You can use a par38 lamp & fixture vertically without any problem, they often point upwards at things, and as they have a rubber collar seal to stop the water running in around the lamp there should be no issues.

You could wire a photocell to the circuit at another point as opposed to right next to the light, they don't have to be close together.

Or you could save a few quid a year in electric and blown lamps by using a small led fitting. A plastic GU10 external 'spike' fitting with a 4 or 5 watt led will give a far more directional light for a fraction of the power consumption and the bits will be less than 20 quid.

Basically, it means that you should choose a fitting (light) which is designed such that it does not allow the ingress of moisture, splashes, etc.

In your particular instance, it means that whatever light fitting you choose should be water & weather tight.

I can get my hands on a couple of these if they are any use to you?
I also have a second hand Union Jack somewhere if you are interested

They are flood lights so the spread of light might be too
wide for you
