LED Lightbulbs - super efficient light bulbs

  • Thanks Guyz! Thanks sa mga input and ideas ninyo!
  • Although the lamps market will bring in an estimated thirty-eight billion dollars this year, L.E.D.-bulb makers are already reacting to the spectre of declining sales. One response, echoing the path of incandescents, is the emergence of cheaper bulbs with shorter life spans. Last year, for example, the lighting-industry giant Philips introduced a sixty-watt, ten-thousand-hour L.E.D. that sells for five dollars. But a profusion of new manufacturers, most of them in Asia, has driven cost and quality much lower than that. (California is the only state in the federation with a minimum-longevity standard for L.E.D. lamps—ten thousand hours, effective January 1, 2018.) “You can buy bulbs on eBay that are of such low quality that, when you screw them in, you can actually get a shock,” Hoelzenbein said. He’s heard reports from China of people buying bargain L.E.D. light bulbs by the kilogram, knowing some would last and others might not work at all.

    is it a conspiracy? or is it just giving in to the demand of poorer consumers who want a lower initial cost even if it means higher long term cost? In the philippines you call that the "tingi" mentality.

    Probably is... not only LED bulbs, but also some stuff that needs batteries which are manufactured at a lowest cost, but not only Philippines or rather poorer consumers rather risk of buying these kinds of low quality products which may leads to certain hazard

    Back to Cheaply made LED bulbs... some of them won't last a day let alone the night you purchase it, some would die out because of slight electrical surge but usually the major reason is insects... if any insects gets in to the driver board and they got fried in the process and the bulb too will die out

    Unlike some mid to high end brands they know the issue and at least they cover the driver board or rather separate from LED unlike the cheaper ones that the LED and driver are on one board
  • More variety, more options - more sales, I suppose (Samsung strategy)
    Can you still find LEDs that cost more than 400Php a piece or more? I mean Philips is now in the market and they sell for less than 300Php each
    Even less than 200Php, too for some E27 standard bulbs.
    My bulbs cost more than 700Php each 6 years ago. I now have low cost GU10s that are more than 2-years old

    So far, the more than 6-year old bulbs are still going strong despite being on for more than 8hrs a day (at night)
