What is the wattage equivalent for 1W green laser to blue?

[Starpluck]

I am more interested in a bright, daytime-visible laser over the capacity to burn. I want to get the 3 or 4 watt blue laser (445nm) but am also contemplating a 520nm 1 watt green laser.

What should I purchase? I just want the most bright one.

Hi,
NDB7A75 diode with a driver set to 4A in a 25mm DTR copper module. End of story

Relative Laser Brightness Calculator

Use this calculator to compare laser brightness at different nm and mw

edit: checked for myself out of curiosity and a 1W 520nm will far outshine a 4W 445nm blue

Can you please provide us with your age? Be honest

Just get a 200 -300 mw 520nm. Awesome brightness, awesome beam visibility and awesome beam specs. Plus it won't burn everything it touches like a 6w blue would. It's like people don't realize how bright 300 me of green actually is. You don't need lasers above a watt for it to look impressive

Lol!

go green all the way, wayy better than blue
yellow would be even better, but green will do for now

1w 545nm

Wattage equivalent in what sense? 1 W is equivalent to 1 W, of course. Without telling us what you are asking, the answer is trivial.

1w 545nm

That is frickin amazing!, but I don't consider anything below 570nm to be "yellow"

in the right conditions, 545 does look (kinda) yellow like 20-40% yellow and 60-80% green

Hi, Athough good answers have already been posted to your question,200-300mw 520nm is extremely bright even in daylight, while the 1 watt 520nm green is insanely bright and also considerably more of an eye hazard and there is really no reason to get a 1 watt green for general purpose visibility or pointing since 200-300mw green is easily seen in daylight and much brighter than the blue lasers

Honestly, I feel like my 1w green 520nm is brighter than my 3w blue 445nm in the night sky, green is just so more vibrant.

Hi,If you do the brightness comparison,1 watt green is equal to about 13 watts of blue for basicly the same percieved brightness to our eyes but the blue at 13 watts will be substantially more energy, not to mention very dangerous to the eyes or anything the beam hits

555nm would be brightest in daylight. Most obtainable is 565/545 dpss. I have a 35 mw 575nm and you can see the beam in mid day sun and the dot from a good 300’ away. I suspect it was a high humidity day. It was summer. You don’t need a lot of power near the peak of human sight. What is brightest at night is different than the day.

My 18mw 555nm dpss is very similar, I can see the beam in daylight
