RGB Three-Color Laser Large Venue Projector 20000 Lumens WUXGA 1920x1200 DLP Large Venue Laser Projector

Output at this level is not hard to produce. The usual route is a blue laser firing into a spinning phosphor wheel, which converts it into white, and a colour wheel that splits that white back into primaries before the light reaches the panel. The T1LU2 takes the other route: red, green and blue come from independent MCL laser diode modules and are combined directly, with no phosphor wheel and no colour wheel in the light path. The difference is not a marketing label — it decides what happens to your colour at the moment the image gets demanding.

A conversion step is a loss step. Phosphor absorbs blue laser energy and re-emits a broad white spectrum; a spinning segment filter then throws away two thirds of that white to produce a single primary. The energy that is thrown away does not vanish — it becomes heat inside the chassis, which is why bright wheel-based projectors grow large, loud and power-hungry. Removing both the wheel and the conversion removes that tax. The T1LU2 puts its 850 W into light rather than into a disc that has to be cooled and timed.

This is where the architecture shows up in the specification: colour brightness is ≥100% of white brightness. On a wheel-based projector the colour figure sits well below the white figure, and the gap widens as output climbs — which is why a bright projector so often looks washed out on saturated content. Here the two figures are equal at 17,000 lm. A deep blue night scene, a saturated brand colour, a full-gamut mapping frame: each carries the same output as a white test pattern. The brightness you bought is available on the content you actually show.

The colour volume runs to ≥110% of BT.2020 and ≥150% of DCI-P3. That puts two reference spaces inside the projector's range rather than at its edge: Rec.709, where corporate and broadcast material is authored, and DCI-P3, where cinema content is graded. Combined with colour brightness at parity, this is the combination that matters: a wide gamut that dims when you use it is a spec sheet entry, not a picture.

The complete projector is rated at 17,000 lm and measures 20,000 lm at screen centre. Use them for different jobs. Quote 17,000 lm when you compare models, because that is the whole-unit figure. Use 20,000 lm when you plan a blended wall: edge overlap dimming removes brightness from the seams, so the centre figure tells you what margin you are working with.

Neither number is labelled ANSI on the datasheet, and we do not present them as ANSI. If a tender needs an ANSI value with a report, ask us for the factory test report.

Three things, and they are the reason to step up from the 10,500 lm model in the same series:

• Screen area: at the same brightness density you cover roughly 60% more surface, which is the difference between a 16:10 image that reads at the back of a hall and one that does not.
• Ambient tolerance: with house lights up and windows unshaded, the image still holds contrast instead of greying out.
• Blend headroom: on a multi-projector canvas, the extra output is what you spend on overlap, geometry correction and a uniform final canvas rather than on a bright centre and dim edges.

Frame uniformity is specified at 90%. In a blended wall this matters more than the centre number: two projectors can match at centre and still show a seam if their corner falloff differs, and no blending software hides it cleanly. Contrast is specified at 6,000,000:1 as a dynamic figure; the datasheet carries no static/FOFO value, so treat it as the manufacturer's headline number rather than a like-for-like comparison against a static specification.

The chassis takes seven lenses spanning 0.50:1 to 7.20:1 — 0.50–0.60, 0.64–0.95, 1.04–1.65, 1.59–2.39, 2.40–4.00, 2.70–4.50 and 4.50–7.20 — with the 1.59–2.39:1 fitted as standard. Coverage runs from a short-throw position in a small gallery to a long-throw position at the back of a hall, from one body; the gaps sit around 0.60–0.64 and 0.95–1.04, so send us the throw you have rather than picking from the list.

Four lenses are motorized with memory and calibration, so a saved position returns exactly after a swap. Lens shift reaches H ±36% and V ±117.5% — the vertical range exceeds the screen height, so the projector can hang above or sit below the frame and still be aimed optically instead of by keystone.

Rotation covers 90°, 180° and 270°, with front, rear, ceiling-front, ceiling-rear and automatic ceiling detection mounting modes, so portrait and inverted positions are supported orientations. Keystone reaches ±30° in both axes and the geometry set adds four-corner and curved-surface correction plus edge blending.

Connectivity covers 2 * HDMI, USB Type-C, 3D Sync in and out, DMX512 in and out, RS232 in and out, dual RJ45, dual wired remote and dual USB-A at 5 V / 1 A, with HDBaseT optional and expansion for SDI in/out, SFP optical input and HDMI output. Crestron, AMX Discovery and PJLink run over the network ports, so the projector becomes one addressable node in a room system.

Because there is no wheel to wear and no lamp to change, maintenance reduces to filters and the occasional lens swap — the difference between servicing on a schedule and servicing after a failure. Plan cooling for a sustained 850 W: this is not a unit to box into a closed cabinet.

• Large halls and auditoriums where the screen is wide enough that 10,500 lm would read thin at the back row.
• Museums and visitor centres with long daily cycles and colour-critical content.
• Venues with ambient light you cannot fully control — glass atriums, daylit foyers, exhibition floors kept lit for visitors.
• Multi-projector canvases where the extra output is spent on overlap instead of a bright centre.
• Any room where one projector has to cover both a wide 16:10 format and a 2.35:1 cinema format without a lens change mid-programme.
