Thats if yo have an oscilloscope handy of course !
Stewart,
This type of measurement would be too far off, the resistive load of the lamp,
will probable be less than 10 ohms. Can't use a 12 volt lamp, a 100 watt transmitter
into a 50 ohm load is 70.7 volts. You can use a 115 volt lamp, but the resistance offered by
the lamp will be off. Amateur radio operators are concerned about the actual power output from
their transmitters.

I am well aware of using a lamp as a load to the transmitter,
I was just indicating that if you are concerned about the actual
power the transmitter is delivering to a 50 ohm load, lamps
would not give you a true indication due to not representing a 50 ohm load.
It is ok for indicating the transmitter is functional.

Presumably you're either not a Radio Amateur, or you're only a recent one
The light bulb technique is an old tried and tested solution for Radio Amateurs - I seem to recall you were even tested on it in the RAE.
