LED high mast light fixtures are specified by Special Specification 6156. SS 6156 includes all the other mechanical and electrical parts listed in Item 614, so for a LED high mast assembly, SS 6156 would be used in place of Item 614.

TxDOT LED high mast luminaires are able to use 6 fixtures to light the same area that is lit with 12 TxDOT HPS fixtures. They are designed to be a direct replacement for a 12 fixture HPS ring, and have the same distribution types A, B, and S.

LED high mast luminaires are not currently on an MPL and require submittals for each project. However TRF has reviewed several brands and may be contacted for assistance in evaluating whether a submitted luminaire meets specifications.

LED high mast luminaires do not currently have sampling and testing requirements.
