More powerful then the Led Lensers, better waterproofing and much cheaper. The only area where the Led lenser cames out on top is its focusing system (and weight, but that does not matter for fishing).
Fenix HP-11 has 277 Lumens of brightness Fenix HP-20 has 230 Lumens of brightness
LL H7 has 170 Lumens LL H14 has 210 Lumens
The main difference between the HP-11 and HP-20 is the standard of waterproofing. HP-20 has IPX-8 standard (submerged to 2m) while HP-11 has IPX6 standard (protected against Powerful water jets). Which standard of waterproof is more useful for surf casting is a bit debatable.
Getting hit by a wave would make IPX-6 more useful, dropping your headlamp in a Rock pool makes IPX-8 more useful.
