Induction lamp competes with LED on price

14may14FinallyA US company is attempting to compete with LED light bulbs using induction technology.

The Finally Light Bulb Company of Massachusetts makes a lot of claims about the quality of light – for example it has the “first energy-efficient A type light bulb that truly replicates the familiar warm and reassuring glow of the now-banned incandescent bulbs that consumers love and miss”.

And: “The big lighting companies are focused on producing replacement bulbs with LED and CFL technology,” said board member Dr Ihor Lys. “Both are undeniably efficient, but LEDs pose a huge affordability challenge for consumers, while CFLs have a really hard time replicating the quality of light and instant-on performance of the traditional incandescent lamps.”

Forgive me, and correct me, if I am wrong, but aren’t induction lamps essentially fluorescent lamps with the electrodes isolated from the UV-generating gas?

They have long life, and the fill can include materials that would react with internal electrodes, but the output spectrum is dependent on the UV-to-visible phosphor – just like a CCFL.

So I am struggling to think how the spectrum can be any better than a CCFL, unless there is a useful phosphor component that cannot be used in CCFLs due to electrode reaction?

Anyway, this is not to detract from the achievement of squeezing a mains-to-MHz inverter inside the bulb as well as the induction coil and gas envelope – assuming this is what has been done.

And presumably there is something to stop too much EMI getting out.

The company brands its technology ‘Acandescence’ and claims will last 15 times longer than an incandescent, and will retail for less than $8.00 in the US – although recommended price is $9.99.

The intention is to offer them in 60, 75 and 100W replacements. The 60W is expected in July, and the other two in the autumn.

    Thanks Simon.
    It might be a bit tricky to dim too.
    Nice to see a company plough its own furrow though.

    The first thing that strikes me is that the specifications are very similar to current LED lamps, except the lifetime (I assume this is L70?) is about 30-40% of most good-quality LED lamps. Sure the price is much less, but I’ve changed to LED lamps at home because I don’t have to touch them for the next 10 years, and they don’t use glass or any heavy metals that CCFL and many induction lamps use (most people still don’t know they need to use gloves to clean up a broken CCFL lamp) . Other than the price point – and don’t forget LED prices are still reducing at a dramatic rate as volumes increase and technologies of the LEDs and LED drivers improve – I don’t see the reason why induction technology would take off and provide a long term business case.
