    What we did in 2017

    • Started making independent field monitor panels measurements, 5 monitors measured, more to follow
    • Started measuring AC consumption, measurement of NP batteries powered DC consumption coming later
    • Started measuring light luminous emittance, flicker, you'll find first results in reviews soon.
    • Measuring led lights spectrum for more than 25 lights, CRI and such, results links can be seen in this topic
    • We started measuring detailed temperature readings of led lights they can cause degradation and show quality, both contact and IR way.
    • Make sure to check lot of reviews at https://www.youtube.com/channel/UC-Pj7yx6F1TdNJ36eRlZgcA?sub_confirmation=1

    Why we ask you for support

    • We need your support to get some testing equipment.
      • We are collecting funds for lab grade spectrometer now
    • We need your support to form small review fund to get non expensive items for tests, get and test them on members request and sell.
    • If you have some gear and want us to make review, you can contact me by PM.
    • Let us know the gear and specific tests you want to see, you can post in this same topic

    Remember

    • PV does not have ads, "sponsors" or any such crap injecting stuff. We are here for you, not for ads.
    • We even do not have auto playing video ads what became trend in last few months. :-)
    • Each month we pay for dedicated server hosting and it this sum is not small, and additional daily backup located outside of hoster network (for safety).
    • We don't have big team to support site. No admins, paid moderators, etc. All this time is invested in keeping this community alive.
    • Remember to support regularly, even with very small amounts, if you are in economic trouble.

    Where we are going:

    • We are making gear reviews and slowly improving in it
    • We are improving our deals and will add new partners
    • We'll also have some software updates focusing on new features and becoming more tablet and mobile friendly - work is being done in this regard, moving slowly.
    • We have new video contests coming - working on this with few manufacturers.
    • Stay tuned.

    We need your help, remember to donate using orange Donate button above this page!

    Thanks in advance.

    Done. Thanks for your job

    @davjd

    Thanks.

    We have 18 donations now, at around $250.

    Almost reached first goal.

    Note that paypal fees plus their currency conversion also take not small cut - around 6-7% total.

  • Vitaliy_KiselevVitaliy_Kiselev

    Thanks to Andy donation we also reached second goal.

    So all donations now go to spectrometer.

    What kind of spectrometer we want to get and why?

    Min approach

    • General spectrometer, used most probably
    • 3.5nm-10nm resolution (first is high res noisy mode)
    • IR is cut by filter, models without UV cut exist, but not sure if filter is absent in ambient mode.

    Max approach

    • Pro level, 3648 pixels spectrometer for high resolution, may be settle on cheaper 2048 one
    • 3nm and below resolution
    • We want to be see part of IR and UV spectrum, not visible part only

    Spectrometer allow to measure spectrum for many purposes, for example:

    • led and fluo lights spectrum allows you to say about their quality
    • measurement of filter transmission spectrum allows you to say about IR contamination and color shifts
    • you can do also transmission measurements with lenses
    • measurement of monitor primaries spectrums is also useful

    I started lights FAQ section

    http://www.personal-view.com/faqs/laboratory/measuring-lights-faq

    As we'll have reviews up and such I'll add PV specific parts and more useful info.

  • matt_gh2matt_gh2

    This is very good. Thank you.

  • Vitaliy_KiselevVitaliy_Kiselev

    We have 22 donations, $10 now (after transfer for two first goals - $280 + $50).

    Thanks to all who helped.

    Remember, if you are in EU and want us to test something (like your light or monitor) you are welcome.

  • Vitaliy_KiselevVitaliy_Kiselev

    Next PV Lab reports - considering monitors delay (lag)

    Let me know if you have any suggestion.

  • Vitaliy_KiselevVitaliy_Kiselev

    We have 23 donations, $25 now (with reduction of two first goals items).

    Thanks to all who already helped or just have intention to do so soon.

    Added more stuff at http://www.personal-view.com/faqs/laboratory/measuring-lights-faq

    Remember to keep supporting us, as spectrometer is one of the main lab tools.

  • Vitaliy_KiselevVitaliy_Kiselev

    We have 26 donations, $70 now.

    Thanks to all who already helped or just have intention to do so soon.

    Two first goals items bough and on the way to us. I'll post photos as we'll get them.

    You can also check short take about lux meters

    just sent some stamina. the hours we've spent (& the ones we will spend) here, avoiding expenses for beers, really worth everyone's donation.

    Thank you for everything VK. Donated =)

    I am now getting last parcels for Russian lab. Soon will be getting some new equipment for precise monitors panels performance testing and high frequency PWM modulation testing.

    Soon will write more detailed separate post about spectrometer and it's usage in testing.

    We still need your support to reach our spectrometer goal!
