Cree发布色温2800K显色性指数91的灯泡
功耗9.5瓦，光效102流明/瓦，光通量969流明，相当于65W的白炽灯。尺寸规格应该和A19白炽灯泡相同。

Cree Demonstrates Record-Breaking LED Light Bulb
DURHAM, N.C., OCTOBER 29, 2009 — Today, at the annual Cree (Nasdaq: CREE) shareholder meeting, Cree Chairman and CEO Chuck Swoboda demonstrated an A-lamp LED light bulb with the highest lumen output and efficacy reported in the industry. The bulb produces 969 lumens at an impressive 102 lumens per watt, which is the light output equivalent to a 65-watt incandescent bulb, yet it uses only 9.5 watts.
The demonstration A-19-style bulb features the latest Cree production XLamp® XP-G LEDs and TrueWhite Technology, a patented method of delivering warm-white light with superior color rendering and efficiency. It delivers a 2800 K warm-white light with a 91 CRI. All data was verified by third-party testing under steady-state operating conditions.
“We are pushing the industry by demonstrating what’s possible,” said Swoboda. “With every improvement in LED components, new applications become achievable. We are excited to show the world not only what can be done, but what they should expect in an LED light bulb.” Cree开始进入家用照明领域了，不知道这灯泡的成本如何 估计用5年普通灯泡的电费加起来还不够买的。 看不懂鹰文 t5 28w 也差不多105lm/w 价格实在不亲民 LS的！谁每天能点8小时灯泡呢？ 不错，不知道什么时候能普及！ 不错，不知道什么时候能普及！ led显色性真的不说了，看起来很不爽 省的电费钱，估计不购买灯泡 平均一天点8小时，整个晚上都过去了。我看开开关关2h差不多 除了省电费，还省灯泡钱，普通灯泡容易烧坏 能省电，能省钱麽？ 看来现在LED还只能在廉价小功率和专业范围里混啊 省电是不假，貌似成本比省的电费要贵。。 每天8小时的灯泡，电费65×8/1000
这样算。。。。。200天多就打平了
