Bulb melting socket. Socket or bulbs fault?

hey guys i recently got these http://www.tmart.com/E27-Hanging-Lamp-holder-White-Dark-Red_p166509.html to hold my bulbs as it worked much better with my pc grow box setup. I just plugged my bulb in to the socket to test it it out, left it for about 20m and came back and the bulbs base was all melted around the sides and the room stunk of melted plastic. http://www.amazon.com/dp/B001AZOV9K/ref=pe_385040_30332190_pe_175190_21431760_M3T1_ST1_dp_1 This is the bulb I had plugged into it.
Ive got two more of these already in the mail, and was hoping someone could let me know if there is some sort of problem between this socket and bulb? Or maybe that this is just a bad quality bulb. The socket still works on my other light bulbs, but the bulb no longer works.
Thanks for any help

jeesnh that is a worry. The only way to find out is to use another type of bulb with same wattage in the socket. My guess would be that the bulb is just to hot for that socket. This should not happen though, but a big worry for you i am sure. good luck.
