Laser Life?


I have an older Pioneer Elite PD-S95 transport. It's working perfectly. Yet, I was wondering if lasers have a limited lifespan. If so, how long? Also, how often should the lens be cleaned? Thanks.

Most small lasers of the type used in A/V equipment are rated in terms of hours of use -- as an example, 5000 hours. That figure, however, is at best a SWAG, since the laser may fail sooner or substantially later. The lifespan of the laser can ber affected by a number of factors, such as how well the internal power supply is regulated (avoiding power spikes is important), the amount of heat the player is subjected to, etc.

I had an Adcom GCD-575 that worked for more than 6 years of fairly frequent use before the laser failed. I suspect that Sean can give us more accurate info, assuming he sees this post.
Yes laser do have a lifespan. I had to change mine in my Esoretic P2. It's been to the dealer since october and the laser is still back order (Grrrrr). but what I can tell you is that I bought the unit 5 years ago and was playing an average of 60 to 80 hours per week. Now all I want is to find maybe a P2s or to the dealer to tell me that i had received the laser and be happy like before...

Marakanetz, The FM is so bad in Houston I sold my tuner years ago and just put a CD on repeat 24/7 to have something playing all the time....I got 61,000 hours out of the first laser which is pretty good service.....
