And this just in: "Osram has developed a small light-emitting diode spotlight that achieves an output of more than 1,000 lumens for the first time. That's brighter than a 50-watt halogen lamp, thereby making the device suitable for a broad range of general lighting applications. The Ostar Lighting LED, which will be launched on the market this summer, can provide sufficient light for a desk from a height of two meters, for example. Its small size also enables the creation of completely new lamp shapes."

"An innovative LED lamp named Pharox has been launched in the Netherlands. Apparently, this 3.4 watt bulb is a serious replacement for a 40 watt incandescent bulb. It is rated at 60 lumens per watt. It is also more eco-effective when compared to other LED lamps, because the production does not include phosphor. The bulb will initially be available to customers of the green energy supplier Oxxio (the price listed is € 22.68 for 4 bulbs)." http://www.treehugger.com/files/2007/02/new_led_lamp_ph.php On 2/22/07, Bruce Metcalf <[EMAIL PROTECTED]> wrote: > Eugen Leitl wrote: > > On Wed, Feb 21, 2007 at 09:54:12AM +0400, Ramakrishnan Sundaram wrote: > >> Bruce Metcalf said the following on 21/02/2007 07:29: > >> > >>> I must have more sensitive radar.
