Recessed adjustable up lights combine a cool top lens, long lamp life and energy
efficiency for up lighting trees from lawns or paving. Persius provides a powerful
36 degree up lighting beam, using a single-ended metal halide lamp, while maintaining
a typical top lens temperature of under 70 degrees C - so Persius can be used even
in walkover areas to up light trees with an open canopy and branch structure from
directly below. The lamp and reflector assembly is mounted on an adjustable cradle
so the beam can be tilted up to 20 degrees from vertical to achieve the desired effect.
The dark grey non-reflective interior means less light refraction through the lens
to give away its position in the landscape. Persius has an upper compartment with
a separate top lens insulated by an inner second lens from heat generated in the
lower compartment which houses the lamp and control gear. Persius has a brass lens rim, a cast aluminium body and a polymer sleeve for recessing into the
ground. A sandblasted brass top ring is available for discrete installation in paving,
especially in heritage projects where stainless steel may look too modern.: green
and black tops are also available. An 8mm thick black honeycomb glare louvre (E9500L)
is also available as an accessory: this fits inside the top compartment over the
lower lens to limit visibility of the light source in traffic or pedestrian areas.
To facilitate removal of screws for future re lamping or other maintenance, apply
copper grease to the threads of all screws being fitted for retention of bezels,
grills or other top plates or retaining rings. Copper grease resists degradation
due to heat and protects against difficulty in removing screws, particularly where
stainless steel screws are fitted with aluminium parts. It may also be used on screw
threads of screw-off bezels or glare shields. Ensure surplus is cleaned off with
a solvent to prevent staining in use.
This direct burial in the ground fitting is pre-wired with rubber cable and 20mm
IP68 gland for connection to mains supply via a separate underground joint kit (order
T9969 separately). You will need to provide 300mm depth of shingle drainage below
the uplight: do not use in waterlogged ground.
All recessed luminaries must have adequate drainage beneath each fitting to allow
water to disperse, especially in clay based soil beds. All cable joint must be 100%
watertight and there a number or waterproof transformer boxes and heat shrink cable
joint kits on our web site to choose from. We would advise that all connections and
transformer be kept above ground where possible as the weakest link in any exterior
garden electrical installation is joining cables together.
If you feel that adequate drainage may be an issue then we would advise using a
surface mounted spike light and keep all joints above ground. The Apollo range of
light fittings has a choice of beam angles and glare shield options and can be found
at the bottom of the surface ground lights section.
Please ensure that your electrician is NIC EIC certified and has done exterior lighting
