You have to match each bulb with a resistor as each bulb has slightly different requirements.
Edit: The properties change over the lifetime of the bulb in a non-linear way to make things even harder.
- ferongr 9y agoWhy not use a constant current supply instead? Inline resistors are a very primitive way of limiting current.
- extrapickles 9y agoYou would need one for each bulb as the problem is that the bulbs characteristics are not tightly controlled like they are for vacuum tubes and vary widely even in bulbs from the same lot.
