Color Code Guide for All ETC Lenses
All ETC lens tubes use a system of color coding to denote which lenses belong in which lens tube. The chart below breaks down that color code to aid in identifying loose lenses and lens tubes with missing labels.

5° and 10° Lens Tubes
5° and 10° lens tubes use polymer lenses instead of glass and do not use the same color system of identification. Instead, they're best identified by diameter.
| Standard | XDLT | |
|---|---|---|
| 5° | ~12.25" / 311mm (7060A4024) | ~15" / 386mm (7462A4024) |
| 10° | ~10.25" / 260mm (7060A4025) | ~11.8" / 300mm (7462A4025) |
