Questions about this item

How much heat does the 660 W rating produce when the lampholder runs continuously?

The 660 W rating is the maximum lamp load the holder can carry; actual heat depends on the lamp installed and ambient ventilation.

Which wiring components must already be in place for the screw terminals to connect?

You need 18 AWG conductors and a 600 V AC circuit with slide-on mounting provisions.

Will this Fa8 lampholder accept the older 3/4 in, 1 in and 1 1/2 in diameter tubes I already have?

Yes, the holder is listed for bulb diameters of 3/4 in, 1 in and 1 1/2 in with single-pin Fa8 bases.
