Sample tech info:
Q: Is the smoke canister rechargeable or do you dispose of it after use? Is there a gauge to let you know when the canister needs replaced?
A: The canister is rechargeable with any commonly available smoke source, as long as it is composed of copper, PVC, and/or cotton. Whilst it is recommended that harness smoke content be measured with a voltmeter, it is considered acceptable practice to hold a Zippo lighter up to your lamps to see if they're burning, as recommended in the owner's manual.
