No, I did not mean that!

You mentioned a 0.17 Ohm resistor in series with the lamp;

But you many not get that chosen value easily in the market;

You may have to improvise by using series - parallel combination of resistors- say 1W 1R- they are easily available.

If you put five of them in parallel, you can get 0.2 easily. But match them if possible.

If you put 10 of them in parallel, you get 0.1R 10W resistor. But if they are not matched, there will be thermal runaway.

Great! thanks for the clarification...
