Mattr talking bollocks. too much light at 480 lumens? you're having a laugh. sunlight is about 32,000–130,000 lumens per square metre.

I can confidently say i can see better with my hope 4 set on full power (980 lumens) than i can whith it set on half power. and even that with it's entire beam concentrated on one square metre is still between 0.75% to 3% as bright as direct sunlight.
*shakes head* *gives up*

Don't give up, this is a good spectator sport.

Probably for the best. now don't forget to tell those rally drivers that they'll be able to see worse with all those silly lights on the front of their cars because the shadows will look like they are in the wrong direction.

Not really. We should discuss the benefits of helmets instead. Seeing as martin appears to neither drive or ride on anything except glassy smooth roads and trails.

erm, yes actually. Most night stages are on gravel roads or tarmac. But anyway, you carry on.

Ah, right. and i suppose that if they do a night stage that's not on gravel or tarmac they take all those silly bright lights off do they?

Can I just ask at what point do your eyes start using their low light sensors as this may have a bearing on the amount of light you need. Also I have heard that your peripheral vision in low light is better than looking straight on so should I ride in the dark with my head at a jaunty angle whils looking out of the side of my eyes for greater safety? Finally, as your eyes adjust anyhow to light levels is it safe for everything outside the beam to be in total darkness, surely you are likely to be decapitated by a low hanging branch or something aka Steve McQueen?

quick answer - no. at the light levels you use for riding at night even with crap lights your cones and rods will both be functioning just fine so it's not an issue. more light = better, obviously depending on beam spread and diminishing returns. hope 4s put out a lot more light than a hope 1 (4 times as much, obviously) but the central spot isn't that different as most of the extra light goes out to the edge. once you get past the point where you eye just turns down the light levels you won't see any better for more light but bike lights aren't anywhere near that point yet.
