In perfect scotopic conditions 1.4W @ 520nm would be 2225.30 lumens whilst 5W @ 465nm is 5270.00 lumens.
For the record 7W @ 445nm is 4677.89 lumens and 2W @ 532nm is 2655.40 lumens. The problem with this model is most of the time whilst using the lasers, we are not in total darkness and our eyes are not in night vision mode.
If i account for low light conditions instead, the values would change to

2.0W @ 532nm = 2501.83
1.4W @ 520nm = 1845.20
5.0W @ 465nm = 3358.41
7.0W @ 445nm = 2920.04

I would love to own a laserscope, but it is not a viable option for me :cryyy:
It is too big and dangerous to have in my house, and haven't go time to modify it for general use.

As for the brightest handheld, it all depends on the lighting conditions of when you use the laser. A 7W 450nm at least theoretically should be brighter than a 2w 532nm at night, but during indoor lighting conditions they will almost be perceived as the same. Is there anyone that can verify this with their own?

I have to disagree. If we're talking about a beam from a single emitter, 2W of 532nm will be a lot brighter than anything else available. I've seen a 2W labby, and it serous blew everything else I've seen out of the water.

My values were calculated using simple luminous efficacy calculations which I appreciate it could be wrong, who made this calculator?
Thank you. I was so close to getting a 2W 532nm at a bargain price, but the supplier informed me that he had stopped producing them and has gone to 520nm instead.
Does this calculator take into any light levels?

In personal experience, 2W of 532nm still totally beat the 5W 470nm and 7W 445nm I've seen in dark conditions.

The LPF user rhd made this calculator.

I think light levels are accounted for using the dot vs beam selection.

Check XPL out if you still want to get a high power 532nm laser. 520nm isn't bad, but you can get such a nice beam with DPSS. http://laserpointerforums.com/f55/feeler-xpl-lasers-rg-y-rb-m-high-power-532s-etc-97779.html

I actually have a 5watt 470nm, 1.4Watt 520, and a 7 watt 450nm... It's hard to tell which one is brighter though... They are all blinding lol.

Yes a 5w 465nm is brighter than a 1.4W 520nm in dark environments. But in room lighting it would be:

1.4W @ 520nm = 1059.69
5.0W @ 465nm = 1233.90

So there isn't much difference between them. 465nm is a wonderful wavelength to own, even non-laser enthusiasts prefer the 465 to 445nm.

I would definitely have to agree. I can't wait to eventually have one

This is when all lasers are at their brightest, so I would have to assume that you are correct on this one :)

As for the 532, he was going to charge 530 usd, which i now realise that it was a clearance price excluding shipping (where he would make the rest of the money). Thank you for showing me this but I have only just purchased a 473 from styropyro and now am lacking money :(

Yes, brightness experiments really need to be done at low levels because they all just look ridiculously bright at class 4.

You won't regret it, brilliant wavelength at extremely high power. What is not to like.

Oh, forgot about that visibility change at night. Interesting though, as to me a much lower powered green seems as bright as my 1.3 watt 445 at night.

My 470 peaks over 6W and my 520 peaks over 1.5W but their divergence is not the same and I think it's the major factor that throws the which is brighter question out the window. Would be interesting to try them out with their lenses removed though and see how they light up their surroundings. Of course I equip them with 3 elements lenses for better divergence just like almost every laser I own that isn't a single mode. I measure their output for labeling and danger potential with a G2 but then equip them with a lens for beam quality. It only takes seconds to change any of them back to another lens anyways;)

I feel like green is overrated in terms of brightness, I've found that my 800mW 520nm comes close in brightness with a 445nm 2W beam and just as bright as 445nm 3W, and my 465nm 07e just destroys the 520nm diode when it comes to brightness. Maybe my eyes are weird or something lol but I don't find green to be immensely brighter compared to other wavelengths of "lower brightness," sure it's a bit brighter and it is noticeable but when I put my laser specs compared to the 520nm in the brightness calculator and then compare them in reality I find the calculator to be somewhat inaccurate, or maybe it's completely accurate and I'm just interpreting it incorrectly :thinking:

Back when I had a 500mW 532nm it was blinding! I mean it was freaking ridiculous :evil: My 60mW 532nm laserbtb is not blinding to look at, it's bright enough to be easily seen and comfortable on the eyes. As soon as you get into the 150mW-200mW of 532nm light it gets too bright for me :yh:
