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.
