LED 燈帶 12V 還是 220V

在TB見 LED 燈帶有 12V  同 220V,師兄們覺得那種較安全?

只論安全性當然是12v的安全
但若果你是拉好幾十米的燈帶的話,也只能選擇220v了
一般220v是一米一剪,而12v是5cm一剪
而在長距離架設上,12v的線損理所當然比220v的高多了

12V要買隻火牛罷?220V 用個啲STARTER好似細啲,是否這樣?

220V果D基本上只係加隻Rectifier, 冇咩starter可言
都係DC拖電阻做野

Just bought Philips LED燈帶 at taobao 2 weeks ago, for 1M cost around 120HKD with the all parts including transformer etc. with boxed packing. Very nice I placed it under the Kitchen light and replaced my T5. It is all 12V, one transformer can link to 1-3Meters LED.

Philips got 2 models":  high or low power one as well.
