Of course, the answer is porcelain lamp holder. But the ceramic lamp holder is not easy to transport, it's fragile easy to break, it's heavy, the cost of transportation is high. Bakelite lamp holder is not environmentally friendly, Unrecyclable. High temperature resistant 180-250 and expensive cost, High temperature porcelain lamp holder, ceramic lamp holder temperature higher than 3000 degrees, bakelite lamp holder temperature of 180 degrees, 10 minutes to burn out.

Generally speaking,the incandescent lamp and metal halide bulb are direct heat radiation lamps, a 220 volt incandescent lamps common maximum power of 300 watts, metal halide lamp can up to 2000 watts, the light bulb is at very high temperatures! So the lamp holders must high temperature resistant! But commonly used bakelite lamp holder in the bulbs power more than 150 Watt,it's often burned out! So need to choose a porcelain lamp holder.
