Question about a point made in Art of Electronics
In any transistor circuit the collector current will only be \$I_B\$ by \$\beta\$ IF whatever it is connected to can supply that much current. 

In this case the lamp is rated at .1A at 10V (1W), so, once in a steady state, the collector current could never exceed that even if Vce could be set to zero volts. If we assume a \$\beta\$  of say 50 and the base current is \$9.3mA\$ the theoretical max collector current would be \$0.465A\$, which is well above the \$0.1A\$ the lamp can supply at 10V Vcc.

Of course, initially, when cold, the lamp resistance will be a lot smaller and more than 0.1A will briefly flow up to a maximum of \$I_B\beta\$. If you know the \$\beta\$ value, you can therefore use the base resistor to limit the inrush current in the lamp.

Lamps will emit heat and light at pretty much all voltages. At 9.95V the bulb will still be glowing almost at full brightness. The current will not, in fact, be quite as high as 0.1A. However it is still a lot less than the \$I_B\beta\$ value which was the authors original point.
