i1lt has been sitting in a draw for years. Still ok to use?

I have an Eye One LT that has been sitting in a dark draw since that last time I used it back in 2009. I assume at this point it won't be accurate since I know calibration drifts with time. Should I just throw it away or does it have any useful purpose at this point? Can it still measure lumens accurately or serve any other useful purpose?

I am planning on buying a new meter soon but I wanted to ask about the i1lt before I just junk it.

I have one that is about a year newer, I am hoping to do a comparison with an i1d3 a bit later, I will post results once done. I did this about a year or so ago (did not document) the i1lt was way off from the i1d3.

Hi, Eye One LT (aka i1Display 1) had 3 exposed filters, low grade quality (to keep the price low); natural aging (even when stored well)/humidity had already discolored them, this has degrade the meter accuracy a lot, making it un-usable I believe.

Since you don't have a spectro to use as a reference to do a comparison, it's unknown how much has been drifted.

Now with i1Display PRO (i1Display 3); it has dichroic filters which are sealed with rubber o-rings. Due to it's design, the meter's life is extended and this prevents drifting also.

It sounds like buying a new meter is what I should do. Thanks for the responses!
