专注于LED灯 丝封装的雷盟光电(LeDiamond)日前宣布其Tesla系列灯丝，经由国际第三方检测机构－倍科实验室(BACL)九个月的严 格测试后，成功通过美国Energy Star能源之星对流明维持率(LM-80)的要求。这是雷盟自2013年成功开发Tesla灯丝后的重大突破。
雷 盟表示，Tesla灯丝系列产品，量产规格为白光180lm/W(5700K、CRI 70)，暖白160lm/W(2700K、CRI 80)，采用透明陶瓷为基板，不论在热稳定性以及光通量维持率皆有令人满意的表现，产品目前主要应用于蜡烛灯与球泡灯。此次雷盟光电测试的产品为 Tesla 2903-暖白(2700K)，经由6000小时的50毫安培(mA)实验后，从BACL出具的测试报告显示(参见下表)，数据远优于LM-80在室内住 宅规范的91.8%，与户外及商用规范的94.1%。
