3.12 400-Hertz fluorescent lighting fixtures. When specified (see 6.2), the procedures specified herein shall
apply when 400-hertz in lieu of 60-hertz fluorescent lighting fixtures are required.
3.12.1 Symbol numbers. A "-400 hertz" for standard fixtures or a "HT-400 hertz" for high-temperature
fixtures shall be placed next to the symbol numbers specified in the applicable specification sheets to indicate a
400-hertz modification of the standard 60-hertz lighting fixtures. (Example: Symbol Number 77.4-400 hertz for
standard fixtures or 77.4 HT-400 hertz for high-temperature fixtures.)
3.12.2 Component substitution. The 60-hertz ballasts specified in the applicable specification sheets shall be
substituted with corresponding 400-hertz ballasts in accordance with MIL-DTL-16377/72 and MIL-F-16377/45.
Other component substitution for high-temperature fixtures shall be as listed in table III.
3.13 Workmanship. The fixtures, lights, and parts shall be manufactured and finished in a manner that is
consistent with best industry practices. Particular attention shall be paid to neatness and thoroughness of soldering,
wiring, marking of parts and assemblies, plating, painting, machine screw assemblage, welding, and freedom of
parts from burrs and sharp edges. See Guideline 9 of MIL-HDBK-454 for additional information regarding
workmanship.
