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

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

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

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

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.

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
