The new Wilma seems slightly brighter than my L&M Arc (according to Lupine datasheet, anyway). So, when my good, old beloved L&M Arc passes away due to old age, I'm thinking about replacing it with Wilma. Only one unanswered question though - why does'nt Lupine offer higher capacity batteries with their new Wilma? It seems that their best Wilma batteries are rated at 9ah, while Edison has ~13ah batteries.
