I don't know. There are moments I think "what a wonderful flashlight, so easy, just on and off". But there are also moments I think "2 or 3 brightness levels would be fine". But overall I really like it. It's the C-Version of the L4 and it's bright enough for edc and the quality is superior. It's one of my favourite flashlights I own (since 3 days ;-) ), together with my Elzettas. Thanks mate!
