Why do you want 240v?? Just get a supercheap 12v fluro, they dont draw much power.
Having said that I've always used a gas lantern, untill the glass and mantle broke
. Now I got an unbreakable mesh cover, just need a new mantle
. I like them cause to me, they just add to the atmoshpere. The dull glow, and faint hissing noise. Also use very little gas so a small bottle should last a week of camping easily.
Another option is the 'pump' up kero fuel ones, they are pretty exxy ($80 IIRC) but very sturdy and last a lifetime from what I've heard.
