As a child I was a bit of a candle maker. We made dipped and cast candles. Your candle will burn pretty much as you expect. Unfortunately it will not last much longer than a tea candle. For two reasons.
First The citronella impregnated wax is a lower temperature wax than that in a tea candle which means it will melt, evaporate and burn at lower temperatures. This is partly due to the citronella and partly required by the design. In the larger can the outer edges of the candle would not get hot enough to melt a harder wax and you would burn the wick and the center and waste most of the wax. This lower temperature wax will burn faster - perhaps a bit brighter - or just sootier.
Second The purn time of mostly equivalent fuels in mostly equivalent burners is dictated by the amount of fuel. Your candle has about the same amount of wax if not a little less than the tea candle.
A compromise that I have struck - works for me - is the
coghlans candle lantern. I protect the glass by using some buble wrap that came in the package and I stack the interior full with tea lights. This is a bit more bulky than your mint-tin candle but still smaller than the citronella can. It is amazingly light, wind-proof, and bright enough to eat dinner by after dark. I have even used this as a hanging light in a dome tent to no ill effect. I would suggest putting a foil reflector above the hook you hang it from tho for reasons of soot and fire prevention. If you tent doesn't ventilate well don't do this our you run the risk of being short on Oxygen (that's bad) I find that the candles rattled a bit inside the lantern until I wrapped them in bubble wrap as well.
If I were looking for a simple candle the size of a tea candle with only that size in my pack but I wanted it to have a lid I would take an empty tea candle cup and invert it over the full one and tape that shut. Some have even made
alcohol / exbit stoves from this configuration
