    Regarding knock-off bulbs: Why are you mentioning Kr-95 (gross error; should be Kr-85) as a problem? The possible amount of this low energy radioactive isotope is inconsequential even if it were to exist in the bulbs. You are playing on fears of people with limited knowledge of actual radiological risk compared to the natural environment of radiation surrounding us at all times. Correct your thesis; remove this fear mongering.

      Hi Gary,
      Thanks for pointing out that typo. We have corrected it to read KR-85. We found this paper from the Environmenal Protection Agenecy about the health risks associated with Krypton 85: a Review of the Literature and an Analysis of Radiation. While we are not trying to fear mongering, we think people should be informed and make their own decisions about generic, compatible projector lamps. Thanks for the input.
