Hi Jeff, well so far we are happy with the anchor lamps and have burned it in 40 knots of wind with out even seeing the flame move. the only thing we had to do was put a rubber band around the base of the inner lamp to keep it from rattling out after a long night of being blown around. i think eventialy it would shake enough to allow the inner lamp to fall out the bottom. but it was a super simple fix. thanks a lot and cant wait to get the new port and starboard lamps.
