Dimming the Brightness of LED Strips
Our#85503LEDStripDimmeradjusts thebrightnessof your single-colorLEDStrip.Itwill plugdirectly intobarrel plugof the#85501PowerSupplyandbarrel jackofsingle colorLED strip.Use#85553BarrelPlugAdaptorand22AWG wire to connectto#85502PowerSupply.
No more cutting and soldering!

Power Supplies
A full reel (5 meter) LED strip at fullbrightnessrequires6Ampsat12VDC.Our#85501PowerSupplyprovides thispowerandcanoperateone full LEDstrip.Topowermore than5metersof LEDstriplights, use two (ormore)of our#85501power supplies.Wealsoofferour#85502power supply thatprovidesup to33Ampsat12VDCandcanoperateup to five fullreels (25meters)of LEDstrips. It usesaterminal strip with 3 pairs of 12VconnectionsfordirectwiringofLEDstrips.
Color Controller for Multi-Color LED Strips
EachLEDchipon theMulti-Color stripactually contains three individual LEDS;one red,onegreen,andoneblue.Anycolor canbeproducedby varying theintensityof the individual colorchannels.Ourcolorcontroller canselect specificcolorsorcreatevariouscoloreffectsandsequencesbycombiningcolors.Colorcontrollercomeswithawireless(infrared)remotecontrol.Thecontrolboxhasabarrel jack connector for thepower supply.The infraredsensor isona shortlengthofwirewhichletsyouplacethecontrolboxoutofsightwhilekeepingthesensorvisibletotheremotecontrol.The4-pinconnectorplugsintotheMulti-ColorLEDstrip:Justlineupthearrowsonthetwoconnectors.Usetheremotecontroltosetcolorsorrunsequences.

WhenpoweringLEDLightStrips,youmayfind that the lightsarebrighteratoneendof thestrip thanat theother,especiallywhenyouhavemultiplelightstripsconnectedinadaisy-chain(endtoend)fashion.Tobalancethelightoutput,you'llneedtoprovideadditionalpowerfeedstotheconnectionpointsbetweenstrips.Youmayalsofeedthepowerintothecenterofthestring,orfeedfrombothends,oratvariouspointsalongthestringofstrips.Besuretoconnectall(+)connectionstogetherandconnectall(–)connectionstogether;otherwise,youwillshortoutthepowersupply.
