Yes, they are out already, seems earlier every year! I don't know how much you know about LEDs in general, so I'll briefly address many aspects of the topic, then follow with a condensed listing of sources and types.
LEDs take on average about a half to a tenth (or less!) as much power for comparable light levels with incans, depending on color. The blues are especially striking, being MUCH brighter and more saturated than similar incans. They last practically forever, though you will get the rare defect LED that soon goes dark. The performance/cost ratio has really climbed in the last couple years. Reliability and features have gone up, while price has dropped.
The standby is Forever Bright (put out by Holiday Creations). These are superior in that they have molded bases which (usually) preclude water from corroding the LED leads. (Other suppliers are starting to come out with molded ones as well.) They are available online from various sources (Christmas Treasures, Inirgee, inc (Imaginary Colours), Brite-lite.com, and probably others. The best-known brick-and-mortar sources for these are Costco and Lowe's, though I'm sure others exist, some of which may not yet have put out their lights. Also, it seems Mill's Fleet Farm carries these in 25 and 35-light sizes.
These two stores do not both carry the same products. Costco has multi (which includes a very beautiful saturated fuchsia!), red, and warm white (actually about 3500K) in 100's, while Lowe's has the 25's and 70's in multi and various solid colors. Lowe's offerings include bridge rectification to greatly reduce the characteristic flickering common to LED Christmas lights. (Though this isn't even listed as a feature on the package!) :huh2: Walgreens has some orange Halloween ones. Expect to pay 12 to 15 dollars for 70 to 100 lights. They come in styles such as cone (strawberry) globe (razzberry), traditional (mini ice), and C7 shapes.
Non-molded-base types are giving stiff competition. Living in usually (though not always) dry Tucson, Arizona, I haven't noticed much corrosion on these. This type is generally a bit cheaper, typically costing 7 to 12 dollars for 60 lights, depending on diffuser cover and store. They are available in various colors, shapes, and string lengths at ACE Hardware, Big Lots, Wal Mart, Target, and Sam's Club, and probably others. These often have the same shapes as the Forever Brights, but also come in "Dome", which is the native T 1 3/4 LED package. They are also sometimes available in the T 1 3/4 inverted-dome wide-angle package (Wal Mart and Sam's Club).
Hope this helps! Let me know if you have any other questions! :huh:
