If there were no sharp turns on the MUP or the unlit streets I ride in on (or if I were riding slower), it would be "enough" . . . for me. However, as I said in my previous post, there are other reasons why the Lumina alone, mounted on the handlebars, isn't "enough" for me (note: it might have been "enough" by itself if I mounted it on my helmet - tried it once after I got the Dinotte, but the weight was very uncomfortable).
Side Note: Two of my co-workers have Cygolite 400s (or 450s or whatever it is). Anyway, they got them for the after-work rides I lead (to get them ready for an upcoming 75k ride). Their Cygolite is bright enough on the unlit MUP for them, though the beam appears narrower than my Lumina, such that when I ride alongside or behind them, it's a noticeable improvement even without the Dinotte switched on (we ride pretty slowly so over-riding the beam isn't a concern); once I turn on the Dinotte, there's no comparison.
I use the exact same setup but in reverse, Dinotte XML 3 on the handlebars and the Lumina 650 on my helmet. Prefer to have the heavier Dinotte lithium battery pack be strapped to my frame rather than in my rear jersey pocket. I don't find the weight of my Lumina on my helmet to be uncomfortable (I believe it only weighs ~ 180 grams). I run the Lumina on medium to provide me with ample run time (the XML 3 on high is not a limiting factor for me in terms of run time) and find it works well when cornering or looking somewhere other than where my handlebars are pointed. Either way the two combined at nearly 2000 lumens (Lumina on medium Dinotte on high) will light up pretty much any possible riding condition you could possibly encounter.
