$69 is cheap, but I wasn't able to find anything close to that price anywhere on the web, but like you said it was probably a special. 150 lumens is great for about 10 mph, anything much faster then that and you could run into surprises that you don't want. If you were like me when I was young I had unusually great night vision and a simple 13 watt halogen was great up to about 20, but as I got older my eyes slowly dimmed, so now at 58 I ride with a light capable of 480 lumens, but I only run it at about 150 in the city and 300 on dark bike paths.It was on special for $69 the other day which is why I think the person purchased it for me. Is 150 lumens in-adequate? It is certainly a step up from what I'm using now.
See the REI daily deals. They ran it on 11/20, different deal everyday on some great outdoor products.Weav, Where did you see it for $69? For $69 I would consider getting another to use as a helmet light.
Speaking for my 3 yr old 110 lumen model, I think the brightness and pattern is adequate, even for very dark roads. I do have to keep the speed down around 12-15 mph, otherwise the light doesn't' reach far enough for me to react to road hazards.
