The Super Bright LED
Posted March 17th, 2007 by Marius Trusculescu
With all the controversy regarding the banning of the incandescence bulb due to environmental issues, more accent has been put on alternatives. Today Siemens unveiled such an alternative in the form of Ostar, a small LED (light-emitting diode) with an area of just 1 square millimeter capable of delivering unprecedented brightness at 1000 lm (lumens).
As consumers might not be well acquainted with the lumen measurement unit, Siemens made a comparison “a 50 Watt A 60-watt light bulb emits 730 lm, while a 50-watt halogen lamp has an output of approximately 900 lm“. So it delivers
enough brightness to light a room, but with impressive energy savings. For example the Ostar Lighting LED produces 75 lumens for each watt it consumes. Comparing this with the 730 lm emitted by a 60 watt light bulb we get around 6 time less electricity consumed for the same amount of light. Also such an LED lasts 50 times longer than incandescence light bulb and 10 times longer than halogen products.
However there is a downsize for this type of products in the initial price. They usually are way more expensive than the two usual products in our homes. It is true that we yet know nothing on the pricing for the new LED, and there is not even an estimated launch date but this high efficiency solutions will have huge impacts on power consumption.

The LED module is from OSRAM - *not* Siemens. That’s a gross error but not the only one.
The numbers in your story are completely fabricated and don’t align with the actual specs of this product. You will find the lumen per wattt ratio much lower than you claimed and in fact not even at the levels of an entry-level CFL luminaire.
1 LED is not going to light a room. It would require a luminaire made with multiple modules to achieve that. BUt you won’t want to know the price of such a product at this time nor will you want to know the energy consumption or thermal properties.
Maybe in 5 to 10 years LED production and technology will be whhere it’s needed for general and residential lighting applications instead of just specialty products such as flashlights.

Dear Bob,
you should know that the OLD bright LED had the OSRAM http://www.osram-os.com/ostar-lighting/index.php?lan=eng
This one is a Samsung and the figures up there are real, nothing fake!

Here is the link to the original press release from Siemens.
Regarding the Siemenes-Osram dispute you should know that in 1998 the two companies signed an agreement regarding co-developing LED light sources and this product is one of the results of that collaboration. (Actually OSRAM is part of the Siemens AG but from what I know they maintain some independence over the mother company)
