Very awesome!

[@thevineclimber]

Thanks; very detailed review eill help people decide what to purchase.

[@TheFossilChannel]

thanks anne!

[@javig1011]

In the 170 lumens mode, is it capable of staying on for the 3 hours indicated in the manual or does it drop to 60 lumens shortly so as not to overheat? I need 170 lumens for at least 1 hour.... I have the Nitecore H11 and it lowers the intensity shortly after turning on. thank you

[@goncaloserra2051]

Very nice review. Can I ask you what is the name of the app that you use on your smartphone for photometry? Thank you

[@TheFossilChannel]

Thanks. Its the oppel light master pro app. You need the item to transmit data to the phone.

[@goncaloserra2051]

@@TheFossilChannel Thank you so much for the information.

my friend vanquest edcm slim bag arrived, i feel really good quality but it is too big for me to carry on my waist so i will carry it on my bag.

[@TheFossilChannel]

Okay, thanks for the update

[@Tao_313]

Fossil, what was comfort level? Also, charge time, on say a battery bank? Like 25% to 100% ? Standard, not QC?
Great review!!!!

[@TheFossilChannel]

I like the shock cord beter as i sweat alot and it doesnt feel as bad. Depends on a battery bank current transfer say .270mah vs a bank that can do 100mah. Usually about an hour or so. Sometimes more depending on how far the battery is gone.

[@Tao_313]

@@TheFossilChannel I figured, went as vague as possible on charging in the field. Thanks!
Nice review! Be well!

[@TheFossilChannel]

Thanks tao. The capacity of the internal li-ion battery is around 500mah. So the charging rate of around .300mah is quite alot. If its charged in a 50-70f temperature environment it could be as little as an hour or less.

[@Tao_313]

@@TheFossilChannelExactly what I was looking for! Thanks!

[@SurvivalSavvvy]

I picked up the Nitecore NU43 which is crazy bright but this is lighter with alot less lumens.

[@TheFossilChannel]

It may be the settings im shooting at with my gh6. Also wavelengths of different colours can appear brighter. My eyes react well with tungsten or warmer colour lights with rosy tints. For reference I am shooting at f2.8 with an Iso of 10,000 and a shutter speed at 1/48th speed with a frame rate of 24.00 with a white balance of 5000k. I lock in the settings so nothing changes and the light doesnt force the iso to change or aperture etc..

[@TheFossilChannel]

The nu43 looks like a power house too. How do you like it so far?

[@SurvivalSavvvy]

@@TheFossilChannel Its not enough light. hahaahah.... Camera like light the more the better.

[@SurvivalSavvvy]

@@TheFossilChannel Super power, very nice when setting up a big tent. Also great for video. :) I like the USB charge with a battery inside where most do not like that. I have been upgrading all my gear to not carry extra batters. My cameras are the only thing I have with extra batteries now. Where everything else just plug the USB into a batery pack when I goto to bed.

[@TheFossilChannel]

The benefit of a system is that is very streamlined and fast charging.
