Some of the newer
IQ-XS lights are 80 lux, which is the same as the Cyo Premium models. And for my money I like the IQ-XS or the
Cyo T Premium for side visibility. Not the
Cyo R(T) Premium. The first one has an extra set of lights for daytime riding and a more bulging lens for better side visibility. The latter has a more focuses beam, which is very visible on the ground but makes for a much narrower beam which is less useful on dark roads. On the other hand that might be exactly what you are looking for. Even under street lights the RT model shows a noticable white beam on the ground.
Otherwise you can always go to
Laempie.de and order a modified B+M light with a flood light switch. The
Luxos can go from 90 to 130 Lux that way and the
Cyo to a 60 + 85 Lux mode. The
IQ-X turns into a 400 Lumen dynamo light that way but I never really liked the side-visibility of the IQ-X.
See the difference at 0:14 when it switches between normal mode and floodlight mode.
