LED 立方體是一款非常明亮的燈光，非常適合用作車輛的探照燈或燈塔頂端的信標。LED 是極性敏感元件，這意味著電流僅朝一個方向流動。如果將電線連接到電池時 LED 沒有亮起，請嘗試反接電線以反轉電流方向。
LED 立方體只是電路的一部分。添加 電池 為您的創作供電，馬達 讓它們動起來，以及 開關 來掌控一切！
Mounted this on the front of my truck as a searchlight and it cuts through fog way better than my old halogen setup. Just remember it's polarity sensitive, so check your wiring before you power it up.
The brightness on this little cube genuinely surprised me — it throws a clean, wide beam that lit up my whole backyard. Wiring it was simple once I remembered LEDs are polarity-sensitive, so it only works one way around.
Mounted this on my truck as a searchlight and the beam cuts through fog like nothing I've used before. Just remember it's polarity-sensitive, so double-check your wiring before you power it up or you'll get nothing.
