It's bright, but at the same time not so hot that you need gel extenders or an inventory of HT gels.
We lamp all of our wash lights (PAR/PARNel) at 750w.
All of our ERS at 575w.
And we have 375's on hand for our Jrs in lab situations primarily.
Generally, I use 575s.
If its a long throw, I use 750.
If its a 70˚ or 90˚, I use 750.
And I have a pile of 375s for if I'm touring this one show into ballrooms with limited power or extremely close throws.
So, all of the above I suppose.
The one choice your missing is the 77v lamps for dimmer doubling. But I've never used any of those, so thats OK.
trim in a concert situation.
For me its 575 long life
color temperature, energy efficiency, etc...
I know we have several people who sell lamps for a living and if you could point me in the right direction... Maybe I'm just not trying the right search phrases on Google and CB.
The simple difference is that to have a higher color temp, a lower amount of lumens must be the result of that compromise. That may not answer all of your questions, but should help so you can at least see some of the differences.
wash of 750s is a bit much. Considering we're a high school and only have to throw ~75 feet, 100 at most.
power situation then 575w non extended life. For more important specials and what not, I use 750w non extended life.
I am also in the same boat that I have never seen a 375w before.
color temperature of the 750w.
Of course it depends on the purpose of the light and the unit itself.
trim height is 30' on stage and 60' FOH where I feel like it's necessary.. need some gel extenders badly though for the Par EAs..
instrument plugged it in and turned it on to find out that it didn't work. So I put a 575 in and tried again and it worked fine. Never have touched or used a 750 since.
At school, I we use all 575s except for the fixtures that have I-Cues on them.
At work, it's mostly 575s that go out, with a few orders requesting 750s.
dimmer doubling that makes me giggle
stock for those. when I was in college we used the 575s for our S4s. Might be ordering some 750s for the Shakespeares for the next show.
