According to the website noted in the OP, it looks like the lowest priced, qualifying set for the $3 exchange is $8.97 (yellow or purple 50 ct. string). Prices go up from there. For the $4 exchange, it's $6.98 (a nightlight) or $9.97 for a string of 100 multi-color lights. For the $5 exchange, it looks like $14.97 for various 50 ct sets. Better than nothing, and with a sale or coupon, perhaps even better...

Hmmm....I remember a 100 light string for $1.00 or 1.50 on BF at meijer.
How many hours of use till you break even with these??

LED lights "burn" cooler and last longer than incandescent bulbs. That means less need for air conditioning, fewer visits from the fire brigade, lower insurance premiums, and fewer servants needed for the upkeep of ornamental lighting.

Even taking at face value the statement that LED's use 90% less energy, the information given in that link is off by a factor of ~10. Another site said: The site LEDs run around .05 watts. Incandescent is almost 10x more expensive to run, but about 1/4- 1/2 the price to purchase. Assuming you buy 7 strings with 70 LEDs per string this gets you 490 LEDs for about 105 dollars. 10 strings with 50 incandescent= 500 lamps for about 40 dollars for a initial savings of $65 bucks.
How long will it take the LEDs to recoup that $65 dollars?
LED ( Watt Usage * Hours/Day * Days/Mo. ) / 1000 = Kilowatt Hours used that month
So the savings are $24.00 - $0.23= $23.77 per year.
So you will need to run the LEDs for 3 years to get back the extra $65 bucks you spent on them.

Here is some info I found about 60 Hz flicker with LED holiday lights.
From http://en.wikipedia.org/wiki/Christmas_lighting_technology#LEDs " low-end sets do not contain power supplies (or have only a transformer instead of a SELV), and so the bulbs flicker in sync with the alternating current, being completely off when the voltage is negative. This produces a noticeable stroboscopic effect when an individual happens to move the lights across his or her field of view quickly, as when moving the eyes or turning the head rapidly. Higher-quality strings include a bridge rectifier to supply full-wave direct current to the lamps, making the lights brighter and greatly reducing the flickering (though there is still a small amount because diodes need a minimum voltage to begin conducting). Cheaper sets with two circuits connect each in the opposite polarity, which minimizes flicker in the combined light reflected from walls and also keeps power consumption symmetrical so as not to affect the electrical system." ... "One drawback discovered to this technology for outdoor lighting, at least in North America, has been that squirrels have been found damaging them. The species must wear down their continually growing incisors by gnawing on hard objects. They apparently find the diode's durable plastic construction useful for this need, while its low power consumption means a minimal chance of electrical shocks to discourage them. Animal experts have suggested leaving edible hard nuts on the ground around lighting fixtures to distract the rodents with food that can also serve the same dental needs."

Question: Do any of the GE LED holiday light sets incorporate a transformer or bridge rectifier to reduce flickering caused by AC power? If so, which light sets?
We manufacture two types of LED lights - Energy Smart which is full wave rectified and StayBright which is half wave rectified.
