    I think your black light may have more blue than is good. White should be Ariel white when under a black light. So if thst is the case yes it can interrupt sleep

    So at dusk/darkness when my blacklight is on white surfaces glow blueish. Is that going to have an effect on my melatonin?
    Or is the Watt number to high? I have 25W. The glow of the bulb is purple so must be the right kind of bulb I hope.
    Right now I use blueblockers but question is, do the blueish glow has an effect on melanopsin in the skin?

    dusk/darkness is from sunlight
    ------
    Practically black light can be on 24/7
    There is a picture in @Jack Kruse blog
    with black light is in his daughter bedroom.

    I tried during sleep.
    It bothered me.
    So I shut my black lights when going to bed.

    ...........

    Also
    the picture above in my previous post
    shows that the black light in the restaurant was shining directly and indirectly.

    I am new to this forum, But I thought I would add to this, as I have been researching this lately and would like to make it simpler for some new people.
    So the overall problem with "LED's" is that when they run on "AC" current, it causes them to flicker from the way AC current runs through a normal US house. This AC current will pulse as it is used. In order to get around this issue, you can use LED's that run directly from "DC" current. Because this is a direct line of current and does not pulse like AC current does. This can be easily tested using your smart phone on video record, setting it to "slow motion" mode you are able to see the LED light pulse on AC current. Now, if you start looking around there are actually AC to DC wall adapters for running off a standard US home power supply. What I have found is on amazon you can find a UV 12v Led flood light, that is 10w. this can then be ran off an AC-DC power supply. And by doing this it has a perfect, constant light output with no flickering.
    There are also easier to test devices that are 5v DC UV light bars, that come with there own wall adapter. I have also found a red light LED that uses this same 5v DC adapter method. I will provide links below to all the devices, I hope this helps someone out :)
