The flexible system of interchangeable components includes LED heads with pin spacing of 0.2 to 1.2 in. as well as various base units, collimating optics and attachments. Analog and digital drivers are available that permit such control options as a three-position switch, a variable potentiometer, and TTL- or CMOS-based external triggers. The devices generate colors at 455, 475, 505, 530, 590, 617 or 630 nm, or white at 3300 or 5500 K.
