Yes it is. I have no idea where you read that people were limiting this diode to 150mA. I limit mine to 300mA. They burn very well and last forever that way as long as yoiu don't overheat them. Some people are recommending that you limit the PHR-803T diode to 150mA, but that is a blu-ray diode NOT red.

Peace,

Thanks for the information.

I cannot post links, but (just as example) people at "laser community" say 100-150mA...
Of course I trust you more

Default Re: blue ray and 16x dvd lasers help

my question still stands,does a 200mW red made from a 16x DVD diode burn more than a 140mW 803T blue ray? Thanks for all your help

different surfaces burn different with those two a bluray will toast your hand at 60mw focused but a red at 150mw is barely felt *:

a bluray will smoke white paper at 100-150mw my Rpl green at 450 mw will not ??/ again depends on the material and wavelength.........................

Default Re: blue ray and 16x dvd lasers help

just found the sony dvd burner diode data sheet directly from stonetek...
it says 150-170mA operating current...

NOW I'm confused...

If I harvest a diode from a dvd burner (like my old NEC that may be used for this)
how do I find out how far I can go with the current for the diode without burning it?

You can't. But then again, the datasheet has the specs that it can be run at for optimal use+long lifetime...
people run them at over 300mA all the time.

rckstr is actually a really good driver.....
i've never use any other drivers than the rckstr though, but it still fits inside the aixiz module...

you need atleast 7.2v for the red laser.
mw depends on the diode you buy.

the diode from stonetek can run on 300ma
i have mine going at 350mA, but i think thats pushing it.

Default Re: blue ray and 16x dvd lasers help

I see... 150mA is the regular "wuzz" current for burner diodes
and 300mA is the current LPF users run burner diodes on 8-)

So 300mA should be ok (with an eye on the temperature) with
any harvested burner diode?

Yes, 300mA is fine. Ignore the datasheet.
