So as for the testing. Ran the unit for 1 minute and checked the line voltage, 120V even, wires were on the 125V tap. moved to the 120V tap. Noticed the LTU were moving much faster. Did a full 81 LTU test. Prior results on the 125V tap was 9:20. New results moved to the 120V tap at 81 LTU is 6:54.
Well I exposed two screens today at 81 ltu after the voltage change. Exposure time was 6:40. But both screens were underexposed. So while the ltu seems to be going faster, I think the screen still needs to be exposed for 90 minutes. Going to order a new lamp from m&r
The new lamp as of March 5th was exposing 90 LTU right at 5 minutes. I haven't really been timing it but a few days ago i noticed it seemed to be taking longer than normal. Today I timed it and it is now back over 9 minutes. Lamp is one month old with around 200 cycles on it and no better than where i started. They shouldn't be losing this much efficiency this fast should they? I am thinking there is something else wrong with the exposure unit causing the lamps to wear faster than normal.
