bots 8 Posted October 12, 2011 Press Room Cree 231 Lumen Per Watt LED Shatters LED Efficacy Records High-Power R&D Result Sets Record for Solid-State Lighting Industry Cree Continues to Lead the LED Industry, Demonstrates Most Efficient LED DURHAM, N.C., May 9, 2011 — Cree, Inc. (Nasdaq: CREE), a market leader in LED lighting, reports another industry-best efficacy record of 231 lumens per watt for a white power LED. This result is a significant advance beyond Cree’s previous industry record and further demonstrates how Cree’s relentless innovation continues to push the boundaries of what is possible with LED lighting. Cree reports that the LED efficacy was measured at 231 lumens per watt using a single-die component at a correlated color temperature of 4500 K. Standard room temperature 350 mA testing was used to achieve the results. “It wasn’t long ago when 200 lumens per watt was considered the theoretical maximum efficiency for a lighting-class LED. We broke that barrier in 2010, and have now achieved 231 lumens per watt,” said John Edmond, Cree co-founder and director of advanced optoelectronics. “The innovation from our labs is the foundation for our industry-leading XLamp® LED family and an invention that continues our leadership of the LED lighting revolution.” This R&D result features advanced aspects of the same technology used in Cree XLamp white LEDs. Cree believes higher-performance LEDs can enable new LED-based applications and drive down the solution cost of current LED-based designs. While this level of performance is not yet available in Cree’s production LEDs, Cree continues to lead the industry with the broadest family of high- Het waarschijnlijk nog wel ff voor dat hij op de markt komt. Weer een goede stap in de goede richting Greets bots Quote Share this post Link to post Share on other sites
Donnie 19 Posted October 12, 2011 LED is nog niet volledig door ontwikkeld. Planten houden wel van stralingswarmte, met name in de bloei. Vandaar dat een scrog opzet per definitie beter is als een SOG als je deze soort lamp boven je planten hangt. Het groeien van stekken onder LED gaat waanzinnig snel in ieder geval. 4 Dagen later (onder circa 104 watt LED) Groet, Donnie Quote Share this post Link to post Share on other sites
Stikkie 2.0 4 Posted October 12, 2011 bij een sog is het net zo belangerijk dat je het veld gelijk houd als bij een scrog...! En dan maakt het ook geen verschil... Maar ik snap wat je bedoelt hoor.. Mvg stikkie Quote Share this post Link to post Share on other sites
