[QUOTE="drew gandy, post: 117759, member: 880"] Re: Video projector suitable for outdoor use I occasionally go to the one remaining drive-in theater in Chicagoland despite my lack of satisfaction with the brightness. Even well after the sun has gone down, dark action movies are rather difficult to view imo. Last year I saw an ad that they had updated their projection (but it wasn't clear when they had actually done it) so I went again. I couldn't tell a difference in brightness. So, the bar set by drive-in theaters isn't very high. Further, there are "standards" for indoor movie theaters that are relatively modest but those levels generally only work in a very well light controlled room. You might be able to achieve that level of ambient light outdoors in a hidden or rural setting when the moon is right but often just the light of street lights will require more lumens from your projection. If the movie can be started after sundown and not during dusk, you can probably get by with much less brightness.
