Don't be afraid Brad!
Just hold firmly onto the plug end of the bulb and pull the female portion away from the bulb. Four prongs in a row - straight pin, two on top two on bottom - square pin
On a bulb note I recommend trying the panasonic PC bulbs the 10K is very bright and the actinic is a great purple/blue. Check with ocean Aquatics great price and shipping is very reasonable
BTW - Good to meet you last night at Jim's.
