Agreed. Denali notes a "beam distance" of 423 feet using TWO lights.
This has very little to do with a rider's visual recognition distance.
A lux value of 3.2 (.3 foot candles) is needed and that distance is surely MUCH less.
These lighting advertisements are tricky, much like those for computers.
It takes all facets working together to be good - not simply one.
I would only be using them to increase my conspicuity during the day and to augment my stock headlights the very few and rare times that I ride at night. Still haven't done the EB relay to brighten up the stockers.
They'll throw a 10% beam angle on the low setting and 25% on high.
Nice but a bit big for 4 Cree XM-L2. And I'll bet it's expensive.
**** good leds btw - it's what I used to convert my Triumph Fog lights to LED.
Things like those Denali's you can find on e-Bay much much cheaper. Say 30 bucks.
You can do a very neat home grown Daylight Lamp /aux night lamp for about 10-15 bucks using torch components. I made a set for my mate Jim in the US.

Every now and again I come up against an oncoming motorcycle that has lighting that is way beyond overkill. If their setup is causing me to see spots in front of my eyes or worse during broad daylight with a tinted visor and sunglasses on, then I consider them a hazard.
