New semi-long throw set up. Thoughts?

[bigredpastor]

Hi friends:

Here is the proposal:

We need to replace the aging 2700 Lumens projectors (2). Looking upgrade to at least 5000, but probably 6000 lumens

Throw distance 44'6"
Screen size-150" diagonal

The projector first up is the EIKI LC-XL200L- 6000 lumens-paired with the long throw lens -
The EIKI AH-24771 or Navitar 496MCZ500-2.75"-5.0" Focal Length
4.3:1 - 7.69:1 Distance to Width Ratio
2.8 Aperture

In the projectorcentral.com calculator- it shows up on the lower end (low green into the pink section) "recommended for ambient light"

Its within the throw range (43-76.9') but do I want to be on the low end or on the upper end or right in the middle?

thanks for the help!

Taking a quick look at that calculator - I'd start with actual light measurements "fc" which are included above that "slider" applet.

It seems to me that by itself, the term "ambient light" doesn't really tell us much.

FWIW, One church I used to work at had 2 services, a"contemporary" and a "traditional" which used projection only at times and where we kept ambient lighting fairly high. It was an older crowd which liked a bright room (because they were more tied to printed programs - a decidedly "contemporary" technology for those of us who grew up in the 40s/50s )

They built a new Family Life Center" where the contemporary services are now held, but built it with more windows and ambient light than the older service. But since the throw was the same and screens were the same, they figured they use the same brightness.

Didn't work, of course.
