Questions about this item

How much power does the 415 W ballast draw and how much heat does it add to a sign cabinet running continuously?

The unit is rated at 415 W input; that power becomes heat inside the enclosure, so plan ventilation for the full 415 W load.

What lamp holders and wiring must already be in place for the ballast to strike 4, 5 or 6 T8HO or T12HO lamps?

You need sockets wired for 8 ft to 48 ft total T8HO or T12HO lamps at 120 V or 277 V AC, plus a grounded supply circuit.

Will the ballast start reliably in an unheated sign that sees -20 °F winter nights?

Yes, the minimum starting temperature is rated at -20 °F, so cold starts are supported down to that point.
