The new Ultra LED A-Line lamp will consume 12 watts and give off 810 lumens, almost identical to Philips’ bulb. Like that model, Sylvania’s light bulb will last 25,000 hours, be dimmable and be made available in late August.
Color temperature clocks in at 2700K, appropriate for everyday lighting, Sylvania said.
The company did not offer pricing for its new product.
Philips and Sylvania weren’t the only ones to introduce a new LED bulb this week:
- On Thursday, Lighting Science Group introduced its Definity A19 60-watt equivalent bulb, which offers 770 lumens from a draw of only nine watts.
- On Wednesday, Lemnis Lighting introduced its Pharox 500 40-watt equivalent LED bulb, which offers 500 lumens for less than $40.
- On Wednesday, General Electric introduced its 40-watt equivalent Energy Smart bulb, which offers 450 lumens from a draw of nine watts.
- On Tuesday, Home Depot introduced its 40-watt equivalent EcoSmart A19 bulb, which retails for less than $20.
As I’ve written before, LED light bulbs are a welcome improvement to lighting technology and offer mercury-free operation. But they’re quite expensive, with previously-announced models (see links at bottom) listed at roughly $50 each.
The good news? Haitz’s Law. Martin LaMonica notes on CNET that the law stipulates that the cost per lumen falls by a factor of 10 every 10 years at the same time that light generating power increases by a factor of 20.
All of the new bulbs were announced at the 2010 LightFair International show in Las Vegas, Nevada.
