New LEDs Shown Off By Lighting Science Group

GE and Phillips weren’t the only major players to roll out spanky new LED bulbs at Lightfair International this year – also in the mix was Lighting Science Group, which debuted its Definity LED bulbs, which it bills as both long lasting and low-cost (which certainly cannot be said for every LED bulb).

The Definity line of LED bulbs – which now include LED flood and spot lights as well as vanity lights and 60 and 40 watt equivalent omnidirectional bulbs – are approximately 75-80% more efficient than traditional incandescents. They are also dimmable, “instant on”, and (like all LEDs) are designed to last for decades.

Additionally, Lighting Science Group cites independent tests that attest to the lumen (light) output of these bulbs as outperforming many comparable LED bulbs products by 25-30%. Definity bulbs are also available in a number of different colors.

While James Haworth, chief executive officer of Lighting Science Group, stated that these bulbs offer “quality and energy savings at an affordable price,” there has been no word yet on their actual price.

    Not just a price problem with LEDs…nnnLEDs – like CFLs before them- have nrecently been found to have serious homenbreakage and disposal concerns, nhaving lead, arsenic and toxic vapor content,naccording to University of nCalifornia (Davis and Irvine) researchn suggest nu00a0wearing safety protection when LED breakage occurs andnthat the bulbs should nbe u00a0recycled.nnThey also maintain that there was insufficient product ntestingnbefore LED bulbs came onto the market. There was a law that was nsupposednto take effect on January 1 that would have mandated such testing, nbutnit was opposed and blocked by industry groups, and has been put u00a0on nhold…n

    LED lights are the way forward, hopefully the price of these models will be competitive.
