    How to Understand LED Lights:

    • Compare LED lighting to compact fluorescent bulbs. Compact fluorescent bulbs are not as efficient as LEDs, they take longer to light up and they contain mercury. LEDs contain no toxic elements. And, according to Amber Angelle, writing for "Popular Mechanics," LEDs are one of the most promising light sources out there in terms of efficiency, longevity and reliability
    • Figure the cost benefits. LED lights are more expensive initially, but after five to 10 years, homeowners recoup the costs. As of 2010, an outdoor LED spotlight runs you about $100 compared to $7 for a regular light spotlight bulb, according an article by Elisabeth Rosenthal and Felicity Barringer in "The New York Times." But, scientific advances are happening monthly, Brian Owen, a contributor to the LED trade magazine, said in "The New York Times." These advances are sure to bring the prices down. One advance is growing LEDs on silicon wafers instead of the more expensive sapphire, like what is currently occurring
    • Contrast how much longer LED lightning lasts than incandescent bulbs. You'll find LEDs last so much longer that it changes light bulbs from cheap, disposable energy-wasters to semipermanent fixtures in your household. LED lights can last 22 years. They are, basically, an install-and-forget type of purchase. Compare LED lighting to a fluorescent bulb that might last you 3,000 hours. The LED lasts more than 100,000 hours, according to Rosenthal and Barringer. Angelle estimates that LEDs can last for 50,000 hours
    • Convert to LED lighting, and you can decrease carbon emissions from electric power lighting by up to 50 percent in 20 years, according to Rosenthal and Barringer. This type of conversion would be, perhaps, the most cost-effective approach to tackle wasted energy
    • Program the LED lighting to perform tricks. They can get brighter as someone walks under the light, or they can flicker to guide paramedics to an emergency at your house. And, because LEDs do no emit ultraviolet light, you can sit outside on your patio in the summer without LEDs attracting bugs

    • The photos below were taken in a dark room, without pre-setting the camera or editing the photos afterwards
    • Different colour temperatures of the LED bulbs can be seen on the trim of the terracotta pot and on the cactus
    • The first photo the object was illuminated with cool light. The cool light is the brightest
    • The second photo natural white was used, it is similar to sunlight
    • The third photo the warm white can be seen, which is similar to the color of tungsten lighting and halogen lights

    The Kelvin Scale:

    Colour temperature has important applications in lighting. The colour temperature of a light source is usually measured in kelvins (K) at which the heated black-body radiator matches the colour of the light source is that source's colour temperature 

    4W LED Bulb

    • Higher colour temperatures (5000 K or more) are "cool" (green-blue) color, and lower colour temperatures (2700-3000 K) "warm" (yellow-red) color

  • Other Thoughts: I bought these lights a few weeks ago to put outside since I do not have easy access to electricity. I charged them first for one day, and they have worked great everyday since then getting their daily charge from a mostly sunny spot. I love the blinking setting.

  • Other Thoughts: They're gorgeous! Luckily, we've had a warm winter so the ground wasn't frozen, (that's the only problem I could see for install). I did it alone and at 10:00 at night - it took about a half hour. I'm so happy with the starry, sparkly look they've given our yard.

00:00:00 12-28-2010 Just Awesome Overall:  
  • Other Thoughts: I know for sure they go for at least 8 hours but I haven't gotten up to see what time they go out in the morning. They seem like the bulbs are very small but they put out a good amount of light for their size. Not sure what else to say, they work and look good maybe after some time I will have an idea of durability but for now they work just fine.
