1W of 445 looks like ?mw of 532?

[SpaceCase]

How many mW of 532 are comparable brightness to 1W of 445?

How many mW of 532 are comparable brightness to 1W of 445?

I would say 200-250

Not quite that much, its more like 1W 445nm = 99.270mw green, but everyone's eyes are a little different so people perceive it differently.

See here, this was calculated using Chroma taking Rayleigh scattering into the equation. Very interesting read.

I'd agree with udanis; 200-300mW. The brightest green laser I have is about 150mW (on a good day) and it isn't nearly as bright as my 925mW 445nm laser.

Our eyes only perceive 445nm about 30-40% as bright relative to the green light peak. So you can crudly equate them by:

.3 X (mW of 445nm) = (mW of 532nm)

...roughly

my 445 is around 1600ma and it completely overpowers my 90mw green.

What about photopic and scotopic vision?
What about variance in diode wavelength?
What about atmospheric conditions?
Are we talking about the beam or the dot?

This should help you a bit

But as RA_pierce mentioned above, it is impossible to tell without implying especially humidity coefficients.

Glad I came across this thread. I've been wondering about a basis for comparing green and 445 blue.

I really can't wait for the green diodes to come out like the 445nm and 638nm diodes.

uhhh

yes : P
