Hello, I have a Beam 2R from elation that has been having lamp issues. The lamp fades out after 10 minutes of fixture usage then fades back in after being off for about 3-5 minutes(haven't exactly timed it). This keeps happening when the fixture is operating. The lamp has 412 hours of usage and is rated for 3000 hours. Any assistance in resolving this issue would be much appreciated. Thank you!
