I can only comment on the coleman, and red seems to give a good answer above but I'll give my pros and cons of the coleman. Pros, very bright white light, quite light compared to most parafin lamps, fuel doesn't leave things sticky and smelly if spilt (not unleaded), very easy to use, reliable, easy to service, and for me access to a cheap clean fuel source. Cons, made from a steel that corrodes easily (not a problem in use but if you get a second hand one check the bottom is not rusted out likewise dont store on a damp shelf in the shed), got to be v careful with petrol, mantles quite delicate, I don't find the control that good? (seems to work best at full bore or near that, when I dim them sometimes after a little while they just go out), related to above I never get the promised 13 hr burn time I just get the full throttle 6-7 hr.
I can't tell the difference in output between my 2 mantle and 1 mantle so I suggest get the one and there are less mantles to break. Also I found forget the stupid preburn the mantle with a match or lighter which is impossible when out and there is any breeze, just tie the mantle on, reassemble and light the sucker. I havent had to replace a mantle in 18 months now (after saying that I had better go buy some spares now)
