Question: Will the light reflect off of street signs at night? Will this light be good to use on an unlit path?
Document: I am happy with the quality of this bike light and it's nice and bright for my purposes: short commute mostly on a well-lit street. I do have to ride along a dark (unlit) path for part of my commute, but the light has been fine for that. My problem is with the very poor quality of the bracket for attaching the light to the handlebars. The bracket was surprisingly difficult to attach and I couldn't get it tight enough to keep it from shifting during my ride.
I've been using the Planet Bike Blaze LED for a while now and I am truly amazed at the amount of illumination this little guy is capable of.I use it on an unlit bike path on my commute home from work which would be impossible without this light. I literally cannot see my hand in front of my face without it, its pitch dark out there.
This is the brightest self-contained headlight I've ever used on a bike. To get brighter you have to pay a lot more money and deal with external batteries and/or more weight, or use a dynamo. It's fine for seeing the road directly ahead at night when in steady-high mode (steady-low mode is good enough if your eyes have dark-adapted in an area without street lights), and amazing for being seen even during the day in flash mode.
The mounting system had some hic-ups that I worked out but once that was complete I went for a quick 10mile jaunt in the rain at night and it worked like a CHAMP. Didn't loosen over bumps and stuttering roadways, didn't short out in the 45mins driving rain, had enough 'uummpph' to light up the wet road and road signs.Good stuff for a decent price.
I bought this light after reading these reviews thinking it would be bright enough to use to light up an unlit trail at night for my commute. Well it is a little brighter than the $15 LED light I had but not by much. It is a great "be seen" flasher light but is not nearly enough for what I need. This light only illuminated a small spot in front of me.
It's too bad this particular light has been discontinued, but it is quite a bit bulkier and actually uses 4x AA batteries instead, which is a bit cumbersome. At least the mounting brackets are similar enough that you can use either light in a pinch.Perhaps doubling up with a similar flood-style light might be the way to go for completely unlit paths at night.
I wanted the most amount of light for the least amount of money. This seems to fit that requirement. I am an occasional night rider with those rides being mostly on the trails and some residential streets. This light is best for being seen, not necessarily for lighting up the path. If I were to do more night riding I would upgrade to light rated by lumens with a helmet mount.Mounted easily to my handle bars and unclips for easy use as a flashlight.
As far as I've seen this is one of the brightest lights on the road. There really doesn't seem to be a need to pay more money for an ultra bright light when this one does a perfectly fine job. It lights up the street signs all the way down the road, and people notice me coming for sure.
This is my second Blaze (My first one was stolen when someone "borrowed" my bike right out of my garage). Battery life seems good. I used it on a night bike ride/camping trip on a completely dark bike path. My headlight was the brightest in our group so I usually stayed up front.
I have owned both the 1W and 2W versions of this light (my 1W version got stolen) and I must say I prefer this brighter version. It is not up to snuff for mountain biking at night, but good solution of nighttime street biking. Only complaint is doesn't stay perfectly on the handle bars - tends to very slowly slip down (over a period of days).
Answer: yes
