In all my blogging, I try to also keep an eye toward the environment (and my wallet). So this year, I'm switching to christmas lights made with light-emitting diodes (LEDs). They are 90 percent more energy-efficient than incandescent lights (what you probably have in your Christmas boxes right now), and though they'll cost a bit more to replace up front, the savings in the long-run will be worth it..
Check out Holiday LEDS for a wide variety of lights.
Shopper's Alert: This week, Target has Philips LED USB-powered color-changing tree or battery-operated snowflakes (35-count sets) and LED battery-operated micro string lights for $5. Perfect small strands for door-side trees or wreaths.
Walgreens has 25- and 50-count LED lights buy 1 get 1 free (price is $9.99).
