How bright is a laser compared to a XM-L?

Ultrafire P60 XM-L at 3.2 amps and 445nm 1.2w laser pointer.

Interesting comparison, I thought an XM-L would look brighter.

What were you searching bro? That’s a very old post of mine. :smiley:

I wonder when are we going to see the laser flashlight technology be implemented like BMW was doing it with the concept cars, have any of you seen it yet?

IIRC it was a blue laser pointed at a phosphor film that produced blindingly white light after being exited by the laser. I’ll see if I can find the link… Here it is!

I can envision that pointed at a small 1 or 2 mm phosphor circle or sphere inside a big reflector, humongous lumen output!

So Chinese vendors can you copy (I mean borrow :wink: )that technology PLEASE!!!

I know :smiley:
I was searching something like this but with better build quality, it’s a P60 with a laser, but since it’s plastic it isn’t much useful for XM-L

But then the only result I found was this, and I like the comparison very much so I bumped the post so other people can see it (also, personally I think that when somebody shares something it’s nice to see others comments)

AlexGT, that’s interesting. Never come across that before.

Here is a video of the laser headlight in action

That’s probably a 405nm laser. So it’s like your regular fluorescent light (also converting UV to white light), just that in this case it’s more focusable/directional.

Few days ago a friend took my laser and started pointing at me. Got my DRY out of my pocket and flashed him for a second in turbo mode, he saw black spots for the rest of the night :d.

That’s a very bad idea. What pointer did he use? Some high power 445nm blues have hazard distances of over 300m. (0.3 seconds exp, blink reflex)

eh, you get used to the royal blue spots after a while……

Really, lasers and eyeballs. big no no

Green 5mw laser from DX. He was shining on my torso, I don’t think he’s that stupid :d. 2500 lumen is an incredible non lethal weapon at night :d

Ok, that’s cool. I have the X100 on hand already….gonna measure it soon. But I want to watch the Olympics as well….think have track n field already?

Would a Laser like that 1.2w burn skin? I’ve watched a wicked lasers video where they burst a load of balloons with it.

Yep it’d burn skin fast. Don’t try it, due to blue light hazard (carcinoma etc).

At what distance would it be effective?

Nice video

So would blue or green laser be the most powerful for any given wattage?

It depends. Green has a noticeably lower divergence even for the higher powered greenies. They’d be better slightly longer distance burning.

Blue is the most powerful but it’s a multimode laser and the beam quality is not so good, it diverges more + does not have a dot beam so power density is not as good. But when focused to nearer distances like less than 6 feet, nothing can touch it due to the availability of higher power. And also due to the better value for $$$ in terms of wattage per dollar.

I am not good at explaining things and not really an expert, you need to read up on laserpointerforums for all the technical stuff + safety.

Ok, thanks for the info, i’ll have a read up on them.
