david.elsbury Posted March 16, 2011 Share Posted March 16, 2011 Do you mean having a flat field, rather than a peaked field in the profile, Jeremy? Link to comment Share on other sites More sharing options...
Jeremy MLS Posted March 17, 2011 Share Posted March 17, 2011 Yes. So although the brightness does diminish noticably with the lamp in the flat position (although it was fine as a projection on to the cyc, in our application) it will run at 100% fine and reduces the chances of accidentally burning it out prematurely.

Nicktaylor Posted November 2, 2011 Share Posted November 2, 2011 When I bought my one Pacific, I got the high powered one by accident. Therefore unless you run it at tick over the laminate does suffer over time. I assume the lamps are radically different or can a lower powered bubble be slotted in? Just recently the idea of laminate projection has come up and I want to experiment again Nick Link to comment Share on other sites More sharing options...
Don Allen Posted November 2, 2011 Share Posted November 2, 2011 I was taught to lower the 600w lamp into the Pacific base to reduce the power and the heat that gets to the fergo. This is the opposite to peaking a lamp when you fit a new one tp a fixture. I would try a 600w lamp in a 1200w base as it may have the same misadjustment as lowering a 600w base. Why is acetate being used as a term ?as they are plastic projection sheets. Link to comment Share on other sites More sharing options...
Nicktaylor Posted November 2, 2011 Share Posted November 2, 2011 Thanks for the tip. As to acetate who cares! Its the name of the topic I piggy backed on! Link to comment Share on other sites More sharing options...
ramdram Posted November 3, 2011 Share Posted November 3, 2011 Coemar do a LED profile (v,v expensive) which can display "everything" from an ordinary metal gobo to a picture printed on acetate from your "household" printer. Owing to the LED "light engine" being much, much cooler than a tungsten lamp the acetate does not suffer heat damage. Link to comment Share on other sites More sharing options...
Dmills Posted November 3, 2011 Share Posted November 3, 2011 On the Pacific, one trick is to actually read the manual! Specifically, the 1KW (red handled lamp base) will ALSO take a 650W T class lamp (MUCH Less light, but you can get the lamp center where it needs to be)!! It is in the manual, but is NOT documented on the spec sheet. Going slightly past flat on the lamp helps as well. I have had good luck with this even with standard Pacific gobo holders, and even with the KW lamp it works if you use high temperature acetates and don't get silly. Regards, Dan.

timsabre Posted November 3, 2011 Share Posted November 3, 2011 Why is acetate being used as a term ?as they are plastic projection sheets.It's because the sheets of plastic used on overhead projectors are generally known (in the UK at least) as "acetates". Presumably they used to be made out of acetate, which is a type of plastic. I think they are polyester these days. Link to comment Share on other sites More sharing options...
