We compared Craig's meter with mine, and mine showed about 25% higher readings. It appears mine would be a good deal if you are just concerned with monitoring light loss over time where a better meter would be better to verify you have the light output you want.

2.5%...that's not so bad.  Oh, wait, that must have been a floater. 
25%...Ouch!  That's out of range even for govt work.  So, no saving that $23.  But worth more than that to know the difference...Thanks for the comparison!

Just to be clear this was compared to Craig's Meter not the $40 one. Craigs Meter was the 2nd one linked at $179.

So, I haven't yet taken my Black Friday $80 Spyder 5 Express out of the box, and now you're saying I need to spend a c-note more first to tell me how gloriously bright is the light from my RS400? 

Are you sure Craig's meter isn't reading 25% low

Two other questions come to mind: 1) Is the $17 meter linear in its error, and 2) How can we get a comparison including the $40 meter?

We don't know which one is correct... I am assuming Craig's is as it is way more expensive. Neither one of us has a professional verified calibrated one.

If you have a JVC RS400/500/600 you dont have any financial issues whatsoever.. More like having a problem  finding a spot in the garden where you have not already been hiding money.

And a projector like that deserve to be tweaked to perform its best at all times, so i cant imagine anyone having a problem spending the money needet to get the right gear for the job.. Most might have a problem to find out how to actually use the tool, and if thats the case its best just to pay someone to do it every 200-300 hours.

Right.  I've got to learn to use the emoji, as in "Are you sure Craig's meter wasn't 25% low? ;)"

No... we just compared the 2 to see if they came up with the same readings, which they didn't.

Problem is, how do you know that your meter is the one that is wrong? Maybe Craig's reads 25% low. Or the real number may be somewhere in between the two.

Yes it does pose a problem without having a calibrated meter to compare to... I am assuming that a more expensive meter would have a better chance of giving a more accurate reading, but I don't know. All we have proven is that 2 different meters can give 2 different results.

Except my AEMC CA813 has produced readings that were consistent with others - 970 lumens for the RS4910 in high lamp, 1150 lumens for my RS600 in low lamp etc. Ron's cheap meter read about 28% higher than mine. Adding 28% to those numbers I just posted would be outside the norm of what other people with better meters than mine have gotten measuring those projectors. About 28% higher.  Just FYI.

Hey Mike - do you have lamp measurements with your RS600 ?

Ok, let's re-kindle this thread ...
Has anyone been keeping a log of the light decay, then plot it?
Curious to see it if so.
