LSG Unveils $30 60-Watt Equivalent LED

Today Lighting Science Group announced that it has become the first U.S. company to domestically manufacture one million LED bulbs in less than a year.  With the announcement, LSG also unveiled a new omnidirectional A19 LED bulb as the one-millionth bulb.  The 60-watt replacement is 75% more efficient than an incandescent bulb and dimmable, mercury-free, and relatively affordable.

The bulb will be available in January for less than $30.  Assuming six hours of use every day all year long with an average utility rate of $0.10 kWh, the new LED is supposed to have an energy savings payback of less than two years, according to an LSG press release.

The Definity LED has an output of 850 lumens, uses 13 watts, and lasts up to 50,000 hours, beating the competition in these areas and in price by about $10.

That said, one thing to keep in mind is correlated color temperature and color rendering performance.  I don’t have these numbers for the new A19 LED and will update this article upon obtaining the information from LSG.

As prices continue drop, the economic case for LED lighting becomes more and more undeniable, even for folks that don’t like the initial cost.  A light like this would only need to be changed every 23 years or so, depending on use and other factors, so there’s also the convenience factor to consider.

If you’re looking for help in reviewing the numbers associated with high-performance light bulbs, Lighting Facts is a great resource.  The site has a Lighting Facts Label that explains lumens, lumens per watt, color rendering index, correlated color temperature, and Kelvin temperatures, etc.

    My electric company subsidizes fluorescent bulbs – 99 cents each. They also recycle them to capture the mercury. And LEDs use the same amount of electricity as fluorescent bulbs. So, why do I want to spend $30 for an LED instead of $5 for 5 fluorescent bulbs?

      Because the CFL bulbs contain Mercury that will be killing the planet in the long run while costing you more to run.

        A propos of Blake’s comment above, do LEDs use the same amount of electricity as fluorescents? I thought they used much less. Otherwise, why would they cost more to run?

        • lawrenanne

          less to run, that is.

    These were to have been available by Jan ’11, but still no sign of them on store shelves, online retailers, or even the company website. They look nicer than the Philips 60w-equivalent LED currently available, and are $10 cheaper to boot. The recent, tragic passing of LSG’s CEO has probably caused schedules to slip. I hope they get these in production soon. Cree’s 60w replacement LED looks to be even nicer (I’m impressed with their CR6 downlight, which shares the same basic technology), but it’s just a prototype with no mention of an expected production date, much less being on the shelves at retailers.
