Ordering information

It’s easy to select the right illuminator for your application: our part numbers are coded as LTLAxy-z, where x defines the illuminator size (B = medium, C = large),
y refers to the power intensity (1 = medium, 2 = high) and z refers to color (W = white, R = red, G = green).
For instance LTLAB2-R is a diffusive strobed low angle ring light illuminator - medium size high power red.
