Markit wroteThey also have them in DPS - on the parallel road to the Gotso - down and to the left there's a district/street where they only sell lights/lamps. I've seen those there but don't know about quality or price.
That's correct Marko, dunno whether tourist prices though.
Also there is evidently a chandlers in Singaraja has them and similar items.
Bored sh!tless in airport so googling and winding up some Ukranian ratbags.
Gonna be a long day.
