There are various projectors used in Full Flight Simulator as LCoS equipment to produce visual image. One of the vital elements of projector is Projector Lamp. Market can offer JVC, SONY or even BARCO LCoS projectors.
Lamp quality and used work time is pretty obvious to every spectator. LCoS projectors lamps have a trend to go dimmer over time thus producing darker image. The regular lamp lifetime is estimated up to 2000 hours. Every time Projector hours meter should be re-set to zero value to get ability estimate the lifetime of new installed lamps.
However even if you are taking care of your projector, lamps still may work longer or shorter period of time in comparison with officially estimated numbers.
In our simulator Boeing 737 there are installed LCoS projectors JVC DLA-RS2. Our actual experience tells that “BHL 5009-S” Lamp useful lifetime is pretty varying when longest actual lifetime reached up to 3500 hours and shortest is slightly under 500 hours since brand new lamps were installed.
Keep in mind the fact that shortest lifetime was considered when lamp condition became unstable and caused to shut down projector to StandBy mode every 30 minutes. After failing lamp replacement the same projector was working fine again.
I would say there is no big surprise, but JVC OEM lamps provided the longest lifetime in comparison with other aftermarket products.
