The KES-410ACA laser is the latest found in PS3 40GB consoles, these lasers are a totally new design where they have separated the blueray and DVD sections of the laser in to two eyes, we guess this is to extend longevity of the laser. Note that these lasers are not compatible with consoles that had the old 400A lasers in them, so you need to make sure the laser that is in your console already is a 410ACA and not an older one. If you have been unlucky enough to have one of these KES 410ACA lasers die on you, these brand new replacements will get you going again. We have a 6 month replacement warranty on these lasers for hardware failure.
