Garden Lighting Help sheet No. 11: - Recessing brass uplights in paving

If you need to install recessed uplights in paving, you will want to ensure a flush, level fit and prewire the light positions without risk of damage to the lights during installation or cement spill etc spoiling the finish or making final installation difficult. The answer is to install a niche and recess tube during construction and pre-wire them to accept the uplights when construction is finished. The Amphibian and Nautilus ranges of recessed lights are IP68 rated for underwater use in fountains and ponds as well as paving and areas subject to occasional flooding or waterlogging. They are available in natural brass finish, which weathers to blend with stone, or optional chrome or powder coat colour finishes, such as granite for use in granite set driveways. It is also relativelty easy to cut paving to fit around the square recess niches for a neat finish.

Range	Model Numbers	A - Overall depth	B - diameter	C - cylinder depth	D - Flange size
Amphibian	M200, M2002, M2003, M2004	210mm	140mm	200mm	145 x 145mm
Nautilus II	M2506, M2507, M2508, M2509	102mm	100mm	100mm	110 x 110mm

Lay a 100mm diameter duct along the line of lights required so that the top of the duct is the correct depth below the finished paving level for the model of uplight to be fitted – see table above.
Drill a hole of at least 25mm diameter in the top of the duct pipe at the position of the light.
Draw a low voltage ground burial cable from the transformer position through the hole in the duct, leaving a 0.5 metre length free above the duct. Installation is easier using one cable per light.
Install the tube and niche over the hole in the duct at the position where the light is to be installed; the top of the flange of the recess niche should be level with the paving. Loop the low voltage cable inside the tube and tape over the hole in the niche to prevent debris falling into the tube.
After paving is completed, connect the cable of the recessed light to the cable from the transformer by means of a crimped joint in heat shrink tubing using Cable Joint Kit (CJK) T9962. If “looping through” use T9963 cable splice kit
Drop the recessed light into the niche and tube for a perfect flush fit in the paving, fastening the grub screws in the lens recess of the light to secure the body in place in the niche.

NB: The lens of a recessed light fitted with a halogen lamp of more than 20watts may become very hot in use. Use models with grill where hot lenses must be shielded or where the lens should be protected from stones in tyre treads etc.
