Professional Electrical Repair and LED Christmas Lights
Why is electrical repair, unlike house repair, better left to professionals, such as those who have undergone contractor CE, electrical continuing education, or any electrical training course? Here are four good reasons why:
1. Dangerous. Unlike patching up a leaky roof or repainting a water-stained wall, both of which you can happily redo even if you make a major mistake, electrical repair is unforgiving: a major mistake could be your last.

2. Complicated. There are more regulations attached to an electrical wire than there are regulations governing an entire plumbing installation. The codes are compiled in a tome called the National Electrical Code, the bible of all electrical engineers, electrical contractors, and electricians.

3. Expensive. It is expensive. That is, if you make a mistake (presumably, not a fatal one). A lumpy wallpaper you can always rip off; a short circuit can rip you off big time.
4. Thankless. If the repair does not involve the proper operation of the TV or the PC, do not expect the rapturous reception that a successfully unclogged toilet drain gets.
For less than the four reasons above, a reasonable DIY guy will more likely than not engage the services of an electrician or an electrical contractor.

Now, ever wonder what is better, old-style incandescent Christmas lights or the new LED Christmas lights? If you ask an old hand, say an old Sparky who already has three or more electrical continuing education certificates under his utility belt, the answer might be something similar to what a poster said in one of the electricians’ forums: “To tell the truth, I hate Christmas lights. They are the dumbest things I have every [sic] seen. I liked the old style where even if a light bulb burned out, the string would work.”

At any rate, LEDs are coming to town this Christmas.

• LEDs are energy savers. They consume 3 to 33 percent less power than incandescent light bulbs. That’s a saving of $10 every 300 hours.

• LEDs last longer than incandescent bulbs. They’re not likely to burn out before 4,000 hours. Incandescent light bulbs, on the other hand, burn one or two out per strand before 2,000 hours.

• LEDs are cool, literally cool. That’s a great holidays plus, given that 14 people a year die because of Christmas-tree fires.
• LEDs and incandescent light bulbs have the same initial cost—about seven bulbs per dollar.
