BenQ LH830ST 4000lms 1080P Laser Simulation Projector
Commercial-Grade 1080P UST.
Built To Run.
You're installing once and you want it to last. Maybe it's a multi-bay commercial sim facility. A training center with all-day projector use. A dedicated home sim built with care into a basement or garage where dust is part of the environment. The BenQ LH830ST is the commercial-grade 1080P ultra short throw laser projector — 0.496 fixed throw fills screens up to 300 inches, IP6X dustproof sealing (the highest rating available), Blending Ready preset for multi-projector deployments, LAN-based OTA firmware updates, Golf Mode color calibration, and a sealed laser engine rated for 20,000 hours.
Built by BenQ — the world's #1 projector brand for four years running, trusted in homes, boardrooms, classrooms, simulation bays, and commercial installations worldwide. Dedicated golf-simulator projector line since 2021.
Three Things The LH830ST 1080P UST Projector Does For Commercial Installs.
What makes BenQ's IP6X-sealed 1080P UST laser projector the right pick for permanent, long-term, or multi-projector installations.
0.496 Ultra-Short Throw
Fills screens up to 300 inches from feet away. A 120" screen needs 4.3 feet; a 150" screen needs 5.4 feet. Ideal for tight bays, classrooms, basements, and converted commercial spaces.
IP6X Sealed + Blending Ready
IP6X dustproof rating — highest available. 20,000-hour laser life. Blending Ready preset and factory WBA calibration for multi-projector commercial deployments. LAN management + OTA firmware.
Golf Mode + 93% Rec.709
Purpose-tuned Golf Mode picture preset for course color accuracy. 93% Rec.709 coverage with 30-bit depth. Cinema, Entertainment, HDR10, and HLG modes for movies, sports, and streaming.
You Probably Recognize Yourself In One Of These.
Three buyers we see for the LH830ST — ultra-short throw, commercial-grade sealing, and multi-projector capabilities serve different needs.
You're Building For Long-Term Commercial Use
Multi-bay facility, training center, retail showcase
- Exhibition halls, training facilities, retail showcases, themed entertainment

BenQ LH830ST Key Specifications & Performance Data
15W built-in speaker · 360° installation · 30dB Normal / 24dB Eco · 230W typical · 7.48 lbs compact body
What You're Actually Getting.
0.496 Ultra-Short Throw — Up To 300 Inches
The LH830ST's 0.496 throw ratio is among the most aggressive in BenQ's golf simulator lineup — projecting images up to 300 inches from distances that would be impossible for standard or short-throw projectors. A 100-inch screen fills from just 3.6 feet; a 120-inch from 4.3 feet. The 116% offset lifts the image naturally above the lens without requiring excessive tilt. Screen Fill switches instantly between 16:9, 16:10, 4:3, 1:1, and 5:4 aspect ratios from the remote.
IP6X Sealed — Highest Dust Rating Available
The LH830ST carries an IP6X dustproof rating — complete protection against dust ingress, the highest dust-resistance rating available. For commercial sim facilities with heavy foot traffic, training centers with continuous use, or home installations in dusty environments (garages, basements, carpeted rooms), IP6X sealing is the difference between a projector that runs reliably for years and one that needs constant maintenance. The laser starts instantly with no warm-up time, delivers 20,000 hours in Normal mode and 30,000 in Eco, and is rated for 24/7 continuous operation.
Blending Ready + WBA + LAN Management
Blending Ready Mode provides a one-click OSD preset that applies key settings to prepare images for multi-projector edge blending — dramatically reducing setup time across multi-unit deployments. BenQ White Balance Adjustment (WBA) factory-calibrates white balance consistency across units before they ship — eliminating color mismatch between adjacent projectors. LAN-based OTA firmware updates push current firmware to all connected projectors simultaneously, eliminating the operational overhead of manual, unit-by-unit maintenance.
Golf Mode + 93% Rec.709 + HDR10
Golf Mode calibrates color specifically for simulation software — optimizing fairway greens, sky blues, and course textures so the simulator looks natural and immersive. 93% Rec.709 color coverage with 30-bit depth (1.07 billion colors) ensures accurate, consistent color across all picture modes. Switch to Cinema, Entertainment, HDR10, HLG, or sRGB for movies, sports, and streaming. The 15W built-in speaker handles casual listening — connect external audio via the 3.5mm output for a complete home theater setup.
What Ships With The LH830ST
Projector body, remote, and power. Fixed lens is built-in. The LH830ST is the commercial-grade 1080P UST in BenQ's value tier — same physical chassis as the LK830ST 4K UST, with IP6X sealing and Blending Ready features at the 1080P price point.
- BenQ LH830ST 1080P UST laser projector
- Remote control with battery (RCA011)
- Power cord (1.8m)

Picking between LH830ST, LK830ST, and AH500ST?
The LH830ST is the right choice if you want commercial-grade 1080P UST features (IP6X, Blending Ready, LAN) at value pricing. The LK830ST ($2,499) is the same physical platform with native 4K resolution and 4.2ms gaming input lag — worth $500 more if you want 4K. The AH500ST ($1,999) trades commercial features (IP6X, Blending Ready) and 10 percentage points of color gamut for 8,000 additional Eco laser hours — better if longevity is your top priority.
