Quite. It's all about the amps, anyway and most of these lights work with small currents. (An indication LED needs about 10mA for instance, which is still a lot.)

For instance large neon signs don't require particularly much power, they work similar to LED's only at much bigger voltages. So if you have a neon sign which operates at 10-20kV voltage, and assuming current draw is about the same as an indication LED (surely wrong but you get the point) then that's still only 10-20W of power.
