921 LED replacement bulbs

42-SMD T15 12V LED Replacement Light Bulbs from Amazon. I used these in our shaded wall lamps.

I simply put 48LED panels in place of each 921 bulb. :)

We replaced our standard bulbs for with LEDs for the same reason. We'd sit on the couch with the light just above us and you could feel the heat coming off the fixture. I used cheap Ebay 48 LED panels. 15 bulbs for $21. They come in various intensities and light quality. And they have adapters for several types of sockets, including the 921. We're really happy with these.

We had low light problems in the toy hauler area. Light gave off a yellow tint, was hot and not bright enough. Added an entire LED fixture from command electronics on the wall as well as replaced the 921 bulbs in the overhead lights with their LED panel and lens. Big improvement, low amp draw and warm white light. I had bought some LED panel inserts on ebay, great price, I just did not like the light output. The pic is not the best, but the light on the left is command electronics LED strip and lens cover, the right side is the ebay one with original lens cover.

Buy one or two of what you think you would like and try them. If they suit you, buy what you need. Everyone seems to like something different.

Differences in fixtures, area to be lit, etc, etc, vary greatly.

The thread right below this is mine and how I did it, others have posted their experiences with links to where they got them.

We love the 48 1210 panels. You can get them for 10 for $18 and they are easily the brightness of the original bulbs. So much so that we bought smaller units for a more mood like setting.

Be carefull when buying from this company I ordered exactly what they pictured in the link and they sent me 15 little leds with 5 leds on each one. I am trying to make it right but so far they are not responding. Some how they even went in and even removed the picture on the order and its blank but the description they could not change.
