Outdoor Stair Lighting

Lighting outdoor steps is a safety question before it is a design one — especially in winter, when the treads are wet or iced. One principle governs everything: light should fall across the tread, not into the eyes of the person coming down.

Three ways to mount it

ApproachAdvantageWatch out for Recessed into the side wallLight runs along the tread, no glareNeeds a back box built in at construction Recessed into the step itselfPicks out the nosing, looks strikingMust take footfall and frost — look for IP67 Wall light above the flightSimplest to installCasts shadow across the nosings

Spacing and output

Wall-recessed fittings go in every second or third step, 15–20 cm above the tread. You need very little light — 50–100 lm per fitting is plenty. Overdoing the brightness causes glare and actually makes the step edges harder to read.

Water and frost

IP65 is the minimum. Where fittings sit in the step and water can pool, aim for IP67. Check the driver's operating temperature range too — fittings intended for indoor use often will not start in hard frost. Anodised aluminium copes best with a northern European winter.

Common questions

How often should step lights be spaced?

Every second or third step, 15–20 cm above the tread.

What IP rating for outdoor step lights?

IP65 for wall-recessed, IP67 where water can collect in the step.

What colour temperature outdoors?

3000 K. Warm light suits a facade and avoids the cold, clinical look at an entrance.
