Point Source Lighting is the best solution for

through the channel. This solution provides a
continuous ribbon of light within the rail. It is
often more complex to work with, particularly
since it covers shorter distances within each
run and demands increased coordination of
fabrication because the installation requires
more components (i.e. special brackets, post
tops or pipe railing adapters). Its light output
is fixed at various lumens per foot, but most
systems are dimmable.
* An Integrated Linear Module provides a
light engine integrated into the rail itself,
making the LED and lens an integral part of
the rail. It provides better lighting performance than the simple linear stick because
the rail profile has more room for integrated
design, including asymmetric optics and
lensing options. It does not, however, allow

a high degree of customization. The design
is fixed and rails are factory-made to withstand and work with environmental conditions. These are mechanically fastened or
glued systems and cannot be field-welded
due to the presence of electrical circuits.
* A fourth option you should be aware of is inexpensive LED tape that is integrated into a rail.
These systems should be carefully evaluated
since the LED tape can be poorly made, lacking
engineered connections or a means of secure
installation. They tend to have a low cost of entry,
but will demand a higher cost over their life.
In addition to the various types of handrail
lighting installations, lighting is also specified
by color. The color is measured in temperature, with LED's running about 2700K to 3000K,
having the same coloring as incandescent
lights. In general, the industry trends towards
warmer (lower) temperature lights, as they are
more pleasing to the eye.
Technique
Fabricators are uniquely positioned to recommend the specification of illuminated handrails, as they are often in consultation with
owners and detailers during the design process. The most challenging aspect can be coordination with other trades, like masonry and
electrical. When the right system is selected,
it will reduce the burden on all parties and fabrication will be no more difficult than installing
a standard pipe rail. Here's what you need to
know about the different types of installation.
* Electrical Installations - Most LED rail systems require a transformer of 110-277VAC to
24VDC. This transformer needs to be mounted
within an electrical enclosure for safety and
security. Always use the transformer recommended or supplied by the manufacturer.
Always. The use of any other product will void
warranties or cause failures. LEDs require
particular attention to input power and need
to be mated to the proper source. The transformer should be located somewhat close to
the beginning of the circuit, generally within
75-feet. It must be housed in a watertight or
submersible NEMA-rated enclosure, even in
remote mounting locations. Additionally, the
wiring within the railing system is low-voltage
24VDC, considered by the National Electrical
Code to be inherently safe. Systems that provide line-voltage input to the handrail, with
the transformer living inside a post, should be
evaluated carefully if they're being considered
for outdoor use. If water infiltrates a handrail
post, which is not uncommon, isolating the

277VAC circuit within a water-filled handrail
post becomes critical.
* Mechanical Installations - Exercise foresight before you start, as the rail must be
designed to accept the wiring. Feed wire
must penetrate the railing and continue to
the end of the circuit, around bends and
often through returns. Many times, wire pulls
must be provided around tight corners. Lit
handrails also require internal deburring so
wire isn't stripped as it's pulled. It's vital
to secure wire connections, particularly in
public spaces. Make them tamperproof. That
can be as simple as eliminating mechanical
connections or supplementing a mechanical
connection with a smartly-placed weld.
* General Design & Installation - It is a good
idea to complete the circuit layout during the
design phase so drivers can be placed and
conduit run into posts. This is a critical element
of design impacting concrete and electrical
contractors. Illuminated rails install in much
the same manner as a standard handrail with
a few additions. Pull the conduit stub-ups into
the post to allow for connections to be made
and the circuit checked before grouting the
rail in place. Prior to connecting the fixtures,
again check the voltage. Rewiring is far
easier if the fixtures haven't been installed.
Drop the power to the circuit as well. LEDs
do not respond well to hot wiring and can fail
from sudden surges in current, so pay special
attention to the polarity when connecting the
fixtures. LED systems are simple, with just a
positive and negative lead, but an oversight
can burn out components quickly and lead
to delay. After connecting the fixtures, it is
beneficial to tape them in place outside the rail
prior to installing. This allows a quick check
that all wiring is done properly before securing fixtures within the rail. Once the circuit
is checked and functional, drop the power
before installing. Make sure the rails are clean
and oil-free for the cement or silicone adhesive to properly set if using a system requiring
bonding agents.
