The catch
Epson EpiqVision Ultra LS650
Supported screen size ends at 120 inches, and two HDMI sockets can fill up fast.
Side by side
Epson LS650 vs LS800 for screen size, cabinet and soundbar: 800 extends the screen to 150 inches, 650 has eARC
Quick verdict
The LS650 covers a screen up to 120 inches and an eARC soundbar setup. The LS800 is for a supported 150-inch picture or an additional HDMI input. Simultaneous-color 3LCD is used in both. Audio connections do not all get better on the larger-screen model.
Before you buy
Why, and what it costs you
Going up to 150 inches calls for more darkness than the lumen gap implies
About 11 percent higher is LS800’s output rating, while a 150-inch picture has 56 percent more area than 120 inches. Those figures do not preserve light per square foot when the screen is enlarged. Anyone watching in the daytime should consider keeping the smaller picture.
Where this comes from
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 catch
Epson EpiqVision Ultra LS800
A larger picture uses up its modest increase in output. Audio return is ARC and not eARC.

Differences you will notice
Going up to 150 inches calls for more darkness than the lumen gap implies
About 11 percent higher is LS800’s output rating, while a 150-inch picture has 56 percent more area than 120 inches. Those figures do not preserve light per square foot when the screen is enlarged. Anyone watching in the daytime should consider keeping the smaller picture.
How we worked this out
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 may pair better with a soundbar
LS650 has eARC, while LS800 lists ARC. When high-bandwidth audio has to travel from the projector to the soundbar, the higher model number does not decide the matter. Check source format and soundbar support together. Adding a receiver changes the routing options.
How we worked this out
Epson EpiqVision Ultra LS650: Two HDMI inputs, one with eARC. Epson EpiqVision Ultra LS800: Three HDMI inputs, one with ARC.
A short lens is no guarantee of a shallow TV stand
The body of LS650 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 from the wall the chassis sits.
How we worked this out
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.
Plug in your numbers
Will either projector work in your room?
This checks hard limits only. Personal preferences are left out of the math.
Epson EpiqVision Ultra LS650
Does not work with your numbersFor a 120-inch 16:9 picture, the calculated lens position is about 2.27 ft. You entered 9.50 ft.
Epson EpiqVision Ultra LS800
Does not work with your numbersFor a 120-inch 16:9 picture, the calculated lens position is about 1.39 ft. You entered 9.50 ft.
Measure distance from the lens to the screen. The math assumes a 16:9 picture and uses the verified throw range for each exact model.
With an ultra-short-throw model, the gap behind the cabinet is a separate measurement. Check the installation diagram for cabinet position, screen height and ventilation.

Spec by spec
Where they really differ
| Spec | Epson EpiqVision Ultra LS650 | Epson EpiqVision Ultra LS800 | In practice |
|---|---|---|---|
| Supported picture | 60 to 120 inches | 80 to 150 inches | 150 inches rules LS650 out, and 70 inches falls outside LS800’s stated range. |
| Audio return | eARC | ARC | The smaller model may be favored by high-bandwidth audio routing. |
| HDMI count | Two | Three | On either model, audio return takes up a socket. |
| Published white and color output | 3,600 lumens | 4,000 lumens | Headline output is about 11 percent higher on the larger-screen option. |
| Cabinet planning | 0.26 optical throw, 15.7-inch-deep body | 0.16 optical throw | Lens-to-screen math gives no back-of-projector wall gap. |
Trade-offs
What each pick costs you
With Epson EpiqVision Ultra LS650
- Don't assume a narrow body fits a shallow cabinet. The chassis alone is 15.7 inches deep, before the installation gap is added.
With Epson EpiqVision Ultra LS800
- Neither the 0.16 wide nor the 0.40 digital-zoom figure describes an optical zoom lens.
Change of plan
When the answer changes
You plan to keep the screen at 120 inches or smaller
Go with Epson EpiqVision Ultra LS650. A compatible soundbar can make use of eARC
A supported 150-inch picture is your goal
Go with Epson EpiqVision Ultra LS800. An extra HDMI input would make external sources easier to connect
