Twin 445s from Flaminpyro

If all you want is burning videos I have plenty just check my youtube channel

I'd like to thank Flaminpyro for my two new favorite lasers. He's a great guy to deal with. Alright on too the lasers.


I got four lasers in two days


The pictures don't do them justice. They're beautiful. I got the hosts from DX DealExtreme: $13.56 UltraFire A10B Cree R2-WC HA-III 5-Mode 250-Lumen LED Flashlight (1*18650) .

I've learned these diodes are very sensitive to temperature. It can effect the output by up to 20mW going from 80 to 70 degrees. Because I live in Texas these are definetly winter lasers.
Specs:
One is set to 650mA putting out 530+mW depending on the temperature.
It's driven by a v5 flex, powered by a single 18650, and uses an aixiz 405 glass lens.
The second is set to 875mA putting out 780+mW. Hit a peak of 805mw on a low battery at lower temperature. It uses the same stuff as the other obviously. They're twins .

Burning:
These make awesome burners up close. 530mw of 445 will easily match 450mw of 405 at a short distance, but over half a meter, and the 8x will win at a burning contest because of the bar output.

Brightness, and color:
Both 445s in the night sky on a very clear night. The color seems almost perfect to me. Deep blue with a slight tint of purple.


800mw 445, 450mw 405, 200mw 655, and 500mw of 445.


Added 20mw of green.

Congratulations on the twins... you must be so proud :crackup:

Seriously though... looks good hope you have a good set of glasses

Lol I can't even see the spot when they're unfocused.

Ever ran them for short time, remove the focusing lens, and take a temp check? I wanted to know whats a safe range to run diodes in terms of Fahrenheit!

Otherwise I agree, I love knurled surfaces!

I'll try it. My girlfriend got me one of those nifty IR thermometers . Although the spot being measured may be to big to get just the diode I should be able to get a reading inside the module. Check back in a 5 minutes for an edit.

EDIT: Nope, sorry I let the host get to about 90 degrees but I couldn't get a reading inside the module.

Thanks for the very kind words I do try to provide the very best there is

Hmm, wasnt possible just to jam the ir reader into the aixiz module I take it? I would think our modules are the same, but I don't know what a safe temperature range to run a diode is. I had times where I was using it for extended periods, on and off many times for short runs...I got it to about 92F (The heatsink/diode was equal temp) and I put it aside because I wasn't sure if that was good for the diode to be running at this temperature!

I know lots about electronics, but I know nothing about Laser diodes with heat. All I know is heat can effect the wavelength...

Yeah, I was kinda wondering the same thing. I never let any of my lasers get much over 90 degrees just to be careful. Can't wait for winter to come now . Longer duty cycles, and MORE POWER! these diodes love to be cold. As for wavelength change I think the colder they are the shorter the wavelength.

lol i like how your green is the least bright

Has any one put them in the ice box yet

hmmmm...^^ maybe if its waterproof lol the moisture would get into the lens and diode and ...... just no one try it ok!

This thread is kinda old... I think he sold them a while back.

Dont bump old threads, unless you have useful information to add. Otherwise we'll dump your rep.

here is some useful info--I just got the 'twins' from Kevin-still making the same mWs and Kevin gets a +2 from me for the great deal and the extra free goodies!!! like a 70mW WL 532== dang Kevin--!!!! WTH ??
FP does nice work-- copper HSs rule-- thanks to both of youse guys!!

lol

^These are Nice. Yes FP does makes some Killer Good Lasers.

These are some High Quality Hosts for sure. The anodizing on them is amazing.

Nice Buy.

Thanks Hak for the kind words, I do try my hardest to put out only the BEST
