I am using RAYOVAC Spotlights. A friend recommended this lamp after using one for some months as bright and rugged. In terms of the quality of the light, I can say that this product is one of the best. It can produce up to 750 lumens and up to 430 meters of beam distance. As a boat owner, that is a huge light output that can help when navigating in darkness. I also like the trigger switch which gives you the ability to choose between three energy-saving modes.
