Question: Where can I buy spare rubber bands for this light? Very easy to loose the bands. Is there a more reliable mounting method?
Document: To have this much power for this price is unbelievable. It rivals lights costing hundreds more. After a recent evening bike ride I was driving home on a rural road and turned off the headlights of my car and held this one out the window. Although it was a little dimmer than my headlights, I hardly noticed the difference. The screw did come loose holding the light to the base but I was easily able to tighten it. The heavy duty rubber bands that strap it to my handlebar work great.
Great light with a price that can't be beat. At this price it could be a throw away light after one &#34;season&#34; of mountain bike night riding. Have had a very similar light for two years and expect this to go the distance as well. The simplistic mounting ring makes it easy to mount on handle bars of various diameter.Battery lasted 90 minutes on first time out with only 1 hour of charge time (from time of receiving).
Even though it took a long time to charge the battery, I still like this light. It is very bright and easy to install.
So, the light is nice and bright... after being mounted on the bike and after miles of commute, the wiring got loose inside the housing of the light and now it doesnt work. So, now I need to take it apart and fix the damn wiring. So, the only reason I gave it an extra star other than 1 star is because its very bright.
Bought this for my daughter to commute with at college. The light is bright with good run times per charge. An important factor for her was the ability to set up and take down quickly, which it does. It takes up very little space in her satchel. I am looking forward to seeing how it does on an extended night run on her mountainbike. The overall quality is good  and I am impressed with the attention to detail. Spare battery packs are available.
This does what it's supposed to,  plenty of light to see the holes and bumps I don't want to ride over when it's dark. A little bright for the walking/bike trail so I aim it down to make it easy on the eyes for the oncoming walkers on the trail. On the road the dim setting is usually plenty and the bright if it's really dark. Thus far it's recharged like it's supposed to and I've never run out of battery life while riding.
So much so, after doing some MTB night riding in Utah last fall I bought two. Reason was to have a spare and secondly to have a greater field of view, as the beam is somewhat narrow. But at this price, why not?
I bought this light so I could garden at night and for general use. It was a good price and quality. The beam is very strong, has a long range and comes with a couple of settings. The rechargeable battery pack lasts a long time. It also came with a head-strap and handlebar mount. The handle bar mount (basically a thick rubber band) is difficult to put on, however. This is why I gave it 4 stars instead of five.
I know that there are other similar items  out there for night bicycle riding but, I don't think you'll find them at the same price as these. 3 light settings from blinding to bright. I bought 3. one for my commuter, one for my mountain bike and one for a spare...they were that affordable. I have no trouble seeing on moonless nights riding my mountain bike in the hills. Comes with a head (helmet) strap and 2 o-ring style clamps for the bars.
Good budget light that will get you through the long cold winter months. Very light weight so it will be easy on the helmet
