Nothing explicitly stated. I'm assuming you mean strain relief as in attaching the cord to the chain or wire rope that suspends the light?

Here is what 410.62 says in regards to cord connected HID lights. (2017 NEC)

410.62 Cord-Connected Lampholders and Luminaires.
(C) Electric-Discharge and LED Luminaires. Electric-discharge
and LED luminaires shall comply with (1), (2), and
(3) as applicable.
(1) Cord-Connected Installation. A luminaire or a listed
assembly in compliance with any of the conditions in (a)
through (c) shall be permitted to be cord connected provided
the luminaire is located directly below the outlet or busway, the
cord is not subject to strain or physical damage, and the cord is
visible over its entire length except at terminations.
(a) A luminaire shall be permitted to be connected with
a cord terminating in a grounding-type attachment plug or
busway plug.
(b) A luminaire assembly equipped with a strain relief
and canopy shall be permitted to use a cord connection
between the luminaire assembly and the canopy. The canopy
shall be permitted to include a section of raceway not over
150 mm (6 in.) in length and intended to facilitate the connec‐
tion to an outlet box mounted above a suspended ceiling.
(c) Listed luminaires connected using listed assemblies
that incorporate manufactured wiring system connectors in
accordance with 604.100(C) shall be permitted to be cord
connected.

So assuming that you are located directly below the outlet then you should not need to support the flexible cord by the building steel.
