There is a review of this light on http://www.backpackgeartest.org/ The light has 3 Leds 2 are red one is white. The light has a 3 position switch, 019 the single white LED, 029 the 2 red LEDs, (3) the Krypton bulb. The only complaint I have with ours is the red is light position is after the white on the switch. Rocky
