At 35 and 20 lumens I do not think they're good for daytime though. Some of the daytime lights rated at 80 lumens or so are questionable if they're bright enough.
Well, the original Cygolite Hotshot which I have has 30 lumen & is very visible during the day. I know because I have one. Its beam is too narrow so while it's great for the night, daytime is not hotshot's forte. It looks like the Serfas has that serrated lens for wide distribution & 5 more lumen brighter.
