What's the average laser life of a CDJ-player?

I was wondering how long the laser inside a CDJ player (e.g; Numark CDX or PioCdj1000mk3 etc) would last ?
I have been told that the average life span of such a laser is 1000-1500 hours? Is this information correct? I can't find any source about it.
Personally I think it's possible, as all lasers fade out one day. When you're a good gamer you should know that the Laser quality of a Playsation 2 isnt that high, and most players will have to buy a second one after quite some time. My Gamecube seems to encounter this problem too: the laser is getting weaker and weaker.
Can this comparison be made an does anyone know the approximate lifetime of a decent cdj-laser ?
Thanks :) |

The lifespan is much greater than 1000-1500 hours. Such a low lifespan is true for some types of lasers, but the lasers used in CD/DVD decks are diode units which are highly reliable.

| If the laser gave out after 1000 or 1500 hours, your talking a big investment (CDJ 1000 MK2/MK3s) going out the window...basically a big waste of money, since those cost around $1,000 - $1,300 a piece. Pioneer would have some pretty pissed off customers...they would need some type of replacement plan if that happened, and by then i'm sure your warranty would be over... |

Usually with higer end audio/video equipment it is not the best answer to just go out and buy a new one. There are probably many shops that will service CDJs and that may include replacing the laser. A good person to ask would be a club owner because I am sure their turntables and CDJs run alot and see all sorts abuse. |

Like the article I sent out said... the diode type lasers have a lifespan similar to that of an LED, which is around 100,000 hours.
Waaaay more than you'll be using it. Have you have seen many DVD/CD players with bad lasers? Or CD-ROM drives? Not really...

| Laser diodes last about ~5000 hours when not overpowered. Overpowered will decrease the life of the diodes (some of which MAY use crystals to get a wavelength needed to read the cd). You arent really going to use it 5000 hours in 2 months. More like 5-10 years. I know my 95mW nexus from wickedlasers.com isn't going to run out in my lifetime. It's guarenteed. |

| You are more likely to experience some form of mechanical failure or perhaps circuity issues before the laser goes out. |

Ok... Thanks for the info :)
Just one more issue: What is the exact difference between a Playstation laser (they are diodes too, arent they ?) and the one of a CDJ Player.
Just google and you'll find many issues regarding the laser of a console. They die out after 4-5 year... Well they don't die out completely but they're not capable of reading discs anymore. Cleaning the lens only postpones the problem in time.
Can this problem also occur on a CDJ player? I have never heard of it before, but can't find any info about it either :)
I was only told it can happen (of course the shopkeeper could be a moron too :tongue2) |

Cleaning the lens wont do anything except clean the little piece of plastic or glass that collimates the beam making the disc readable. The diode gives off light and when it does...it looks like \/ and spreads like that, with a collimation lens it'll come out like that, but hit the lens and go into | and slightly diverge over distance. The diode will burn out after about 5000 hours. Which im guessing is around $50 to fix since 808nm and 1064nm diodes are cheap, and the crystals will never need replacing to get to the wavelength needed ro read. |
