Old style ones where just a standard light bulb, not sure how the modern ones work. So no more than a regular light fixture, just less light output for the wattage.
Lava lamps function by heating the wax/goop in the glass bottle to the point where it becomes liquid. So you can either use an old style light source that generates that heat (thats how they still work afaik) or you use an LED + a separate heat source.
So total energy usage could only be reduced in the LED version by more efficiently transferring heat directly to the glass. The light bulb doesnt have direct contact so there is a layer of insulating air in between which means lots of heat goes to the room instead of the glass.
A third idea would be a different wax/goop that is just always liquid, but that doesnt work well because the movement of the bubbles comes from the wax getting heated at the bottom, which makes it rise to the top where it cools down and then drops down again.
Yeah, I still have an old one around. Was just guessing that maybe with the old incandescent bulbs becoming a rare thing maybe they switched to LED and a dedicated IR bulb like they have for reptile tanks. Could make for some interesting effects since you could change the light color that way too.

According to Technology Connections the “modern” lava lamps still use an appliance bulb that is incandescent.
Have a newer one from 2019.They use the least energy efficient bulbs that are still for sale in the EU. Energy class G.
Welp they still need to heat the oil and the lightbulbs output was like 90% heat anyway
