Your Princess auto link didn't give a voltage range, only it was "12V"..

Couple of things to me that raise flags..
12V and .67A is actually 8.04W, for it to be 8.4W that would mean the "operating voltage" would be 12.5V.. Running them above 12.5 is going to be a real gamble for sure and indicative of much of the cheapo import stuff..
Second, 324 Lumens for 8.4W is extremely poor, about 38.6 lumens per watt!
Good quality LEDs should be closer to 3W-4W (80-90 Lumens per watt) for that fixture with that Lumens rating..
Granted, they are more efficient than incadescent, but for modern day LEDs they are junk.
Doesn't state the color temp or Color Rendition Index (CRI)but I would guess that it is most likely a rather harsh blueish temp of 5000K-6000K and CRI well below 70 which means a lot of color shift (changes the color you perceive of things around you)..
Oh, another red flag, 8,700 hrs of life? Yeah, those LEDs are way over driven, at least they didn't lie about a "long life" but still the expected life should be upwards of 50,000 hrs or higher..
Personally, if you still have the original incadescent fixture I would put that back in and buy some LED replacement bulbs of much better quality!
