I am a greedy git, and a collectorholic for anything fishing related.I have a Coleman Northstar, a Coleman dual mantle, 2 x Anchor lamps, and 2 x 500cp Tilleys.
I use them all for beach fishing,and can say without any doubt that the Anchors are the best and most reliable ,they have a terrific bright light, and are easy to light, but,they succumb to rust, so you have to keep them well cleaned and I allways clean them off, and spray with WD40 after every trip,both the Colemans are good,but they do not have the small presure release valve that the Anchors have, so you have to wait until they have cooled off before releasing the pressure.
The 2 x Tileys are bright and reliable,but are somewhat dated now, having to pre-heat the generator with a meths clip is fiddly and sometimes the meths burns off before the lamp has been heated sufficiently tolight.
A tip for anybody using a Tilley or Anchor, or Coleman dual Mantle... dont fasten the mantle on with the string tie, place the neck of the mantle around the atomiser, and twist a loop of soft copper wire around the mantle top, it will stay on far longer than when tied on with string.
