    Fantastic video! Thank you for being so clear, concise and articulate. Intelligent man.

    Ebay 3W 365nm LED's produce white light along with UV. There is much less fluorescense than with blacklight tube.

    They should make LEDs at UV-C wavelengths like those 254 nm germicidal fluorescent bulbs.

    Well one difference is 385 is not uv, just a deep violet, normal visible (it appears purple) once it appears white it is just uv.

      365 is much more dangerous and requires more power for semi-florescent than 395/'85. But for legit florescent things 365 is best.

    I have a question.If uv resin is rated at 365nm, would it still cure up to 400nm?Thanks

      @UVBlackLights 4 года назад

      Adam Naperty most likely not as there isn’t much UV coming out of the 400nm. It might work but it’ll take much longer. Everyone cures with 365nm black lights.

    Will 365 lights project a longer distance and make florescent paint glow brighter then 385?

    I would really like to know what 390 and 400 nm looks like and what 690 and 700 nm looks and feels like

    • @ApolloMFGUSA
      @ApolloMFGUSA  7 лет назад +2

      690 to 700nm are at the top end of the spectrum (deep red). At this nm we start transferring in to the non-visible, in this case IR. IR will not cause fluorescence.
      Visually 390-400nm will have more of a purple hue than 385nm as we are moving closer in to the visual spectrum.

    I've been looking for a true black light torch. The supposedly LED black light torches aren't true black light. True black lights don't emit any glow or beam, like the LED torches which emit a pinkish or purplish light or beam. That is in no way an invisible light if you are able to see that colored glow or beam on the ground at night or on darker objects, unless they are reflective.
    With a true black light, e.g. a fluorescent tube, you will only see your teeth, eyeballs and other white objects, but not the glow of the source. You may see the black light fluorescent tube lighted up a little, but no glow surrounting it. You don't call light beamed out in pinkish or purplish color from a torch - a black light, or invisible light, if you can see the light or beam. Invisible means invisible, otherwise it is not invisible. We are being fooled.

      LEDs emit a gaussian spectrum. They're not monochromatic like lasers. A high-powered emitter at an invisible wavelength like 365 nm will also emit a fair amount of energy in the visible spectrum. That's what the dichroic filter is for. It cuts off visible wavelengths almost completely and absorbs only a small amount of UV.
      You won't find a "true black light" or invisible UV source with an LED, fluorescent, or any other light source that emits a band of radiation, unless you operate it at such low power that the visible emission is too weak to see. For that you will need a quantum dot, laser, or some other much more complicated/exotic light source. And even a laser can be not monochromatic enough sometimes.

      Thanks for the info, James. I remember when I was a teenager going to school dances there were some fluorescent tubes that emitted a faint purple light, almost dark colored, but the whites of eyes, teeth, garments, etc., were absolutely white. And if you didn't smile or wore a darker garment you wouldn't know you were around. Also, some jewels and the watches dials and hour hands were also glowing bright.
      Over the years, as dance venues changed or ended (e.g. rock and roll) these tubes eventually disappeared and multicolor flashing lights appeared with the arrival of Disco and other stage craziness. And finding black light tubes were hard and they were expensive to own. Now that we have LED UV light in torches and also in hand held devices used in laboratories and researches, these are not really UV but are designed to be able to produce light in the 365 range, helped with filters, they're made possible to emit enough black light with the help of additional filters. UV Beast is one such torch light that is capable of producing black light as well as additional bluish glow which is good to direct the beam straight at a subject, e.g. a glow stone, a gem or minerals.
