Our take
Consider the LP70+ when a lightweight projector must serve an older presentation source and native XGA is sufficient. Its input panel, conventional throw, and used-lamp uncertainty make it a specific legacy fit rather than a general home-theater recommendation.
A legacy presentation setup where low carrying weight and the documented DVI or analog source path matter more than HD detail.
It is a poor match when native Full HD or 4K detail, built-in streaming, battery operation, or a direct modern HDMI connection is essential.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The 2.4-pound body is unusually light for a lamp-based projector of its era.
- InFocus documents a 1.85–2.35:1 manual zoom range and focus adjustment.
- DVI/M1-DA, composite RCA, and S-Video support several legacy source types.
What to weigh up
- Native 1024 × 768 XGA has less detail than WXGA and Full HD panels.
- A 120 W UHP lamp is specified, but no used unit's hours or remaining life are known.
- The checked input list does not include HDMI, so modern sources may need a verified adapter path.

Full review: how the features affect your choice
What the features mean for you
Is native XGA enough for the material?
InFocus identifies the LP70+ as a mobile DLP projector with a 0.7-inch XGA DMD and native 1024 × 768 output. That resolution can display slides and older computer sources, but it leaves less room for fine interface text, dense spreadsheets, or small captions than a native WXGA or Full HD panel. A compatible source signal does not change the projector's native pixel grid. If the screen will be large or viewers sit close, compare the required text size and viewing distance before choosing it. Its 1,500 ANSI-lumen manufacturer figure does not resolve that detail tradeoff: resolution and room brightness answer different questions, and neither says how a particular used lamp performs today.
Treat the lamp rating as an original specification
The InFocus-authored sheet lists a maximum of 1,500 ANSI lumens and a 120-watt UHP lamp rated for 4,000 hours. ProjectorCentral's archived specifications list 1,400 ANSI lumens and 3,000 hours, so the checked sources disagree. This review uses the manufacturer sheet as its stated specification basis rather than selecting the larger number as a performance advantage. Neither source establishes the output or remaining lamp life of a used unit. The lamp may have been replaced, dimmed, or operated for an unknown number of hours, so ask for the individual projector's service history and confirm replacement-part support before depending on it for recurring presentations.
Mobile does not mean close-wall placement
The LP70+ is light enough to carry, but its 1.85–2.35:1 throw ratio is a conventional projector distance. Measure lens-to-screen distance for the intended image size rather than assuming that the word mobile means it can sit near a wall. InFocus documents manual zoom and focus, plus vertical digital keystone adjustment up to 15 degrees. Keystone can correct a modestly tilted image, but it does not replace optical lens shift or a short-throw lens. A fixed desk, ceiling mount, or marked presentation position can make the setup predictable; a cramped room should be compared against a genuinely short-throw model instead.
Check every source connection before buying
The datasheet lists DVI/M1-DA, composite RCA, S-Video, and audio inputs. That panel is useful when a laptop, document system, or video source already has compatible outputs, but it is not a direct HDMI connection. A modern computer may need an adapter that carries the correct video signal, and an adapter's compatibility should be confirmed before purchase rather than assumed from connector shape alone. The checked materials do not establish a streaming platform or local media playback. This projector therefore makes most sense when a known external source is already part of the room and the cable route can be tested with the exact equipment.
Who should choose the LP70+?
Its 2.4-pound weight favors a presenter who moves equipment between rooms, while the lamp and older input panel favor someone who can inspect and maintain a known unit. The checked sheet does not establish battery operation, so do not treat the lightweight body as permission to run without an outlet. Choose it when the existing source needs DVI or analog video and XGA detail is acceptable; choose a newer native-HD projector if fine text, current connections, or long-term lamp support is central. Compare the exact unit's lamp hours, image uniformity, focus travel, remote, and adapter needs. The right decision depends on that physical setup, not on a rating printed for a new projector years ago.
Compare for your needs
If the room can use a larger fixed projector and needs a documented brighter presentation rating, compare the published InFocus LP850. Its installation-class body and XGA image solve a different problem, so inspect the weight, lens, inputs, and lamp condition before choosing either model.

Before you buy
Does the LP70+ have native Full HD resolution?
No. InFocus specifies native XGA at 1024 × 768 pixels, below a native 1920 × 1080 Full HD panel.
Can I connect an HDMI-only laptop directly?
The checked datasheet lists DVI/M1-DA and analog inputs, not HDMI; confirm a compatible signal adapter for the exact laptop.
Does the 4,000-hour lamp rating describe a used unit?
No. It is the original lamp-life rating; verify the actual projector's lamp history and operating hours.

The decision
The LP70+ is a narrow but understandable choice for mobile legacy presentations: its low weight and DVI/analog connections are useful only when the source path is known. Native XGA detail and an unknown used lamp should stay central to the buying decision.
