Wedge base (like the 921 & 922) leds are available in a variety of brightness (lumens) and colors (cool, warm, amber, etc). If your source doesn't include the specs for lumens and color temperature, go to a different source. I use rvledbulbs.com - they have excellent product info and the the full manufacturers data sheet for most of their led products. That way I know what I am getting. They also have a 100% satisfaction guarantee, so you can return it if necessary.
