Fifty feet on the 100 lite box.

How do you hang these up--do they come with clips? I've got rain gutters all around. Thanks.

1) The box on Costco's C6 multicolored bulbs says they take 4 watts. I just tested them using a Kill-a-watt AND a UPM EM100.

Here are the results:
Kill-A-Watt: 2 watts
UPM EM100: 2 watts > sometimes at 3 watts > returning to 2 watts

2) The box on Costco's MINI multicolored bulbs says they take 4 watts. I just tested them using a Kill-a-watt.
Here are the results:
Kill-A-Watt: 2-3 watts (3 watts sometimes > 2)

3) The box on Costco's MINI *WHITE* bulbs says they take *8* watts. I just tested them using a Kill-a-watt.
Here are the results:
Kill-A-Watt: 3-4 watts (straight 2 watts)

 

My favorite is the C6 bulbs. Overall the best performance, best price, with the least electricity.

 

There you have it. A rundown of all of Costco's LED bulbs. Personally, I'm not a fan of the mini whites. The mini colored are OK, but the colored C6s are my favorite.

They are rated on the box as if the lights were on 100% of the time. LEDs are diodes so they only allow current in one direction. Since our 120V AC is a sine wave, when the current is heading back in the other direction, the lights are actually OFF. Thus, the lights are only on 50% of the time which is why the register 2W instead of 4W. Since they are "flickering" at 60hz, most people can't notice them turning on and off real fast. If I move my head while looking at the lights or move the lights around while looking at them, I can see a slight flicker.

The costco in my area (Southwest Ohio) is clearing these bulbs out. The mini white are $4.97 now and the C6 are $3.97. For some reason the mini colored are still full price.
