Yes. You can use a Pronto and an IR543 to turn lights on to a predetermined brightness level, if you use PCS brand switches or PCS brand lamp modules. The PCS products are programmed to remember different brightnes levels and they can be "triggered" to go to those levels with one X-10 command that the Pronto can provide. We are an authorized PCS dealer and installer and have all the programming information necessary to accomplish this. We offer PCS switches in 600 and 1000 watt load capacities, and lamp modules with a 800 watt load capacity.
