The electronics on the back are all in one chip, so this is a really small light compared to other versions, see backside photo. Easy to fit in the fittings (depth-wise).
Had to trim some of the pins to make this properly fit in my ceiling lights (small 6cm fitting with a reflector) Also had to bend the pins a bit smaller, but I have no problems with this.
The color is nice, very close to the old halogen bulbs I just replaced. I think this is an actual 2700k LED. Light is yellow, a bit greenish though...
EDIT a day later:
BAD NEWS, This morning the lights were off and didn't work at all!
See the photo for what happened; they completely BURNED OUT! Glad my house didn't catch fire....
Probably the combination with my dimmer/transformer; I did notice a slight blinking. Was going to check that today, but I guess too late.
EDIT another day later:
Incredible customer service... they contacted me very quickly and saw my review as a complaint even though I meant it as a warning to others not to use this product with just any transformer.
I had an electrician look at it and he advised a different transformer/driver for use with LED lights.
Customer service offered me a replacement, so I am glad that I can finish my project now.
EDIT about a week later:
To complete the story... The transformer I had used apparantly was a 12v AC transformer and these lights are 12v DC. So the lesson is, do not use your halogen transformer, that will fail.
I now have a 12v DC transformer and the lights look very stable on this one.
I finally went with a 3000k light, 2700k was a bit too warm for the place I used them, but that's another story.
