exactly what type of "bulb lighting" are you looking for? String lights with
LED filaments are available ,in varying lengths up to 50 feet, at both Lowes & HD. Just plug them in. They will also have, if not now - soon, a string of about 10 light bulb looking globes on a 15 or 20 feet long outdoor wire.
Hope this info helps.
Ana, try out these websites - http://www.partylights.com/Strings-Bulbs/C9-Strings-Bulbs and http://www.hometownevolutioninc.com/String-Lights-and-Bulbs.html?gclid=CNCgg6aF_q4CFaRdtgodOl5u1g I have used the G50 clear bulbs and they look a lot like the Emerson bulbs that everyone has become very interested in lately. I hope this helps.
