I purchased a new ZB SC150 discharge lamp for my ADJ Concept 2. When I fired it up the other night, I noticed that is output was substantially dimmer that the other Concept 2 I have. The output was somewhat orange-yellow...not the bright white that I expected. I checked the obvious such as the color wheel , etc. Everything else seemed to be ok. Any ideas what might be causing this?
I would hate to have to buy another lamp if I don't have to.

Thanks for your assistance.

Hello Jan. You will need to see if all of ther optics are clean and free from dust and residue. I would also like to know the exsact brand of the lamp and the model name on it.
