hello and welcome to this led supplies instructionalvideo on how to cut, connect and power led strip. we'll start by looking at how to cutled strip down to achieve the length you need to cut the strip you simply need a pair ofsharp scissors before cutting the led strip it's importantto understand a number of key aspects relating to this product. the strip can only be cutat the points that are marked. these cut points are clearly shown by a line across the stripas 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 with30 led's per metre, 50mm for strip with 60 led's per metre, 25mm for strips with 120led'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 cutdirectly along the line as demonstrated here its important to note that led strip mustonly be cut at the specified marks. cutting the strip in the wrong place will result insome of the led's in the cut area not working in this example, you can see that the striphas been cut incorrectly. there are two led's not lit. whilst here you can the one thathas been cut correctly is fully functional. the led strip in this example is warm whiteled strip from our selection of single colour led strip lighting, although the same rulesapply when cutting our range of colour changing rgb stripsnow 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 lengthof led strip you order, it will be pre-fitted with a 2.1mm input socket as shown here. thisinput cable is part number c4229 should you wish to order additional units. if need tocut down the strip, you will need to take steps yourself to be able to power it as ofcourse cutting the strip down will remove the pre-fitted c4229 input socketthere are two ways to make additional connections to the strip when you no longer have the pre-fittedinput 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 sizesto match standard tape widths of 8mm and 10mm
as shown here, and no tools are required tofit them each full 5 metre reel of our led strip issupplied with 5 of the appropriate clip on connectors. these types of connectors arenot 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 redwire 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 theblack locking bar, insert the tape into the slot until it is fully located and ensurethat the copper connection points are within the body of the connector"."to complete the connection push back the
little black clip into its locked positionby applying equal force to both sides until it meets the body of the connector, this willlock the tape into position" "gently pulling on the strip will show thatit is locked into place and that a good connection has been made" .as you can see the led stripnow has 2 wires connected to it. you can use an led driver which has screw terminals asinput 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 quickpowering using a standard power supply which we will demonstrate nowyou can see that order code c4349 is marked with + and -- on its casing to indicate whichway round the wires should be connected. the
led strip is also marked with a + and -- somake sure that the wire connected to + on the led strip is connected to + on the c4349and do the same for the -- wire. locate the wires in the screw terminals as demonstratedand tighten up the screw terminals. then to power the led strip simply plug the connectorfrom the power supply into the c4349 we will now briefly look at soldering ontoled strip. soldering is our recommended method as it provides a more secure connection. herewe are soldering our order code c4229, the little 2.1mm input socket cable, onto a lengthof single colour led strip. as before you can now quickly power it up using a standardpower supply. all of our non-waterproof led strip featuredin this video comes with a sticky tape backing
as shown here. this backing can be peeledoff 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 considerour range of aluminium extrusion for led strip, a selection of this is shown here. the aluminiumextrusion helps to protect the strip, helps to diffuse the light and also assists withthe cool running and long life of the product. please see the aluminium extrusion sectionon our web site for more details we'll now look at powering led strip. it'simportant that you don't run too much led strip as a single linear length or the highcurrent being drawn into the strip can cause damage. we suggest that for 4.8w per metrestrip, a maximum run of 10 metres is powered,
and for 9.6w per metre strip a maximum of10 metres if powered. if you do need to power more than this, then the led strip shouldbe wired in parallel to the psu to avoid any damage.when selecting a power supply, we suggest allowing 20% headroom. by this, we mean ifyour led strip requires 48w, 20% added to 48w is 57.6w so the next largest power supplywould be our 60w power supply. its ok to use a power supply that can provide more thanis required. by you should never use a power supply that is rated the same as your striprequires 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 by4.8w per metre giving you 24 watts. then adding the 20% headroom onto 24 watts gives you 28.8watts, so a power supply rated at 30 watts or 40 watts would be perfect. even a 60 wattor 90w power supply is acceptable as your led strip will only draw the power it needsfrom the psu here we have a selection of our most popularpower supplies the sw4010e is a 12vdc 1 amp psu so can provide 12 wattssw3114-a is 12vdc 2 amps so can provide 24 wattssw4500 is 12vdc 3.5 amps, so 42w sw3783a is 12vdc 5 amp so can offer 60 wattssw4333 is 12vdc 7.5 amps so 90 watts max that concludes this video on cutting, connectingand powering led strip. we hope you have found
it useful. please refer to our web site forother videos in the series
