2 Winters Review: 2015 Gemini Xera 950 lumens light

I rode with this light at max brightness a lot, and I think 2 hours on max is way too low for me, I have to charge it when I come back or have more batteries with me, If  I want to continue to ride in the dark, but I try to ride as much as I can when in daytime,when it’s bright,but this means riding from 09-16, if need to work on my bike or go to the store, or do other important tasks, I just have to ride in the dark, So a good light is important, so far this light is OK. I of course switch to the weakest mode, when I don’t have to have as bright light, but if you want to ride in complete darkness, for a long time this light is not for you.950 Lumens is quite OK, but I want something brighter with wider and longer reach, but I just bought whatIcould when I could as fast as I could, so the local sports store it was, I t was not cheap.

For me the weakest mode does not blind me, but when riding in the city,o r where cars drive, or near people, keep the light pointing slightly down,b ut, Even so, I have had complaints from people so far way I could not even see them, said the light was way too bright and they  were blinded, this was surprising, but some other people I don’t react to it and think it’s fine.

On Mavic Notch
2 Cell battery pack
4 Cell battery pack

 

Battery life:

after 2 season the battery died.

Pros:

  • the light on the button changes colour from green to yellow to red, when the battery is low
  • can be used as a headlight
  • Secure rubber ring mounting, no issues with slipping.
  • can be mounted to most XC and road helmets
  • replacement glass provided.
  • Velcro straps work well.
  • comes in a nice box, to store the light in.
  • i had no issues with fogging glass the light not working in wet conditions, it worked well no matter the weather, I have been riding in -10 Celsius, or summer-Autumn rainy days, I had no issues what so ever.

Cons:

  • short battery time on max brightness, with the stock 2 cell battery, I ordered 4 cell battery pack.
  • the provided strap is too long for many of mountainside top tube,s which makes the battery slide.
  • The cable plugs disconnects while riding in in green& blue trails, rock gardens will unplug it for sure, this happens no matter if i mount it to the top tube or on the stem spacers.
  • Gets as hot as a heating radiator, even when riding in below -10 Celsius, but new version , got a different cooling fin design, but I have never tried it out.
  • would be nice with a 3m adhesive mount or go pro adaptor for mounting to a full face helmet

LED Lenser T7 no.7439 light & Bracket/mount review

its not a bike specific light but,i need a decent light for commuting, but its a horrible choice if you use it at max power for long distances after few days you need new batteries, So I can’t recomend this light for mountain biking.

so i got my self LED Lenser M7 LED  (Item no. 7439) flashlight,

i got a clamp too it fits thick bars and comes with rubber spacers os it can fit on thinner handlebars.

its not a cheap light but the good light are often expensive.

if you crash or get off the pedal and hit the light you will push the light out or almost out of the clamp,but during rides it does not slide out.

pros:

  • light light adjustment
  • made of metal so its strong,but its heavier than plastic lights of course
  • nice button on the back with nice feel,and click.
  • pattern for extra grip
  • good battery cartridge, you cant get the batteries or cartridge stuck inside the light.

cons

  • Last about 6 Hours  with energizer max power batteries, after 6 hours it is getting too weak to ride with
  • lights up way too small area,its useless for riding fast in dark woods or paths/trails.
  • it should be water proof but i got damp inside on the inside behind the glass,but i have ridden in some really bad rain.

Bracket item No. 7799-PT

pros:

  • tool less easy to mount the clamp/mount
  • easy to take off the clamp/mount
  • clamp got turning joint so you can’t adjust the light for the right angle

cons:

  • after more than 1 season the light began to slip forward when riding hard, but that can be fixed with some rubber or tape.

 

Verdict:

This is a ok flash light, but not a bike light, way too narrow and short beam.

Buy a proper bike light.
