How to cut, connect & power LED Strip Lighting

Hello and welcome to this LED supplies instructional
video on how to cut, connect and power LED Strip. We’ll start by looking at how to cut
LED strip down to achieve the length you need To cut the strip you simply need a pair of
sharp scissors Before cutting the LED strip it’s important
to understand a number of key aspects relating to this product. The strip can only be cut
at the points that are marked. These cut points are clearly shown by a line across the strip
as you can see here The cutting distance for LED strip varies.
In the samples we have here you can see the cut distance is 100mm for LED strips with
30 LED’s per metre, 50mm for strip with 60 LED’s per metre, 25mm for strips with 120
LED’s per metre and 15mm for strips with 240 LED’s per metre”
Once you have found the cut line marked on the LED strip simply use the scissors to cut
directly along the line as demonstrated here Its important to note that LED Strip must
ONLY be cut at the specified marks. Cutting the strip in the wrong place will result in
some of the LED’s in the cut area not working In this example, you can see that the strip
has been cut incorrectly. There are two LED’s not lit. Whilst here you can the one that
has been cut correctly is fully functional. The LED strip in this example is warm white
LED strip from our selection of single colour LED strip lighting, although the same rules
apply when cutting our range of colour changing RGB strips
Now let’s now move on to how a connection can be made to the LED Strip.
We supply our LED strip in lengths of 1 Metre or on full 5 Metre reels. For every length
of LED strip you order, it will be pre-fitted with a 2.1mm input socket as shown here. This
input cable is part number C4229 should you wish to order additional units. If need to
cut down the strip, you will need to take steps yourself to be able to power it as of
course cutting the strip down will remove the pre-fitted C4229 input socket
There are two ways to make additional connections to the strip when you no longer have the pre-fitted
input socket to make use of. You can either use a clip on connector or make soldered joints.
We will look at the clip on connectors first These connectors come in a range of sizes
to match standard tape widths of 8mm and 10mm as shown here, and no tools are required to
fit them Each full 5 metre reel of our LED strip is
supplied with 5 of the appropriate clip on connectors. These types of connectors are
not suitable for use our Ultra High Brightness series of strip due to its high power output.”
“To use these connectors offer the connector up to the LED strip and ensure that the RED
wire is aligned with the + mark on the strip and that the BLACK wire is aligned with the
— mark on the strip” To fit the connector, gently pull back the
black locking bar, Insert the tape into the slot until it is fully located and ensure
that the copper connection points are within the body of the connector”.
“To complete the connection push back the little black clip into its locked position
by applying equal force to both sides until it meets the body of the connector, this will
lock the tape into position” “Gently pulling on the strip will show that
it is locked into place and that a good connection has been made” .As you can see the LED strip
now has 2 wires connected to it. You can use an LED driver which has screw terminals as
input and output connectors to add power to the strip as we show here. Alternatively,
these clip on connectors can be used in conjunction with our part number C4349 to facilitate quick
powering using a standard power supply which we will demonstrate now
You can see that order code C4349 is marked with + and — on its casing to indicate which
way round the wires should be connected. The LED strip is also marked with a + and — so
make sure that the wire connected to + on the LED strip is connected to + on the C4349
and do the same for the — wire. Locate the wires in the screw terminals as demonstrated
and tighten up the screw terminals. Then to power the LED strip simply plug the connector
from the power supply into the C4349 We will now briefly look at soldering onto
LED strip. Soldering is our recommended method as it provides a more secure connection. Here
we are soldering our order code C4229, the little 2.1mm input socket cable, onto a length
of single colour LED strip. As before you can now quickly power it up using a standard
power supply. All of our non-waterproof LED strip featured
in this video comes with a sticky tape backing as shown here. This backing can be peeled
off and the LED strip can then be stuck down to an appropriate flat clean surface. Wood,
metal & plastic surfaces are generally fine. For a quality finish you may like to consider
our range of Aluminium extrusion for LED strip, a selection of this is shown here. The Aluminium
extrusion helps to protect the strip, helps to diffuse the light and also assists with
the cool running and long life of the product. Please see the Aluminium extrusion section
on our web site for more details We’ll now look at powering LED strip. It’s
important that you don’t run too much LED strip as a single linear length or the high
current being drawn into the strip can cause damage. We suggest that for 4.8W per metre
strip, a maximum run of 10 metres is powered, and for 9.6W per metre strip a maximum of
10 metres if powered. If you do need to power more than this, then the LED strip should
be wired in parallel to the PSU to avoid any damage.
When selecting a power supply, we suggest allowing 20% headroom. By this, we mean if
your LED strip requires 48W, 20% added to 48W is 57.6W so the next largest power supply
would be our 60W power supply. Its OK to use a power supply that can provide more than
is required. By you should never use a power supply that is rated the same as your strip
requires or less. To calculate how much power in Watts you need.
Simply multiply the Watts per metre of the strip by the length of strip you are powering.
So if you are powering 5 metres of 4.8 Watts per metre strip just multiply 5 metres by
4.8W per metre giving you 24 Watts. Then adding the 20% headroom onto 24 watts gives you 28.8
Watts, so a power supply rated at 30 Watts or 40 Watts would be perfect. Even a 60 Watt
or 90W power supply is acceptable as your LED strip will only draw the power it needs
from the PSU Here we have a selection of our most popular
power supplies The SW4010E is
a 12vdc 1 amp PSU so can provide 12 Watts
SW3114-A is 12vdc 2 amps so can provide 24 Watts
SW4500 is 12vdc 3.5 amps, so 42W Sw3783A is 12vdc 5 amp so can offer 60 watts
SW4333 is 12vdc 7.5 amps so 90 Watts max That concludes this video on cutting, connecting
and powering LED strip. We hope you have found it useful. Please refer to our web site for
