I use the Fenix LD20 now already since May 2012 almost daily as a bicycle lamp in conjunction with a flashlight TwoFish holder for my city bike. I was looking for a bright lamp with, for cycling, favorable light cone and a power supply via standard batteries (AA or AAA). Moreover, they should be handy, durable and waterproof. And that is why the LD20 is very well suited, in particular the wide beams is ideal for this use. For my application in dark corners at night and at night, the lamp performs their service to be outstanding. There was never any problems with the lamp, only improvement possible would be another switch design. The lamp does not remember namely the set light mode, so you have to switch through before each trip (which is however in such tactical flashlights not uncommon). I mostly use the 80 lumen mode and if it is sometimes quite dark, the 180 lumens. Even with only 80 lumens me so far is hardly anybody encounter with a brighter light. For the light output I think the battery consumption (works with 2x Eneloop XX) to be appropriate.
At the clip, pocket and wrist strap I can not say anything, they were never used.
