A330 FCOM 3.04 quote
Airbus states in their A330 FCOM - Operating Speeds Definition:
"F : Minimum speed at which the flaps may be retracted at takeoff. In approach, used as a target speed when the aircraft is in CONF 2 or CONF 3. Represented by “F” on the PFD airspeed scale. At takeoff, it is equal to about 1.18 VS of CONF 1 + F, and is limited to a minimum of VMCL + 5 knots. In approach, when the aircraft is in CONF 2, the takeoff value is increased by 14 %. It is limited to a minimum of VMCL + 15 knots and to a maximum of VFE CONF 3 - 2 knots. Then, when the aircraft is in CONF 3, the takeoff value is increased by 4 %. It is limited to a minimum of VMCL + 10 knots and to a maximum of VFE CONF FULL - 2 knots."
Oh, and indeed: on the A330, after an RTO, or on the ground if the batteries are the only source of power; the Dome light indeed illuminates.
