The light spun_20181114_190803

I had to bail when doing side hops down the stairs, the bars slammed on the ground, the light spun on impact.

I have posted on Instagram about this hopefully Exposure will fix this, they liked my post.

The bike was laying in the stairs, drive side down, but I rolled it to a flat area, and centred the light & tightened the bolt.
So far I don’t think this is a big deal. but under trail riding with no crashes it stays in place, but I time will tell.

Nice cover keeps the input clean, very tight to get on. but in some instances I managed to get it loose, it might be due to me hitting it with my knee or something getting caught in it, because my knee hits the handlebar, the fork crown, the stem, I think it’s most likely because I hit it with my knee. but with no crashes it never came opened up.

Exposure lights bar mount

The red thing under the mount is the quick release pull lever, which works great, it makes removal and install of the light easy, nice when you want to take the light with you or just take it off.

after the winter ended I noticed the pin was out to the right, but I fixed this easily.

The mounting clamp works for up to 35mm handle bar diameter, for 31.8mm there are two plastic half spacers for top and bottom, you can use the thin spacer with the plastic spacers for smaller diameters, for 35mm there is a thin rubber band is secured with a 4 mm Hex bolt.

Even the packaging is great, comes in a nice case , it’s light weight. there are of course more extreme options, but those require huge battery packs, cooling fans: https://kit.com/mtbboy1993/extreme-bike-lights but exposure lights stay cool, they don’t overheat as easily, some lights will overheat in minutes, but Exposure can run for the whole ride without overheating, they stay cold most of the time, only noticed very slight heat from six pack once, I mean barely, which went away quick. so great performance. I rode in low plus and subzero to -5 or 6 I think.
my old Gemini Xera overheated in few minutes in -10C, basically useless light for mtb. at full strength indoors in room temperature when being still the light actually gets very warm, but during riding in the winter it never gets warm.

Other review: I won’t do any light strength/distance tests as this has already been tested by others. videos won’t do it justice, but in 2018 & 2019 I have used these lights, and have several videos with them in use, but as I said video does not do it justice, it does not show well how wide the spread is and how good the light lights up the trail, but you can see from the videos that it’s great, but not how great.

here are some videos anyway:

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.

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.
