with these and keep my fingers crossed.Update 2: Received and installed three more from "ledCREElight"(Amazon). Just confirming that they are IDENTICAL to this item, but still only $8.99 each (4/29/12). Same color (slight green tint) but with All bulbs the same (no incandescent or other 'warm' LEDs in close proximity), the color difference isn't really noticeable. Even the box for these three was identical, too. Oh, one of the 3 came with a loose ring and lenses. A simple push and slight twist put it back together again. RE: the pins pushing in... It turns out that one of my lamp fixture sockets requires a tad more force to insert the bulb than the other sockets, so that's what was causing the pins to push in. Still, a dot of super glue does the trick.

SEE THE PHOTO of my test results in the product photo gallery for a better understanding.I was quite hopeful for these bulbs. I have been trying to move almost exclusively to LED bulbs recently, and have been pleasantly surprised by the light quality and color of most of my purchases. This bulb surprised me, but not pleasantly.I am a photographer, so I have the equipment to test the light quality of these LED bulbs. In a word...horrible. I measured this bulb in a darkened room about 7 feet away from the light source.The color of the light at the very center is 3300k (close to the 3200k advertised), but moving 10 inches from the center and the light falls to 2700k-- That's a 600k change! The result is that the edges have a very yellow look and the hot spot looks very blue in comparison.Worse than that is the light fall off. In the same distance (10 inches)the amount of light drops by 8x! A hotspot like that defeats the purpose of having a 45 degree beam. In essence it is about a 10 degree beam of light with some spill.I can't think of condition that this bulb could be used in without the inconsistency of light and color becoming a problem (maybe behind a diffuser). I can live with a 2700k or 3300k bulb, and I can live with a bright bulb or one that is 8x less bright, but I can't live with a bulb that has all these qualities simultaneously.EDIT: The photos don't always appear in the product gallery for some reason.

I ordered 20 of them to replace the existing halogens in my landscape lights. So far I installed only one, but it has been good for a couple weeks. The light is an adequate replacement for my 50W halogens with a warm color instead of the ice white normally found with LED's. I look forward to replacing more and saving electricity and cash.**Update 4/5/14** I installed the remaining 19 bulbs with no issues. All work fine and I had no problems with the pins. I am so pleased with the bulbs, I am ordering another 10 for another project.**Update 1/20/2015**Of the 30 I ordered, half of them are now bad. The average life of the bad ones was about 10 months. The electric cost savings (@ $.11/KWH) of 46W versus a 50W halogen is about $.05 per 10 hour day. So, they paid for themselves in about 2 months, but I was hoping for a longer bulb life. I am going to try another version that is designed for outdoor use at slightly higher costs for comparison.
