Yeah a few people have replied negatively about me not using drivers. I figure if an AC adapter is rated at so-and-so Amps and Volts, it better be somewhere near or it would fry the device it's for. Im telling you, an AC to DC adapter is exactly the same thing as a driver. Trial and error had me find out that not all adapters are equal (they are classed by efficiency...), as all drivers aren't either (Ever wonder why the costly U.S. or Swiss brand pull the actual rated wattage? They have great drivers with excellent QC, something most companies DGAF about.). I DO NOT RECOMEND JUST WIRING + and - MATCHING AND HAVING THE DIODES SHINE AND CALLING IT A DAY! I did it at first and it is pretty risque... You gotta understand even if you have a good adapter, there can be voltage spikes and and your gonna be running the adapter beyond what it was designed to do no matter how efficient it is. Even commercial units with driver's have voltage spikes (Ever wonder why some diodes your china array flickers, some people will tell you that's how L.E.D.'s "fire", or that the diodes toast. But really it's most likely driver voltage spikes... Occasionally it can be your house's wiring, big headache...). So all in all, yes, you can safely wire together an L.E.D. array with a good majority of shit around the house (If you got a few quality L.E.D. flashlight's you can even assemble 100% free with around-the-house-items...) For me any kind of project starts with these two rules 1)Keep it simple... 2)GOOGLE is your best-friend (and ICMag!). And my wiring is okay at best, id prefer solder joint's (its a bitch when you pull a wire outta the electro tape...) or wingnut's but I work with what I got... If I had the resource's, my house would look like Umbrella Corporations "The Hive", but full of L.E.D. array's and thousand's of genetically modified krypto-canna plant's
