EDLT Lens Repairs
When EDLT lens tubes were first released, ETC required that any lens replacements needed to happen in the factory. This was because the lenses in the tubes were calibrated and matched as a set, and you would not get the full light output of the fixture if the lenses were not matched to each other. However, since then, the quality of EDLT lenses has improved, and the lenses can be replaced without calibration. The tubes no longer need to come in to the factory to replace a lens.
