We've replaced our anchor, tricolor, spreader and running lights a couple of years ago with Dr LED bulbs and have been very pleased.
Inside we've gone to Sensibulb and Dr LED but a friend showed us a light that was a lot brighter than ours. I'll need to email him for the brand (Marine Bright?).
We also use a couple of Bebi lights to light up the boat at anchor for safety reasons.
We spend a lot of time on the hook and consider the LED's to be crucial for battery management.
