Moderator, please do not move as the G4 bulb is mainly used in Class As.
I recently installed these new style LED COBB bulbs...Ebay, cheap, China which is where I buy all of my LEDs. Over the last 10 years I've tried various style LED bulbs and recommend buying 15X G4 with 12 SMD, 5050 size chips in warm white to replace your halogens...$10.08 delivered (68 cents each) and last link.
The 8 7W Cobb disks are $11.44 ($1.43 each and first link) and arrived fairly quickly from China. I'm impressed with the amount of light they put out...more than the halogens I replaced and more than the 12/5050 LED bulbs I normally recommend. You can see 30 small round chips in them which concerns me as the only LEDs I've not been happy with are those with smaller chips than the 5050 size. Time will tell how well they last and they look better in the pucks that you can see in the ceiling. I would not buy the 12W as they are to large to fit in the pucks.

Picture does not show much other than they are bright:
I did buy some other 7W Cobb bulbs and do not like them as well as the above:
