先日、3つあるスポットライトのうち、一つの電球が切れたのでLED電球を導入。
暗いんじゃないかと思われがちでしたが、そうでもなく明るいのでびっくり。
スイッチ入れた時の点灯も早かったしね。

ちなみに使っているのは前述の通りパナソニックのEVERLEDSです。
一般家庭用のモノで口金がE17なのはこれしかないのです(東芝のは業務用らしい)。 

そうこう言っているうちに二つ目のライトの電球が切れた。
明日、もう一個買うかなんて言ってたら買うの忘れて部屋はまだ暗いまま。

Visible Light Solar Technologies today announced that seven new distributors have joined the company’s nationwide network of authorized resellers of the Vector retrofit LED/solar lighting product line.  The expanded network of experts will help customers evaluate their existing energy intensive installed base of lighting fixtures and then retrofit them with Visible Light Solar’s ENERGY STAR® compliant LED and solar/LED lighting fixtures.  Additionally, partners will assist customers in leveraging all tax credits and federal recovery funds available for retrofitting or energy reduction installations. 

Visible Light Solar is the first commercial and industrial lighting company to integrate LED lighting devices with solar power technology.  The company’s LED and solar/LED lighting applications operate 75-85% more efficiently than their HID and high pressure sodium counterparts.  In addition to dramatically lowering energy consumption, Visible Light Solar’s solutions also reduce maintenance costs (LED’s last up to 50,000 hours and are resistant to thermal and vibrational shocks) and produce true-color, programmable illumination. 
 
According to Dee Dennis, CEO of Visible Light Solar, “These companies are at the forefront of lighting and energy innovation and critical to helping customers identify, install and maintain the next generation of highly energy efficient lighting solutions. We are pleased to have them on board as partners, helping customers save money by reducing energy operating costs, as well as lowering the carbon footprint for businesses and organizations around the country.”

Leipzig - In Ampeln, Autorücklichtern und Scheinwerfern sind sie bereits fester Bestandteil - nun sollen die LEDs auch die Glühbirnen zu Hause ersetzen. Das Verbraucherportal www.preisvergleich.de berichtet über die Vor- und Nachteile.

Stiftung Warentest stellte beim Heimtest Enttäuschendes fest: Die LED-Lampe leuchtet längst nicht hell genug. Da sie sehr hitzeanfällig ist, kann sie nur mit wenig Strom betrieben werden. Ohne eine effektive Kühlung gibt sie frühzeitig den Geist auf.

Doch wie hell leuchtet die LED-Glühbirne eigentlich? Helligkeit wird in Lumen gemessen. Die hellste LED erreicht nur 170 Lumen. Eine gewöhnliche 25-Watt Birne schafft 190 Lumen....

Amazing presentation by Paul Debevec demonstrating the technology behind digitally constructing a human face. Photographers take note on how the lighting on the face was used here.

Using a face-scanning sphere with 156 white LED's to light her face to ensure perfect lighting. They used polarizers to block the specular light reflected off of her face.

They turned the polarizers to get the specular light to show the texture of the face (skin pores and muscles...etc.) to create the mold/map of the face which is used to make animating the face as real as possible

The system used in that presentation is called Light Stage 5. You can see another demo here of Light Stage 6 here
