We're big fans of versatility here, and this combination laser pointer/flashing LED light is like having two club toys in one. The red laser pointer is the standard push-on style, while the three bright LEDs in red, green, and blue can be activated through 8 different color combination modes: a solid-on of each color individually, solid-on combinations of 2 colors at a time, a solid-on of all three LEDs at once, or a flashing mode that cycles between the LEDs. The cycling mode produces a particularly cool effect when the light is clipped to your jeans or backpack, and any of the modes are great for playing with in a club. The laser diode has a wavelength of 650NM+/-10, with a maximum output of <5MW, and is FDA & CE approved. The body of the LED Laser Pointer is about 3" long, and comes with a keychain attachment and 3 replaceable LR44 batteries. Please note the barrel of the laser pointer comes in assorted solid colors.
