depends what you are used to – i’ve just started using mine as a helmet light with a pouch battery, replaced a six year old light & motion arc ultra (675 lumens) – although i find it difficult to compare HID lumens with the reported LED lumen figures thb
the arc was an excellent light, with a fanastic beam and excellent battery but did have a very bright hot spot in the centre of the beam but this year after many years excellent service wouldn’t start up
its early days yet, only my third night ride using it this evening, was fine (more than enough light for me), although I couldn’t get it to stay on high setting this evening (either i’m too slow or it was too warm) – it auto switches to a lower beam i.e. lower temp when too warm
no hot spots in the centre of the beam, high quality construction, not used it longer than 135 minutes yet so can’t comment on the battery duration really, and has taken a couple of hard knocks from tree branches already and light enough to run on a helmet and was much cheaper than the alternatives i was considering (SpiderEyes by troutelights and the L&M Seca 1400) when i bought it
plus its ten times better than the Exposure Diablo Mk1 I wasted £200 notes on
