Does the niterider lights shine into the drivers eyes? Looks like they do. why would anyone want to aggravate drivers to flash their brights in you face?
Niterider light:
Run Time: 1.5 hours on High (700 lumens)
Fenix BC30: Turbo: 1200 Lumens (1 hour 50min)
I have had a Niterider 600 for 3 years now. It's rechargeable and usually does not exceed my road biking time. I usually run it on medium and rarely run it on high. Biking speeds vary from slow to 30+mph and it performs well no matter what. It's not a brainer, if you a looking for a quality bike light, buy specific cycling light. Case closed.
I still do not understand just how to figure out what lumen count the Ixon IQ is at 80 Lux.
A flux of 1000 lumens, concentrated into an area of one square metre, lights up that square metre with an illuminance of 1000 lux. However, the same 1000 lumens, spread out over ten square metres, produces a dimmer illuminance of only 100 lux.
Achieving an illuminance of 500 lux might be possible in a home kitchen with a singlefluorescent lightfixture with an output of12000 lumens. To light a factory floor with dozens of times the area of the kitchen would require dozens of such fixtures. Thus, lighting a larger area to the same level of luxrequires a greater number of lumens.
