yes. There is science and anybody with normal intelligence can understand it. Not you but anybody wit h normal intelligence.
Look it up. Specific brightness is a physical quantity and completely measurable.
Some LED bulbs can damage your vision.
Just stop with the ignorant babble.

About what? Brightness? It's not an SI unit of measure. It's a perception. It's ambiguous. This is science not pulling whatever out of your ass, spewing it, thinking it is fact.

You forgot the citation. Just more shit. Does your ass ever get jealous of the shit that comes out of your mouth?

What you said:
Goddamit you are stupid. I said some LEDs can damage your eyes. Here is one citation:
https://www.ledgrowlightsdepot.com/blogs/blog/7-common-led-grow-light-myths
(myth) 6. Light emitted by LEDs are harmful to our eyes
There is a myth that LED lights harm our eyes and even can cause blindness. Of course, if you stare directly at a LED bulb for hours, they, just as any other artificial light source, will be harmful to your eyes. But if you use LEDs normally, they are completely safe. CELMA (Federation of National Manufacturers Associations for Luminaires and Electrotechnical components in the European Union) have released a paper stating that LED products are strictly designed to meet all photo-biological safety standards, meaning that LED lights, including LED grow lights, won’t cause blindness or any other harm to your eyes as long as you use them as intended.
Don't fucking stare into a bright light.
Idiot.
That pain and bright spot that remains after staring at it? It's your body is trying to tell you to not do that.

Bulb?? WTF is an LED bulb? I said LIGHT bulb.
Bullshit. Show me.
I said light bulb.
I'm the idiot? (myth) 6. Light emitted by LEDs are harmful to our eyes
Let me be a little clearer. Citations from a reliable source.
Reliable sources may be published materials with a reliable publication process, authors who are regarded as authoritative in relation to the subject, or both. These qualifications should be demonstrable to other people.
Someone selling shit does not count.
But regarding LEDs OSRAM has this disclaimer in every horticulture LED datasheet:
The evaluation of eye safety occurs according to the
standard IEC 62471:2008 ("photobiological safety of
lamps and lamp systems"). Within the risk grouping
system of this CIE standard, the LED specified in this
data sheet fall into the class Moderate risk (exposure
time 0.25 s). Under real circumstances (for exposure
time, eye pupils, observation distance), it is assumed
that no endangerment to the eye exists from these
devices. As a matter of principle, however, it should
be mentioned that intense light sources have a high
secondary exposure potential due to their blinding
effect. As is also true when viewing other bright light
sources (e.g. headlights), temporary reduction in
visual acuity and afterimages can occur, leading to
irritation, annoyance, visual impairment, and even
accidents, depending on the situation

If you keep talking do you think someday you may say something intelligent?
