Our take
UHL55 is a source-documented 4K UHD output projector with LED illumination, autofocus, Wi-Fi, and a built-in media player. Optoma lists 2500 LED lumens, but that is not labeled ANSI; the saved datasheet does not establish the underlying imaging device's native horizontal pixel count or a specific streaming-app platform. Its 1.2:1 conventional throw needs room depth. The candidate title includes the RFBA suffix and says Renewed; neither the suffix-to-variant mapping nor any specific unit's condition is confirmed here.
Home viewing where 4K UHD output and a conventional projector distance fit better than native-device certainty or UST placement.
It is not a documented native-4K-imager pick, a verified ANSI-brightness choice, a guaranteed built-in streaming-app device, or an ultra-short-throw option.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Optoma specifies 4K UHD output and LED illumination for the UHL55 model.
- Autofocus, Wi-Fi, and an onboard media player reduce some external setup needs.
- A 1.2:1 throw ratio and fixed optical zoom provide documented placement context.
What to weigh up
- Native imaging-device pixel width is not established by the saved datasheet.
- The 2500 LED-lumen claim is not an ANSI rating and is not converted here.
- The RFBA renewed listing's exact revision, condition, and app services remain unknown.

What the features mean for you
Separate UHD output from native imaging resolution
Optoma describes the UHL55 as a 4K UHD projector and lists an output of 3840 × 2160. The saved model datasheet does not clarify the native horizontal pixels of the underlying imaging device, so that profile field remains unknown. This distinction matters when a shortlist separates native 4K from pixel-shifted or processed UHD output. The UHL55 can still be compared as a model with documented UHD output, but the source does not support claiming a native 3840-pixel imager. Check the exact model information if native pixel structure is a firm purchase requirement.
Treat 2500 LED lumens as its original stated basis
Optoma lists brightness as 2500 LED lumens, not ANSI lumens. Those measurement labels are not interchangeable, and the value is not entered into the ANSI match field. This protects comparisons with models such as BenQ TH585P, for which the manufacturer does explicitly state ANSI lumens. Room light, screen gain, image size, and a used projector's operating history all matter in practice. Ask for a picture at the intended size and room light rather than infer performance from an unstandardized number. This review does not report personal brightness tests or certify a renewed unit.
Autofocus and media playback offer setup convenience
The datasheet identifies autofocus, Wi-Fi, and an onboard media player. Those functions may reduce the need to connect a computer for locally stored material and can simplify a room where a regular HDMI source is not always present. The manufacturer material saved here does not identify a certified app platform or name supported streaming services. A media player and wireless network are not proof of Netflix or another protected service working. If streaming applications are central, verify the installed software and service support on the exact device or plan to connect an external HDMI player.
Measure the conventional lens position
UHL55 uses a 1.2:1 conventional throw ratio and a fixed optical zoom range, with autofocus helping once the projector is in place. It is not designed to sit immediately beside the wall. Measure the screen width and the lens-to-screen distance before choosing furniture or a ceiling mount; autofocus cannot change projection geometry. The saved document does not establish optical lens shift, so digital corrections should not be mistaken for that installation adjustment. Also leave clearance for ventilation and confirm that the placement preserves access to the ports and power connection.
Keep renewed condition and model suffix separate
The frozen row says UHL55RFBA and Renewed, while Optoma's source identifies the UHL55 model family. The suffix has not been mapped to an exact revision, and the listing condition does not reveal operating hours, prior service, or package completeness. This review is for UHL55-series specifications only; the Amazon link is an exact-model search rather than a direct ASIN. Ask for the unit label and check focus, image uniformity, autofocus, remote, wireless connection, media playback, ports, fan, and included adapter. No current stock, price, or individual-unit test is represented.
What else to compare
For a documented native Full HD image and 3500 ANSI lumens, compare BenQ TH585P. For an integrated and explicitly documented app platform, compare Anker Nebula Cosmos Max while noting its native imager pixels also remain unresolved.
Before you buy
Is the UHL55's imager natively 3840 pixels wide?
The saved Optoma datasheet confirms 4K UHD output but does not establish native imaging-device pixel width.
Can 2500 LED lumens be treated as 2500 ANSI lumens?
No. Optoma labels this figure LED lumens, not ANSI, so the values are not converted or compared as equivalent.
Does the UHL55 guarantee streaming apps?
The datasheet lists Wi-Fi and a media player but does not establish a supported streaming-app platform or current services.

The decision
UHL55 suits buyers who want documented UHD output and LED media features, provided they accept non-ANSI brightness and unresolved native-device and variant details.
