1.LED亮度LED灯具的亮度不同，价格也会有所不同。灯杯：一般亮度为60-70lm;球泡灯：一般亮度为80-90lm。注：1W亮度为60-110lm3W亮度最高可达240lm5W-300W是集成芯片，用串/并联封装，主要看多少电流，电压，几串几并。1W红光亮度一般为30-40lm;1W绿光亮度一般为60-80lm;1W黄光亮度一般为30-50lm;1W蓝光亮度一般为20-30lm;LED透镜：一次透镜一般用PMMA、PC、光学玻璃、硅胶(软硅胶，硬硅胶)等材料。角度越大出光效率越高，用小角度的LED透镜，光线要射得远的。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。白光分暖色(色温2700-4000K)，正白(色温5500-6000K)，冷白(色温7000K以上)欧洲人比较喜欢暖白红光：波段600-680，其中620，630主要用于舞台灯，690接近红外线蓝光：波段430-480，其中460，465舞台灯用的较多。绿光：波段500-580，其中525，530舞台灯用的较多。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。6、寿命不同品质的关键是寿命，寿命由光衰决定。光衰小、寿命长，寿命长，价格高。7、LED芯片LED的发光体为芯片，不同的芯片，价格差异很大。日本、美国的芯片较贵，台厂与中国本土厂商的LED芯片价格低于日、美。8、芯片大小芯片的大小以边长表示，芯片尺寸一般为：38-45mΩ，大芯片LED的品质比小芯片的要好。价格同芯片大小成正比。9、胶体普通的LED的胶体一般为环氧树脂，加有抗紫外线及防火剂的LED价格较贵，高品质的户外LED灯饰应抗紫外线及防火。
