JVC RS400 / 500 / 600 lamp aging thread
« on: November 30, 2016, 10:19:59 AM »
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?

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.

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.

This is the light meter I use...$16.99

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.
