JVC RS400 / 500 / 600 lamp aging thread

[AVSCraig]

How is your lamp holding up ? My RS600 so far ( all measurements in low lamp ) -

Brand new - 12 / 8 / 2015 - 285 Lux = 1161.98 lumens.

1 - 6 - 2016 ( 45 hours on lamp ) - 272 Lux = 1108.98 lumens.

11 - 21 - 2016 ( 258 hours on lamp ) - 224 Lux = 913.27 lumens.

Looks like I'm down about 21% from new. With my Stewart Cima Neve I can still get 22.89 foot lamberts in low lamp ( iris open ) and easily get 16 or 17 foot lamberts with the manual iris closed down a bit.

LEDs and Laser eliminate the loss over time don't they?

I dont have a way to measure the Lumens.  I have about 300 hours on my bulb...I use low light mode with auto iris 2

You need to get a light meter. How do you know how many foot lamberts you are watching at ?

Nice to see someone documenting the lamp cycle, im exited to  see how many hours you will get out of the lamp.
Been thinking abour buying a RS500/ 600  for comparison purpose, but will wait to they get cheaper.

i dont know to be honest....my previous PJ when caliobrated locally was at 16Fl...and this is noticeably brighter...so more than that? lol...I should get it calibrated professionally....and/or a meter

That would certainly slow the dimming. Too bad there aren't more choices of home theater projectors with laser or LED under $ 20K. There are a few. In fact we have a couple for sale at AV Science. But I'd like to see more.

You could get a DR. light meter on Amazon for $ 40.00.

This is the ( etter ) one I've had for 6 or 7 years. Very handy.

I'm sure it works, but I wanted something more accurate myself. Bring it and we can compare readings.

Chad B is a great choice.  I'm hoping to get him out in December for my RS500.

Pulled it out and I will put it in the car so I don't forget.
