Bollard and pole light heights

Three families that look like one category and are specified in three completely different ways. One has standard heights, one is built to your drawing every time, and one publishes a figure that is not a mounting height at all.

01

A bollard is specified by where the light sits, not by the post

The height of a bollard decides two things at once: how far the light throws, and whether it glares. Raise the optic and the pool widens but the source climbs towards eye level. Lower it and the light is comfortable but you need more of them.

Enlighten Pro’s cast bollards cluster deliberately at one height. Of the 43 codes that publish a figure, 18 are 600mm, and most of the rest are pairs or ranges built around it — 250/600, 300/600, 600/750, 300/500/800. The bodies are aluminium casting, most commonly 150 × 150mm square.

HeightWhat it doesWatch for
250–300mmMarks an edge — a step, a planter, a level changeLights the ground, not the path; spacing gets tight
500–600mmThe working height for a footpath or driveway edgeNothing much — this is why it is the common size
750–800mmWider throw, fewer fittings, more presence in the landscapeThe optic is closer to eye level; shielding matters

Above 800mm you are no longer choosing a bollard. A post-top light on a short pole does that job better, because the optic can be aimed and shielded rather than simply raised.

The heights above are standard, not a limit. They are the sizes held as stock geometry. Any of them can be made to a client drawing or specification — that is how most site-specific work runs here.

02

Why a pole light has no catalogue height

Of 54 pole-light codes, only 15 publish a height — and that is the correct state of the record, not a gap in it. A pole is made to the requirement: the height, the wattage and whether it carries one arm or two are decided per project.

Read the published figures carefully. On a pole light the numbers describe the luminaire — the 15 that carry a height record something between 250mm and 550mm, with bodies around 325 × 325mm to 425 × 425mm. Nothing about a pole is 375mm tall. The pole is separate, and it is yours to set.

What you decideWhy it is not in a catalogue
Mounting heightSet by the road or path width and the spacing you can achieve, not by the fitting
Single or twin armA twin arm halves the number of foundations on a divided carriageway; on a footpath it doubles the cost for nothing
WattageFollows from height and spacing — the same fitting is specified at 50W and at 100W on different projects
Pole materialMild steel on 34 of the 54 codes, aluminium on 18. Coastal sites change that answer

The practical consequence: send a layout, not a model number. A drawing with path widths and the positions you can actually get a foundation into tells us more than any code does, and it is the only way to answer the wattage question honestly.

03

A gate light’s height is the fitting, not the mounting

This is the one that is most often misread. A gate light sits on a pillar, and the pillar decides the mounting height. The figure in the catalogue is the size of the lantern.

Across 40 gate-light codes, 35 publish both. Bodies are aluminium casting, most commonly 225 × 225mm square, and heights run 200–250mm. So the sizes here are genuinely fixed in a way the pole range is not — a gate light is a finished object, and it is chosen to sit in proportion on the pillar it lands on.

Proportion is the whole decision. A 150 × 150mm lantern on a 450mm pillar looks lost; a 250 × 250mm lantern on a 300mm pillar overhangs it. Measure the pillar cap before choosing the code.

Sizes can still be customised to a drawing where the pillar demands it — the difference from a pole light is that here the standard sizes are the usual answer, not the exception.

One deliberate difference in the specification: gate lights are supplied at Ra 80+, not the Ra 70 that is standard elsewhere outdoors. They light an entrance a person stands at, and colour matters more there than the last few lumens per watt.

04

Spacing follows from height, and nothing else

There is no universal spacing figure, and any guide that gives you one has skipped the step that matters. Spacing is a consequence of mounting height, the beam the fitting throws, and the uniformity you are willing to accept.

The useful way to hold it: a light source illuminates an ellipse whose size scales with its height above the surface. Double the height and the same fitting covers roughly four times the area at a quarter of the level. That is why raising a fitting always lets you space further apart, and why it always costs you illuminance directly under it.

MountingTypical useWhat sets the spacing
300mmStep and edge markingContinuity of the line — gaps read as missing fittings
600mmFootpath, driveway edgePath width; a wider path needs both sides or a taller fitting
800mmLandscape, wide walkwaysOverlap between adjacent pools at the darkest point
PoleRoads, campuses, parkingHeight, throw and the uniformity ratio the project is held to

Where a project is held to a numerical uniformity or average illuminance, the honest answer is a calculation against the actual photometry, not a rule of thumb. Send the layout and the target and we will run it.

05

What IP65 and Ra 70 are doing on an outdoor spec

Two figures on every outdoor sheet are widely misread, and both are deliberate choices rather than defaults.

IP65 is the outdoor standard here

The second digit is what matters outdoors: 5 means protection against water jets from any direction, which is what rain plus a hose amounts to. It is not an immersion rating — a fitting that will stand in water needs IP67 or IP68, and those are a different family. The IP ratings guide covers what the digits do and do not promise.

Ra 70 is a decision, not a compromise

Outdoors, lumens per watt is usually the figure the project is judged on, and colour rendering trades directly against it. So Ra 70+ is standard across the outdoor range, with Ra 80+ available on request. Gate lights are the exception and ship at Ra 80+, because they light a threshold rather than a carriageway.

Colour temperature

3000K, 4000K, 5000K and 6000K are the standard offering and are held in stock. Anything between 2700K and 6500K can be supplied to order. Warmer reads better in landscape and residential entrances; cooler is usual on roads and industrial approaches.

06

What to send us

Because so much of this range is made to the requirement, a short list of facts gets a real answer faster than a model number does.

  1. The layout. Path or road widths, and where a foundation can actually go.
  2. The mounting height you want — or the constraint that sets it, if there is one.
  3. Single or twin arm, for anything on a pole.
  4. The target, if the project is held to one — an average illuminance, a uniformity ratio, a tender clause.
  5. The environment. Coastal, industrial or heavily planted sites change the material answer before they change the optical one.
  6. The pillar cap size, for gate lights. It decides the code.

A blank height in the catalogue is information. On this range it means the dimension is set per order, not that it is unknown. Where a size is published it is the standard offering, and it can still be customised to your drawing or specification.

Heights, arm configuration and wattage are made to your requirement — the layout tells us more than a model number does.
