Bollard light pictures

I do not have much to say about the bollard lighting in the pictures below. They are just pictures of existing lights that I saw on my way back from my workout routine at a local gym. However, for readers who have to deal with the installation of this type of landscape lighting, I did attach in this post a section diagram that shows a little bit more details. I hope it helps.

Well, I thought this bollard light looked nice at the children playground near at rest area and food stalls on my way from the gym.
Picture 2 – A closer view



This is just a closer view. It looked nice.

Landscape lighting falls within the jurisdiction of landscape architects. So I do not normally spend much time with them.

When I have to prepare an external lighting layout that also include the landscape lighting during a concept design stage, I usually just copied the general layout of a landscape lighting from previous projects, prepare the electrical distribution system for the lights and count the number of light fixtures.

The purpose was to capture a rough approximate of the cost for the landscape lighting works. We must get the money first. Once the money is available, there are so many ways to get the job done.

Picture 3 – Another view that I liked



Diagram 4 – Section diagram of a typical bollard light installation



This section diagram show a little bit more details of a typical bollard light fixture.

I use this to show the typical installation details so the contractor can price in their cost.

The actual look and design of the light are always decided by the architect or the landscape designer of the construction project.

The rating of the lamp inside does not have to be 70 watt. Depending on the architectural design, the wattage of the bulb can be as low as you can find in the market.

However, the underground cabling, the internal wiring and the bulb holder and accessories should be selected for the highest rating because the owner may decide to opt for much brighter lighting of the compound in future.

The smallest bulb wattage is usually installed where the bollard lights are meant as walk lights along garden paths.
In any case, all these architectural decisions should be done by qualified people. I never pretend to be good in these things.

Unless I am doing it for my own house, of course.

The size of the concrete stump in Diagram 4 is generally dictated by the diameter of the base plate of the bollard light. Allow for at least one inch between the mounting bolt and the edge of the stump.

The depth or the height of the stump would depend on the type of the soil and the environment where you install the light.

If there is a possibility that persons may be leaning to the light pole, then the stump should be made to give more stability.

An electrical contractor asked me this question a few days ago. I just said 500 mm would be nice and he did just that.

The mounting bolt was cast in to the concrete, not drilled in to avoid possible breakage if the quality of the concrete is poor.

Picture 5 – Another type of bollard light



This is another design of bollard light. It was installed not far from the above type. I assume this was done in the first phase of the construction there.

It does not look as cute as the first type above, but in my opinion it does suit the surrounding compound. Don’t you agree?

This last picture is to complete the bollard lighting topic.

The electricity to the light fixtures must come from somewhere and there has to be a distribution board and a control panel to control all the compound light fixtures including the bollard lights.

This weatherproof electrical panel is where the electric supply and the control were located.

Inside it were the circuit breakers, the electric shock protection devises and the timer control circuit that turns ON and OFF the lighting at specified times.

Take notice that the electric shock protection is an extremely important matter in the installation of a compound lighting including these bollard lights.

This is not a minor issue because now and then there are always members of the public who get electrocuted and died as a result of touching one of the landscape and compound lighting poles or fixtures.

However, this is a serious topic by itself and I will not discuss it here.

Hi, can you please let us know what is the most appropriate or best type of Conduit to use for containing wires that connect to an Outdoor Socket? Thank you.
