It does look impressively bright indoors, but on the bike... you'll soon see why I said you'd need at least two. It's casts a wide beam. Just one on these:The front headlight in pic (two of them), seems decent quality plastic and is bloody bright, nowhere to put it yet though as not sorted out handle bar too busy problem. It comes with a remote cable and button for the audio 'bell' not that loud and makes some strange noises but seeing as I don't have a bell...
So far: 9/10 - based solely on initial impressions

... is 4.89 times as bright (1800LUX vs 8800LUX, measured mid-beam using phone luxmeter app at 60cm). First time out with the 1800LM, I reckoned it was about the minimum level of brightness a cyclist should use. However, it's beam is narrower, illuminates a smaller area than I needed when angled down pothole spotting, so I got another for more coverage, then another 2400LM to illuminate a bit further up the road, for when I'm going fast. Together (with the 70LUX on the fork), they form a decent enough pohole kill box.
