I prefer oxygen candles, personally.

  My dad was on submarines and talked about these. Do they also provide light, and if so what color and intensity?

    They burn at 600C (1100F) so I don't think you'd want to view the reaction directly; usually they have to be deliberately contained to contain the heat to sustain the reaction. https://youtu.be/g3Ud6mHdhlQ?t=738 https://youtu.be/g3Ud6mHdhlQ?t=738 (linked to correct timestamp) shows the remains of a burned one and loading fresh ones on a submarine.

    Depends on what state the oxygen is in and any other friends who may react/combust with.
