天花灯是一种具有高贵档次的一种照明及现代装饰灯具，非常适用于商场超市、酒店、珠宝柜台及高档现在市面上一般都是卖30元左右的，质量好一点的，价格相对会比较贵一点的，性价比不同价格也是相对比较不同的，还有牌子也是相对比较重要的，主要还是看自己的选择

大功率led天花灯是采用导热性极高的铝合金及专利结构技术设计生产的新型天花灯。，要12.钱一个。LED天花灯主要优势在于低碳节能，安全环保，寿命长，完全适应了全球节能减排，低碳生活趋势。是现代高照家居理想选择。灯具在正常使用情况下能达到50000H 相当于50支白炽灯寿命。

大功率LED是指拥有大额定工作电流的发光二极管。普通LED功率一般为0.05W、工作电流为20mA，而大功率LED可以达到1W、3W、甚至数十瓦，工作电流可以是几十毫安到几百毫安不等。所以如果是用1W、3W做的灯具都叫大功率。要想找好的led天花灯，我推荐你去淘宝搜索-确实美led天花灯。价格一般在1-2元

你好，每个厂家生产的天花灯价格都不一样，一般是几十元，我家里购买的是鸿恺牌子的，几年了现在还没有坏。希望我的回答对你有帮助。

大功率led天花灯一般在60元左右，大功率led天花灯的优点： 1.发光效率高；白炽灯、卤钨灯光效为12-24流明／瓦；荧光灯50～70流明／瓦；钠灯90～140流明／瓦，大部分的耗电变成热量损耗； LED光效经改良后将达到达120～200流明／瓦，而且其光的单色性好、光谱窄，无需过滤可直接发出有色可见光。 2.耗电量少 LED*功率0.03～0.06瓦，采用直流驱动，*驱动电压1.5～3.5伏，电流15～18毫安，反应速度快，可在高频*作。同样照明效果的情况下，耗电量是白炽灯泡的八分之一，荧光灯管的二分之一。 3.使用寿命长采用*光场辐射发光，灯丝发光易烧、热沉积、光衰减等缺点。
