Main trade-off
Epson EpiqVision Ultra LS650
Screen support stops at 120 inches and two HDMI sockets can fill quickly.
Head-to-head
Epson LS650 vs LS800: 650 has eARC, 800 extends the screen to 150 inches
The short answer
Choose the LS650 for a screen up to 120 inches and an eARC soundbar setup. Choose the LS800 for a supported 150-inch picture or another HDMI input. Both use simultaneous-color 3LCD. The larger-screen model does not improve every audio connection.
Before you choose
The reasoning and the trade-offs
A 150-inch upgrade needs more darkness than the lumen gap suggests
LS800’s output rating is about 11 percent higher. A 150-inch picture has 56 percent more area than 120 inches. Those figures do not preserve light per square foot when enlarging the screen. Daytime viewers should consider keeping the smaller picture.
What this is based on
Epson EpiqVision Ultra LS650: 3,600 white and color lumens. Screen-area ratio = 1.5625. Epson EpiqVision Ultra LS800: 4,000 white and color lumens. 4000 / 3600 = 1.111.
Main trade-off
Epson EpiqVision Ultra LS800
A larger picture consumes its modest output increase. Audio return is ARC rather than eARC.

What matters in practice
The differences that matter
A 150-inch upgrade needs more darkness than the lumen gap suggests
LS800’s output rating is about 11 percent higher. A 150-inch picture has 56 percent more area than 120 inches. Those figures do not preserve light per square foot when enlarging the screen. Daytime viewers should consider keeping the smaller picture.
How we reached this conclusion
Epson EpiqVision Ultra LS650: 3,600 white and color lumens. Screen-area ratio = 1.5625. Epson EpiqVision Ultra LS800: 4,000 white and color lumens. 4000 / 3600 = 1.111.
The smaller model can be the better soundbar partner
LS650 has eARC while LS800 lists ARC. If high-bandwidth audio must travel from the projector to the soundbar, the higher model number does not settle the choice. Check source format and soundbar support together. A receiver changes the routing options.
How we reached this conclusion
Epson EpiqVision Ultra LS650: Two HDMI inputs, one with eARC. Epson EpiqVision Ultra LS800: Three HDMI inputs, one with ARC.
A short lens does not guarantee a shallow TV stand
LS650’s body alone is 15.7 inches deep before the required installation gap. For either model, use the cabinet and screen-height drawing. Multiplying throw ratio by picture width does not tell you how far the chassis sits from the wall.
How we reached this conclusion
Epson EpiqVision Ultra LS650: 15.7-inch chassis depth and 0.26 optical lens ratio. Epson EpiqVision Ultra LS800: 0.16 optical lens ratio. Chassis-to-wall gap is a different measurement.

Will either projector fit your room?
The result checks hard limits only. Preferences stay out of the calculation.
Epson EpiqVision Ultra LS650
Does not fit these inputsFor a 120-inch 16:9 picture, the calculated lens position is about 2.27 ft. Your input is 9.50 ft.
Epson EpiqVision Ultra LS800
Does not fit these inputsFor a 120-inch 16:9 picture, the calculated lens position is about 1.39 ft. Your input is 9.50 ft.
Distance is measured from the lens to the screen. The calculation uses a 16:9 image and the verified optical throw range for each exact model.
For an ultra-short-throw model, the gap behind the cabinet is a different measurement. Check the installation diagram for cabinet position, screen height and ventilation.

Meaningful differences
What changes the fit
| What changes | Epson EpiqVision Ultra LS650 | Epson EpiqVision Ultra LS800 | Why it matters |
|---|---|---|---|
| Supported picture | 60 to 120 inches | 80 to 150 inches | 150 inches rules out LS650. 70 inches falls outside LS800’s stated range. |
| Audio return | eARC | ARC | High-bandwidth audio routing can favor the smaller model. |
| HDMI count | Two | Three | Audio return occupies a socket on either model. |
| Published white and color output | 3,600 lumens | 4,000 lumens | The larger-screen option gains about 11 percent in headline output. |
| Cabinet planning | 0.26 optical throw, 15.7-inch-deep body | 0.16 optical throw | Lens-to-screen calculations do not give the back-of-projector wall gap. |
What you give up
Every choice has a cost
If you choose Epson EpiqVision Ultra LS650
- A narrow body does not mean a shallow cabinet. The chassis is 15.7 inches deep before adding the installation gap.
If you choose Epson EpiqVision Ultra LS800
- The 0.16 wide and 0.40 digital-zoom figures do not describe an optical zoom lens.
Recommendation switch
The decision flips if...
Your screen will stay at 120 inches or smaller
Choose Epson EpiqVision Ultra LS650. A compatible soundbar benefits from eARC
You want a supported 150-inch picture
Choose Epson EpiqVision Ultra LS800. An extra HDMI input would simplify your external sources
