we will soon see claims that this is all self-interest by Trek, whose
sole aim is to sell more lights.


Everybody should know that such articles aren't very suited to foster
sales of their own products but lights in general.

True. But it's a convenient excuse to dismiss the findings of such
article. Even though Trek is not a major supplier of bicycle lights, you
can already predict the narrative that will spew forth. You saw it
already with the Odense study.


Yep, afterwards the usual denialist stuff roll in.


The usual reaction with many brand name lights is "Now WHAT do those
cost?!" and then people scope out Amazon, Walmart, Newegg, EBay and
others. Just like I did.

I don't think that people are quite as price sensitive as you may think.
People do research by reading reviews, then buy whatever suits them.


Some commuters maybe. IME the majority of riders is price-sensitive.
This includes serious riders who put on way more miles per year than I
do. The watch for sales like hawks. Then when their favorite tire,
chain, cassette, BB or whatever goes on sale they pounce and by a
serious stash. Those guys will not spend $200 on a light.


Unfortunately most shops aren't interested in stocking a very wide
selection. I looked for my Lezyne lights at local stores. One store
carried some Lezyne products, but not what I wanted.

I even found that no-name lights can be of better quality than name
brand lights that cost a lot more (not Trek though, I never had any of
theirs).

Yes, sometimes. But the no-name lights often come with batteries whose
capacity bear no relation to what's printed on them.


I can't confirm that. One light came with a battery, the other didn't
and I bought a much larger one anyhow because my road bike rides are
longer and sometimes, well, on roads. Yesterday I had to replenish
brewing stuff which was 37mi round trip. Half of the time the front
light was on full bore (8W), the other half it was off. The Li-Ion stack
voltage sagged from 8.06V to 7.88V over that whole time. Cut-off is at
6.7V so plenty of juice left. It would have sufficed for hours more. The
light including aftermarket lens cost me under $20 and the battery pack
also $20.
