SUNLITE 3.9 OUT XL

The SUNLITE 3.9 OUT XL is an outdoor LED panel with a 3.9 mm pixel pitch, supplied in a one-metre by one-metre cabinet. It is the format that installs fastest: one square metre per panel, one fixing, one cable run — a 24 m² facade goes up in twenty-four moves instead of forty-eight.

Behind the stated 3.9, the actual pitch is 3.90625 mm — 250 divided by 64, the standard grid of outdoor modules. That value matters: it yields exactly 65,536 pixels per square metre, or 256 × 256 dots on a one-metre cabinet. Resolution figures land on whole numbers, with no rounding to correct afterwards.

What a 3.9 mm pitch means for the viewer

The LED grid stops being perceptible from roughly 6.7 metres, and fine image detail is fully resolved from 13.4 metres. Below 6 metres the eye starts to pick out individual dots. This is the right pitch for a shop facade seen from a wide pavement, a roundabout, a forecourt or a retail park entrance — not for a screen people walk past at arm's length.

8,000 nits: the real reason

The 8,000 candelas per square metre are not there to dazzle. They are there to stay legible when sunlight strikes the screen surface. An outdoor display does not fight darkness but reflected ambient light: facing south at midday, a 3,000 nit panel looks grey. At 8,000 nits, contrast holds. Automatic brightness control then drops the screen to a few hundred nits at night — without it, the screen becomes a nuisance to neighbours and a source of complaints.

Construction

SMD1921 LEDs — the reference package for outdoor use at a 3.9 mm pitch, encapsulated to withstand UV and freeze-thaw cycles. IP65 rating: dust-tight and protected against water jets from any direction. 1/16 scan, 6,500 K colour temperature.

Position in the range

The SUNLITE 3.9 also comes in an L format, a one-metre by fifty-centimetre cabinet, for when the available height does not fall on a whole number of metres. For viewing distances beyond twelve metres, the SUNLITE 6.9 OUT XL covers the same area with a third of the pixels: at that distance the eye no longer tells the difference, and the budget changes order of magnitude.

Avec un pitch de 3.9 mm, SUNLITE 3.9 OUT XL couvre les distances de vision moyennes (3 à 8 m). Conçu pour un usage outdoor, ce module combine 8000 nits et un rafraîchissement professionnel, soit l'ensemble des paramètres attendus sur une installation B2B professionnelle.
