Engineering reference

Selecting within the RT-HPH family.

There is one configuration, so selection is a yes or no against the ambient and mounting. Confirm the measured ambient sits inside the documented range and that the 120° distribution suits the mounting height before ordering.

RT-HPH is a one-model family rather than a wattage ladder. It exists to put a conventional round high bay form factor into a bay that a standard high bay cannot survive, which is why it is listed under both high temperature and high bay.

Common questions

Useful answers before the next step.

These answers clarify the selection process without replacing project-specific documentation.

Is more than one wattage available in this family?

No. The family is a single 240 W configuration at 31,200 lumens. If you need wattage flexibility in a hot bay, look at the EDGE or RT-IL families instead.

Why does RT-HPH appear under both high temperature and high bay?

It serves both selection paths — a high bay that happens to tolerate heat, or a high temperature fixture that happens to be a round high bay. Either way, this is the family's complete specification.
