Ironically Sam's Club and Home Depot didn't have very good prices on LED light sets compared to even WalMart itself. I think even Lowe's have them cheaper.

posicat said:It all depends on how the strand is wired.
You could have a strand of 100, but in actuality it's 4 strands of 25 put together. That keeps the brightness the same. I wasn't thinking about the drain/dimming but rather that each LED light in a C6 strand might be the same brightness rating (watts) as the ones used in an LED mini light set. Same brightness LED but a bigger plastic 'bulb' to light might make them look dimmer even though each bulb gives off the same amount of light really. twas a good point about looking for offwhite LEDs earlier btw. IF someone doesn't like a color they should look for a different color. |

I noticed that the LED Christmas strings at Lowe's are much brighter than the ones sold at Costco this year. The Lowe's ones cost twice as much though but they are as bright as the incandesent ones but my judgment. |

I will be checking this out this weekend I need to buy x-mas lights for my new house and LED is the geekiest way to go. |

I just want to second that there are two types of white bulbs, standard and "soft white". The soft white versions, when available, are just like incandescent in color. The standard are a little harsh looking in my opinion. So note that when looking. Sams has 180 bulbs for $18, likely three strings of 60, and they have some in solid colors like blue and red. |

I've used these Costco LED's the last 2 christmas. I strung about 4 of these for a total of 400feet to ring around my outdoor 30+ feet pine tree. They are not as bright as similar size regular lights but when it's dark outside it doesn't really matter. In fact they give off a truer color, ie reds being more red and green being more green when compared to regular bulbs. I think they were twice as much when I bought them so they must have come down in price. |

It pays to check LED Christmas lights fairly closely to make sure you're getting what you want. LED technology has evolved by Leaps and Bounds in the past year or two, and the reason prices are be dropping so much may be because some manufacturers are using old (read: not so bright) LED technology in light strings. LED light strings should be a lot more durable than incandescent bulb strings. State-of-the-art LEDs are now so bright in some cases that they're replacing strobe lights in police car roof lights and replacing bulbs in traffic signals. It won't be long before regular household light bulbs start becoming available with LEDs in them instead of wire filaments (which will be great provided the color temperature is OK because they'll last an insanely long time and will use a fraction of the energy of an incandescent bulb). |

There are higher wattage output LEDs now than there were a few years ago but that's kinda irrelevant since these aren't 5watt LEDs like you'd find in a tactical flashlight. There have however also been improvements in efficiency of LEDs also but again I doubt anyone's using anything particularly highend in 10-20 buck strands of small LED christmas lights. Bottomline, look at a display and if you like them buy them. If you're in a nice store , ask them if they'll let you plug them in (politely say you won't take them out of the box, just plug the cord in). I'm confused why anyone would be buying christmas lights to light up a yard or something anyways.... to me Christmas lights should LOOK GOOD. As long as they have good colors and are easily visible themselves that works for me. If you want to light up your yard buy a spotlight. |

lzpoof said:vibe said:Does anyone know if led xmas lights can be dimmed with a dimmer?
no LEDs/fluorescents should be used on a dimmer unless they specifically say they can be. I've yet to see any LED xmas lights that said they can be. If you want to examine my statement a little...... look up the voltages required for different LEDs online. I'm not sure what kind of power circuitry these things have in it but varying the voltage input can have strange effects on lights or none at all. A lot of LED flashlights have circuitry designed to keep a steady current going through them til the batteries die so if your set had a circuit like that , then dimming them would do nothing. Not syaing it's likely your set would have it but who knows. Also, according to everything I've read different color LEDs have different voltage ranges for operation and different minimum voltages they will run at. So while you're dimming your multicolor set thinking about how cool it is to have the blue ones dimmer.... don't be surprised if say the red ones just go out while the blue ones stay lit. LEDs dim because of voltage variations (battery draining) , they are not intended to BE DIMMED as they have a certain voltage range only where they will work..... as opposed to filament bulbs which basically stay lit somewhat at any voltage. Now fluorescents on the other hand.... they shouldn't be used on anything but a power outlet period. I even tried them once on a APC UPS in a power outage and ended that experiment quickly. Apparently whichever of a stepped power curve or straight sin curve my ups was putting out, they didn't like. |

Not bullshitty, just stuck back in 1999. LEDs have been used in traffic signals since the early 2000's. And regular household light bulbs are already widely available with LEDs in them.

Welcome to the 21st century, JonesBeach. LED spotlights and parking lot lights make a lot of sense.... not incredibly high brightness needed for the density (like say a ballpark's lights), hard to reach locations, sometimes harsh temperature/weather changes, and use less power. |

I guess Lowe's is out of stock!  . |

posicat said:LED's are capable of being dimmed, I've dimmed mine with an X10 module as well as on an electronic project bench. LED's can run at any voltage that's at or lower than their specifications without problems.
Fluorescents have problems with dimming because they use electronic circuits that oscillate and boost the output power to the tube to high voltage to make it glow. LED's don't need that.
LED's however do have a different power usage than incandescent bulbs, so they may dim earlier, or later than a string of incandescent bulbs if plugged into the same dimmer. I was thinking the same thing... |

CuriousGeorge said:This makes that firemans invention on that show obsolete, since these LED xmas lights will never be a fire hazard due to hot bulbs igniting dry tree leaves/needles/branches.
Haha, i betcha he didn't see this coming! By next xmas, i have a feeling these will be the only type of xmas lights WalMart/target sells. There's also the very serious issue of shorting and sparking which is maybe just as likely with LED christmas lights. As they get placed and removed over and over things get loose. I've seen more than a lot of exposed wire when looking at lights. Personally I've never seen any heat issues or sparking from christmas lights, that doesn't mean it doesn't happen. Didn't mythbusters address both these issues?

Was this part of a price mistake? Has anyone been able to get these prices recently? I just got back from my Costco and the prices were $13.99 and $14.99. About $4 more expensive than the OP. Perhaps I'll try another one. |

I went to a different Costco, and the colored LEDs were $9.39 but the white ones were $13.99. Oh well. Looks like prices on these vary quite a bit by store. |

I bought a bunch of these (multi-colored LED's) in 2005 after Christmas at COSTCO for $3.97 a set. If you don't need them.... it pays to check, last year they marked them down on Christmas eve, I think they only has red though..... |
