how long do bluray lasers last?

[raggie33]

just wondering how long the laser in a ps3 should last

If the diode is conservatively driven, I'd fully expect a 5,000+ hour lifetime (to 50% intensity).
But I have no evidence or documentation with which to back this up, so please take this value with plenty of crystalline sodium chloride (grains of salt).
