    Perfect is only sunlight.
    Actually, perfect is sunlight that reaches us when it went thru (perfect atmosphere).
    In some places on earth atmosphere is already degraded.

    I guess that's the next thing I have to research; Atmosphere..
     

  3. Some helpful information:

    Those who own UVB dependent reptile and do good research will only use Zoo Med ReptiSun tube lights. The T5 lights are the most powerful, and need to be replaced after a year. Acadia is another good brand for a tube UVB light. The bulbs are considered junk. They only put out UBV for about 6 months, and the quality is poor.

    So, the bulbs (exo-terra and maybe osram vitalux?) have a different spectrum after 6 months?

    Do you have a spectrum of the tubes?
     
  5. My knowledge comes from being in the bearded dragon community, and thus isnt super exact and scientific, but is still relevent. Those who have measured found the UVB gone after 6 months with bulbs and 1 year with tubes. Its actually recommended you replace after 5 months for bulbs and 11 months for tubes just to be safe because UVB is so important for a bearded dragons health (who would have guessed?). People who use the bulbs and/or dont follow the guidelines for new bulbs frequently end up with unhealthy dragons who are not absorbing calcium -- they end up with dragon osteoporosis essentially.
     
  6. Also, they are by no means a full, natural spectrum. They are indoor lights after all. I'm just speaking on the UVB rays -- sun is still and always your best option.

    Yes.. I'll replace my bulb, or check out the tubes, to be sure it has UVB. I think I knew this before, but I just forgot. Thanks. And yes, the lights are no replacement for the sun.

    I don't protect my eyes in sunlight, but do I need to protect my eyes when using exo terra solar glo? I know it's got just a little bit of UV, but I'm asking because of the differences between the sun and lightbulbs (the spikes for instance).

    I'm basically using it all the time when indoors. I'm asking just to be sure.

    You need to update your avatar mjau. If you continue to skate the rules you won't be here long.

    Since 40-60% of RBC cycle through the retinal blood vessels when they are exposed to light this shows you how devasting a blue screen is to your brain behind your retina. It not only ruins the circadian cycles of your blood cells it ruins the grey matter of your brain which have more mitochondria than any other part of the brain. Imagine that.

    Yet another confirmation of how time in front of screens and blue light emitting RF/microwaves can have organic and functional impacts on the brain via melanopsin dysfunction.https://www.psychologytoday.com/us/...atters-too-much-screen-time-damages-the-brain

    BLUE LIGHT IS A STIMULANT THAT CREATES ROS/RNS NORMALLY

    And stimulants are great. Most Americans drink a few cups of stimulants each morning ☕️ to get themselves up to face the daily grind.

    But you know what's not great? Being stimulated 24 hours of every day by blue light. This ruins the dose response curve of the ROS/RNS. That is exactly what is occuring to modern humans because they live indoors and use tech screens to an excess. What else is different about this version of blue light? The blue light that wakes us up in the sun is NEVER present without 42% IR-A light which is red light. AM sunlight has 42% red light in it and only 1600K of blue light. This small stimulus of blue light is about to improve executive function of the prefrontal cortex. This blue light needs red light to control the oxidation ROS/RNS that blue light makes when it is present without red light in our light environment.

    ALL CELLS contain ion channels in their outer (plasma) and inner (organelle) membranes. Ion channels, similar to other proteins, are targets of oxidative impact, which modulates ion fluxes across membranes. Subsequently, these ion currents affect electrical excitability, such as action potential discharge (in neurons, muscle, and receptor cells), alteration of the membrane resting potential, synaptic transmission, hormone secretion, muscle contraction or coordination of the cell cycle.

    An important class of ion channels is the family of potassium (K+) channels, they are not only in charge of the membrane resting potential or the repolarization of the action potentials, but also control cell proliferation or transmitter/hormone release, to name a few. A subgroup of K+ channels are the so called calcium (Ca2+) activated K+ channels which need either an increase of Ca2+ at their intracellular face to open or a combination of Ca2+ and voltage to function properly. Maxi Ca2+ activated K+ channels, also named BK channels which constitute a subgroup of Ca2+ activated K+ channels.

    DO you know where these ion channels exist in humans? They are found on the inner mitochondrial membrane. EXCESSIVE BLUE LIGHT exposure destroys these potassium ion channels to ruin signaling of cells that control the circadian mechanism and are associated with leptin and melanopsin. LET THAT SINK IN.

    Mitochondria are a major source of ROS generation targeting BK channels. Blue light creates that stimulus when RED LIGHT IS ABSENT.

    The inner membrane of mitochondria contains BK channels (mtBK) which appear essential in the production of ROS. mtBK channels appear to be inserted into the mitochondrial membrane with the toxin binding sites for charybdotoxin and iberiotoxin exposed to the mitochondrial intermembrane space. This can be accessed by using outside-out patch configuration of the inner mitochondrial membrane. Consequently the C-terminal tail domain including the Ca2+ binding site is localized to the mitochondrial matrix where the proton gradient exists. RED LIGHT MOVES PROTONS BEST. Blue light creates the most ROS. Do you understand why subtracting red light from blue creates mitochondrial diseases?

    When you look at your computer screen or phone screen, your brain wakes up. It's alert. Because it hears "It's day time! Time to be focused and do human things!"

    But guess when it's bad to hear that signal?

    The other 14 hours of the day that the Sun wouldn't normally be sending such a signal to the brain.

    We need a break from the stimulus. Otherwise we fry our circuits and get fatigued.

    So take a break from the blue. Stop the intravenous coffee to your SCN and allow yourself to relax.

    This is why I Chillax, with Ra Optics blue blockers when I face when red light is removed from the blue light stimulus. The discount code is OPTIMAL.
