Case file
Direct-view LED, OLED, microLED and laser projection — selected to the room's lux, throw, sightline and content.
/ The discipline, in detail
How we approach led panels & projectors.
We work backwards from the content. A ballroom showing key-note slides at 1,200 lux ambient light is a different problem from a dark cinema running 4K HDR film. Each demands different brightness, gamma, contrast and gamut. We measure, model and specify accordingly — never one-size-fits-all.
On record
Every led panels & projectors engagement is documented end-to-end — design, programming, commissioning, calibration — and handed over with the files our successors would need if we were never to return.
/ Where we deploy this
Active across 4 sectors.
LED Panels & Projectors is rarely a standalone brief — it sits inside a wider sector practice with its own codes, expectations and operating rhythm.

/ Frequently asked
LED Panels & Projectors — what buyers ask first.
Laser projector or LED wall for our auditorium?
Choose a 4K laser projector for auditoriums under 250 seats with controlled lighting; choose fine-pitch LED above 250 seats or where the wall stays lit. A 4K laser projector with a BenQ screen is typically the right answer at half the cost of LED. Above 250 seats or where the wall stays lit, fine-pitch LED earns its premium.
When is a projector still the right choice over LED?
When the screen size needs to exceed about 150 inches diagonal, or when the budget for that size of LED is unjustifiable. A 4K laser projector with a BenQ screen at 200 inches still delivers a very competitive image at a fraction of the LED cost. The trade-off is ambient light tolerance — LED handles ambient light better.
Laser, lamp or hybrid projector?
Laser is the right answer for any new projector deployment in 2026. 20,000-hour light-source life versus 3,000–5,000 hours for lamp; better colour stability over time; instant on-off; quieter operation. The projector premium is now under 30% and falling; lamp projectors should be reserved for budget-constrained refresh of existing installations.
What's the right brightness for a given room?
Rule of thumb: ANSI lumens needed = screen area (sq ft) × ambient light condition (50 for dark cinema, 200 for boardroom with curtains, 500 for atrium with daylight). We model each room with the actual fenestration before specifying. Under-specifying brightness is the single most common projector-install mistake.
How do you handle motorised screen and projector lift integration?
Both are part of the same control system as the rest of the room. A single 'Film' scene drops the projector lift from the ceiling, lowers the screen, dims the lights, closes the drapery and powers the audio chain — over about 20 seconds, choreographed. Manual override is always available.
Can projection screens reject ambient light?
Ambient light rejecting (ALR) screens (BenQ StarGlas, Screen Innovations Black Diamond) reduce off-axis ambient pickup by 70–85%, which makes daylight viewing genuinely watchable. The trade-off is a narrower viewing cone and higher cost. We specify ALR for media rooms with daylight; matte-white for dedicated cinemas.
