    Lume - avoiding disappointment

    On the forum, many people have a tendency to criticise lume of the watch. So I Googled the topic and here is what I found.
    https://......./images/UYWpcA
    The test standard for lume brightness is ISO 17514
    https://cloud.tapatalk.com/s/580847af...andard3902.pdf
    The standard mentions that a tested lume has to be applied in certain thickness and be charged under D65 light source anywhere between 20-30 min.
    https://en.m.wikipedia.org/wiki/Illuminant_D65
    200lx for 30 min, 400lx for 20 min.
    Then brightness of the lume is a function of the humidity and temperature as well.
    So the moral of the story is that not all SuperLuminovas are the same. Next time you buy a tool watch, the questions to ask, the thickness of the applied lume and if lume is applied in a controlled room environment or preferably environmental chamber rooms for best results.
    Given how watch companies are very secretive, the best defense is educate oneself.

    When I buy a watch, I check the lume in the dark and maybe review it to see how others have got on. I don't use government standards and a tin hat :)

    Also are you suggesting that all watch companies publish the technical specifications of every single component and construction material, including thickness of lume, degree of dilution based on substrate etc? Do you really think anyone else will care?

    Yea, even the exact same lume applied with different viscosity also will yield different results.

    ^ I am saying, that dial makers request a spec sheet probably from manufacturer. They select lume based on color and brightness data. However, when dials are produced the result which specifically has to do with lume maybe significantly different.

    Here's an updated Super-LumiNova chart for your reference.

    I try to avoid lume disappointment if I can. For me, BGW9 and C1 are just worthless. It's a travesty to call those two, Super-LumiNova and it's misleading. Maybe my eyes can't register it, but it's utter junk to me. I sold off a very nice Deep Blue Master 1000 because its lume was no better than my Casio MDV-106.

    Yes, the performance of lume paint varies by type. And the thickness and application process also has an impact on performance. However I'm not aware of any watch company that provides details on how the lume paint is applied and whether performance meets the standards of the paint manufacturer. For most of us the information will come from online anecdotes. For example my experience has been that the lume paint on many Seiko watches performs very well..

    Another point to remember is that even the best of lume paint will burn like the sun for only a short time. It will steadily fade to the soft glow of a distant star visible only with dark adapted eyes.

    Then they've produced another color since I downloaded this chart in April of this year.

    Please feel free to post the latest Super-LumiNova chart so we can all reference the latest colors.

    Agreed. My Bremont and my Omega have similar hands and similar applied surface areas of Superluminova, but the Omega is pretty good while the Bremont's lume is really, really poor.

    Speaking of which, you also need to take into account the surface area of the lume; my Zenith has these little pips on the hour markers that, while they glow with reasonably good intensity when first charged, they fade more quickly from view than the Omega because there's less actual illumination being put out.

    Of course, the Ball wins hands down, with its tritium tubes. Not as intense as my Omega at full charge, but somewhere between 30-60 minutes, it pulls ahead and never fades.
