Excellent LED bulb that gives life to a nice little Maglite ML5 (5 D batteries). Even used, the batteries allow a powerful light bulb with this by offering a beautiful white color light beam. We pass a questionable lighting 3m true comfort view 15 / 20m (with my batteries, I have not tested with new batteries). A hair bulb expensive but probably permanently extends the life of our venerable Maglite!
