Does anyone know if its possible to buy an outside floodlight that
will come on at dusk at say 60 watts BUT if anyone crosses the path of
the PIR it will come on stronger say 300w.

The next door neighbor of a friend of mine has just such a thing. I know,
because I trigger it when I go out the back door at night.
A simple way if doing this would be to use a PIR light control, but connect
a solid-state dimmer across its "contacts." That way you get whatever
light level the dimmer is set for unless the sensor bypasses it and kicks
the lamp up to full brightness. Use any lamp(s) up to the rating of the
control and dimmer.

Warning- following seriously OT:
I use something similar to control the hot air furnace fan which has a wood
stove that directs heat into the cold air return. A temperature switch
over the stove turns on the fan through a solid state speed control
(designed to control motors, which aren't like lights). If the furnace
itself comes on, it's stack switch bypasses the speed control, and the fan
goes to full speed.

At least the bok choi doesn't mind the cold.
