Was breaking out the PM 3G for a bit of testing when I remembered about these E10 bulbs Bruce mentioned.

Absolutely perfect with this engine setup! The wattage consumed by the bulb is high enough to use all the steam this Jensen boiler will provide, but the voltage is low enough that you can turn the RPM's down with the throttle for a pleasant run with this engine. The big bulb looks great as well.
Glad I bought a lifetime supply!

Thanks!
