Hi, received the TK red filter, it's really nice, the red is really RED if u know what i mean, it preserves night vision and that really helps when i am outdoors. I will try to take some pics, but if u have a need for a red filter, the TK red filter coupled with the TK20 may work for you. Its pretty bright though so you might also want to consider other lights. e.g Surefire Aviator A2 (red)
