Question: Is it normal for these to make a small buzzing noise?
Document: Be sure you look at your bulb this works great in applications that need  light in one direction. If you need 360 degree light they make a tower style that would work. Check before you order.
Nice light. Works real well where there is room enough in fixture. Good quality and price. Good service and quick shipping from vender. Make sure pins are aligned properly in socket so light fits ok.
I live in my 40' motorhome, and although I like to stay where the sun shines, there are dark nights from time to time. The oem ceiling halogen lights are bright, do a great job, but they are power hogs to the 12v system, and they get very hot.I have two sizes of puck lights in the ceiling, 10w and 20w. I have replaced most now with this make of LED lights and couldn't be happier.
I bought just 8 of the LED lights because they are not cheap and I wanted to make sure I liked the light quality before replacing all the lights. There is a pronounced reduction in the heat they throw and in the power they drain.You can't tell them from the Halogens when the lenses are installed. In fact this weekend we had a friend staying with us and she was sitting under a cluster of 4 of the new LEDs telling me how she had tried LEDs and hated the weak blueish light.
I ordered 10 as a test and they were far superior to other brands that we used in the past. The pins are strong enough to hold up to tight installations (previous brand broke the pins trying to install or remove). We ended up replacing 60 puck lights in our motorhome with these leds and are very happy with the results. No more running around clicking out lights as they don't get hot and use very little power. These make a huge difference to the battery load when dry camping.
I bought five of these to replace the halogen bulbs in my IKEA Non and Grundtal under-cabinet lights. The Non's magnetic transformer (heavy brick) worked fine, but the Grundtal's electronic transformer (lightweight box) made a loud buzzing sound. Apparently the LEDs don't provide enough of a load. The solution: keep a halogen bulb in one of lights.
I replaced all my under-cabinet halogen bulbs with these G4s from BrightChoice. They match the color and brightness well and use just a small fraction of the electricity. In addition, they do not get hot like halogens. I highly recommend these. Sometimes it was difficult to push the pins in the holes (one of the pins broke off on one of the lights), but that may be a problem with my fixtures.There is another brand of these lights that allows dimming.
these lights are really great, i have them in a few placed in my house and am very satisfied with their performance
Will see how this holds up outdoors over time since my lighting fixtures are not completely sealed. [Update: 10 months later all 6 of my lamps are working great. Highly recommended.]
We are very pleased with these lights. They are much brighter than our previous LED bulbs. They don't seem to use much power.
