- Outbound Lighting to explain what a cutoff beam pattern is and why it is important for road and gravel bike riders. It is a prominate feature on the Detour Road Bike Light.

This company makes the best lights.
Only if they can be easily opened up and the emitters replaced/reflowed with 90-95 CRI 3200k emitters with the same footprint in order to minimize the Purkinje effect (light becomes too blue at lower brightness settings).
Outbound Detour seems to have the nearfield a bit top close to the tire. Should be at least 1 meter from the tire to avoid any shadows and to have better distance vision according to the Bumm.
There are too many bicycles on commuter paths/trails using mtb lamps with no cutoffs. Wish more would understand how this negatively effects others.
Having a high powered light can be nice. However, if it's not directed well it can be a danger, possibly blinding oncoming traffic. I'm dumbfounded to the fact, that most other lighting manufactures seem to be focused on huge lumen output, yet ignore to offer any lighting with a cutoff design.
Kudos to Outbound Lighting for recognizing the needs of road cyclist. They delivered a complete and well engineered product, for those of us who ride at night.

@@uvwuvw-ol3fg When out at night, when I'm going fast, down a steep hill my vision is well out front, that is beyond the shadows of my wheel. In addition, when riding my bike, I have no thoughts about kelvins. I will think about kelvins when taking a photo.
@@ilovephotography1254 Isn't it too hard for the eyes to focus in blue light especially without ambient lighting when everything else is dark around you?
@@uvwuvw-ol3fg When it comes to the science of night vision and light production for biking, this is well above my pay grade. However, the people at Outbound Lighting are both engineers and bike riders. Perhaps your questions would be best directed to them. They have a website, where you can leave a comment and they're likely to respond.
As for myself I can offer a humble opinion, from my own light experience. The currant light that I'm using, I'm guessing it appears to be around 5500k. The quality of light kelvins that it produces is fine. My eyes can have no problems adjusting at high speeds night riding. This includes riding in pitch black areas or under street lighting with differing kelvins.
My complaint with my light is that the beam is not well managed. The beam is a floodlight. Therefore the light spill will create glare that blinds oncoming traffic, other cyclist and pedestrians. With a cutoff beam the light is channeled to road and the light spill is contained. The "Detour" light lenses are specifically engineered with a cutoff beam for the urban road bike rider.
I haven't used the "Detour" on my bike, so for me to say anything about the light quality at night would be only a guess. The good news is, there happens to be a UA-cam channel called The Sweet Cyclists. His channel has produced many bike light reviews, from many different bike light makers. I believe in the near future he will be doing a review of the "Detour" light. He too is likely to respond to your questions.
@@ilovephotography1254 Turns out the XD16 led emitter comes in variety of colour temperatures and cri so anyone with too much time on their hands can reflow it when needed.
