Is that normal that I cannot see(even in dark) the beam of LCC that is running at 350mA? If not, then should I run it on higher mA or what?

i have one running @ 380mA and can see the beam clearly in the dark,
well mines an LOC but the LOC and LCC have almost identical characteristics.

Burn some incense in the room

Peace,

Are you sure the diodes not fried? Can you burn things with it, when focused? It should smoke dark, or black objects very well at 380mA.
Maybe your eyes are just not very susceptible to that end of the spectrum?

Even without incense shouldn't the beam be visible in the dark? I can see the beam on my PHR set to 90ma in the dark...

@rpaloalto, 'pwNd' has his laser set to 350mA, i have mine set at 380mA..
just so you dont get confused.

Yes, it can burn easily, much better than my phr@120mA, but maybe I should increase the mA? What is highest safe mA for a 16x diode? And, Stuart can you see the beam from all angles? Like some 10 mW green?

yes.. i can see the beam very clearly in the air even from a side on view without smoke/fog. My laser measures 210mW on 'Morgans' laserbee I, perhaps you should get a respected member of the forum to do a quick power check on your laser, that may be able to shed some light on the subject. also 210mW of red would be much brighter than 10mW of green even though green is brighter to the eye.

I have a loc @350ma and at night I can eaily see the beam without smoke or anything.
So I don't think its the ma even if that is an option.

Keep it at 350mA to be safe.

But you can't see the beam? Are you sure it's not an IR diode?

@pwNd what diode is this, out of a 16x dvd burner or out of the 6x GGW-H2OL blu-ray sled?

i had one running at 380mA and im sure that daguin still has one runnning at 500mA :bowdown: so there's no need to keep it that low, i would sit it at 420mA, im going to bump up mine soon :evil:

yep u definately should be able to see the beam at 350ma, when my DDL driver for my red was stuffing up and only putting out about 300ma i could see the beam

My experience with one of my new LOC from LPC815, Aixiz w/ acrylic lens, LM317 driver circuit putting out 370mA.

Beam is visible in a semi-lit room (lights off, blinds open)
Focused, it energetically draws smoke out of black objects
burns a hole in the dark cover of a matchbook in about 1-2 seconds

Its 16x diode powered by 3x rechargable AAA(900 mah) and lava flex drive v5. I used homemade dummyload of 4x1N4007 and 1 ohm resistor to measure 350 mA...

350mA is quite high for 16x diodes.

am i right in saying that these are supposed to be run at about 300mA max?

try to take a few photos of everything including the driver.

What is the diameter of your beam? It should be around 1-3mm. If it is focused with a "fat" beam you wont be able to see it as easily. Try blowing a match out close to the beam and let the beam go through the smoke. If it has a really thick beam try focusing it down a little.

Everyone's eyes are a little bit different, maybe your eyes just aren't as sensitive to red light as others??
