Doesn't the vertical design send more heat radiation to the LCD right on top of the light?

I don't want to make this design due to that problem, but was just curious about it. I like the folded design laying horizontally so that I can push it flat onto the wall.

HUH?

The light is the same distance from the lcd whether you use a straight shooter or a folded design vertical or horizontal. I don't understand your question.

Since the LCD is on top. Hence heat rises, wouldn't the surface of the LCD get hotter than if you put the LCD on the side or on the bottom.

Although, it's in a small space, I'm not sure it matters anymore. I could be wrong.

I don't think it matters since you are pulling cool air across the lcd. There have been plenty of vertical PJs built that don't have heat issues.

Haven't built a vertical, but you probably just want optimize your fan placement to ensure you avoid a hot pocket of air sitting against your heat shield. BoomerBrian is right of course - you shouldn't be too concerned about hot air rising toward your LCD panel if you are drawing cool air down past your panel at the same time
