Well Made - The puck lights are made of high quality aluminum alloy which is much sturdier than plastic shell, aluminum has much better heat dissipation ability, which is good for a longer working life for the LED lights.
Touch Sensitive Dimmer Switch - The brightness of the puck lights can be adjusted from 0 to 100 full brightness steplessly, with the inline on/off touch dimmer, note: can not use existing wall dimmer switch for dimming
