Is it a waste of time calibrating a brand new PJ? What I mean is, should you wait until there are a certain number of hours on the bulb so that any initial brightness / color shifts have past?

Thanks.

If you are doing it yourself, then no (because you can do it several times as lamp ages). If you are hiring services of a professional, then waiting 100 or 150 hrs may be a good idea.

Or simply get the professional to build in two visits as part of the original agreement for services.

Come do it now ... and come back in 4 months and re-tweak it. You get the best of both worlds this way for the same price.

Most professionals should be agreeable to this arrangement ... especially if they are local to you.

Thanks, these are both good points!
