After being off for a long time, I was looking into getting another laser but I'd like to figure out how bright a 445 will be to say, a 532. The calculator here isn't up anymore though. Is there anything similar?

This is kind of a generic post, and you seem like you have a good Idea of whats going on, but just remember to use eye protection when you get to the more powerful lasers.

That's a lot of posts. Thank you for everything you have done to hole this forum.

Its not this one, but the solar eclipse on 2024 will pass directly over my house. The exact center of the path is only a a mile away!

Ok, so lets say that heat is not a factor. What, besides heat, limits a laser or any other electronic item for that matter?

But if you had an impossibly good heatsink, wouldn't they not melt?

Lets say you had a diode mounted to a heatsink that was 100% efficient in removing excess heat from the diode. What else limits the amount of current that you put through?

I have a 75 watt weller that my dad got 15+ years ago and it works great still.

Yeah, I figured that. I was just wondering what power it would be around.

It is about the size of the match head, which I was unable to light.

I cant focus it, but ill try it and record it. I'm guessing you would use the video for the time it took to light correct?

So a few weeks ago I ordered one of those ebay "5 mW" 405's knowing that it would be overpowered, but what I got is more than I expected. I dont have a LPM, but how many mw's do you think it is if I can see the beam in my room with the lights on? It would have to be at least 100+mW right?

Your instructable got featured! It was sent to me in the instructables email.

Obviously you cant throw it around at walls and stuff, but how "shock proof" are red diodes?

To the people saying to use red and violet, or any other color for that matter, wouldn't they require different voltages? or do they make violet modules that run at the same voltage as reds?
