TL;DR — Framed posters look their best under even, warm, glare-free light aimed to wash the wall rather than bounce off the glass. The practical tools are picture lights, adjustable track or wall-washers, and warm LED bulbs around 2700–3000K; the practical enemies are direct sunlight and any lamp reflected in the glazing. This guide covers how to light art in a bar, restaurant or home.

The goal: even light, no reflection
Good art lighting does two things: it lights the paper evenly, and it keeps the light source out of the viewer’s line of reflection. A lamp aimed straight at glazing bounces back as a bright hotspot that hides the image; the same lamp angled to graze the wall lights the poster cleanly. Aim to wash the surface, not to spotlight the glass.
Fittings: picture lights, track and wall-washers
A picture light mounted on the frame or wall above throws a soft, even wash down the sheet — the classic, reliable choice. Adjustable track or recessed wall-washers let you set the angle: the rule of thumb is roughly a 30-degree angle from the wall, steep enough to avoid reflecting into the room but shallow enough not to cast the frame’s shadow across the art.
Avoid a single narrow spotlight aimed head-on; it creates glare and uneven pooling. Several softer sources almost always beat one hard one.
Colour temperature and the aged palette
Vintage lithographs have a warm, aged palette, and warm light flatters it. Choose LED bulbs around 2700–3000K (‘warm white’); cooler, bluer light makes the creams look grey and the reds dull. A high colour-rendering index (CRI 90+) keeps the colours true. In a bar already lit warm for atmosphere, the art usually just needs a gentle top-up, not a different colour of light.
Protect as you light
Light is also what fades art, so protect while you illuminate. Keep framed posters out of direct sunlight entirely, use UV-filtering glass where daylight is unavoidable, and prefer LED, which emits little UV and almost no heat, over halogen. Even, warm, UV-controlled light is the combination that makes a print look its best and keeps it that way.

Frequently asked questions
How should I angle a picture light?
So it washes the wall rather than reflecting off the glass — roughly a 30-degree angle from the wall avoids both glare and the frame casting a shadow across the art.
What colour of light is best?
Warm white LED, around 2700–3000K, with a high colour-rendering index (CRI 90+), which flatters the warm aged palette of vintage posters.
Can lighting damage a poster?
Light causes fading. Keep prints out of direct sun, use UV-filtering glass near daylight, and prefer low-UV, low-heat LED over halogen.
