led节能灯作为室内照明灯具的优势未必比普通节能灯明显,但作为电筒、台灯、射灯等只需照射狭小角度的灯具使用时还是非常优秀的
1、LED亮度(MCD)不同,价格不同。用于LED灯具的LED应符合雷射等级Ⅰ类标准。
2、抗静电能力:抗静电能力强的LED,寿命长,因而价格高。通常抗静电大于700V的LED才能用于LED灯饰  
3、波长一致的LED,颜色一致,如要求颜色一致,则价格高。没有LED分光分色仪的生产商很难生产色彩纯正的产品。
4、漏电电流:LED是单向导电的发光体,如果有反向电流,则称为漏电,漏电电流大的LED,寿命短,价格低
5、发光角度:用途不同的LED其发光角度不一样。特殊的发光角度,价格较高。如全漫射角,价格较高。
LED light bulbs for indoor lighting purpose has not significant advantages over ordinary energy saving light bulbs, but they are excellent candidates when used on applications that require small viewing angle, as flashlight, lamp and spotlight.
1.Luminous Intensity: LEDs with higher luminous intensity are more expensive. LEDs for lightbulbs should fulfill (FDA) Laser product compliance level Ⅰ.
2.ESD: LEDs with higher ESD level have longer life time and are more expensive. Usually, only LEDs with 700V plus ESD protection can be used as LED lighting.
3. Consistency of wavelength: price will be higher if color uniformity is required. It’s difficult for manufactures to provide uniform color without putting a spectrometer on the binning station.
4.Reverse current: LEDs are emitters with unilateral conductivity. If there’s reversed current, it’s considered as leakage current. LEDs with high leakage current usually have shorter life time and are cheaper.
5.Viewing angle: Different viewing angles are required for different applications. Special viewing angles and big angles for diffused reflection are usually more expensive
