I have a 160w too. It's not as heat intense as the Mega Ray equivalent, but it's a nice bulb. I also am using a 100w ceramic heat emitter on a thermostat to boost up when needed. A 100w Arcadia combined might not provide enough heat. It's sleet and snow with sub zero temps outside. But also depends on table size and if you can contain the heat in the room and the table.
You might need to add an additional heat source if the temps don't reach into the mid 30's.
Remember if you go for a higher 160w, the holder also must be able to take the wattage. xx
