Brushed Aluminium Up and Down Wall Light - IP54

How are the bulbs changed? Do the ends screw off or do you have to remove glass covers and then the bulbs? If so, how do you remove the glass covers?
The top and bottom of the fitting unscrew allowing you to re-lamp the fitting. The glass and cap are as one to ensure the fitting it is IP rated.

Do these have glass covers on both top and bottom?
Yes this is an outdoor IP54 sealed unit.

Is this suitable for use on buildings near the ocean?
The finish of this product is aluminium so no, it is not recommended for use near the coast. A galvanized or copper finish would be more ideal, look at our coastal section for those which are corrision resistant.

What is the diameter of the cylinder please and how tall is the light? Is this weather resilient for outdoors? And finally does it come with an LED light.
The diameter is 75mm and the eight is 200mm. The fitting is IP54, so it suitable for use outdoors (but can be used inside if you wish!). The fitting takes 2 x GU10 lamps, so you could use our GU10 LED lamp inside this. This lamp can be found on the spare lamps section and will pop up when you add this to your basket.
