Filters don't do much to single color LEDs like Consular Green. You can get some neat colors with Adegan Silver and the filters, but if you want a solid and powerful green I recommend getting Consular Green.
This. Also, filters reduce brightness so no matter what a single color led will be brighter and fuller than an led with filters. If you're a brightness freak (I'm glad I'm not), then filters are not for you. However, it's amazing seeing all of the unique color shades you can get with a white led and LEE filters.
