What is the maximum wattage and is it small base or medium based?
The sockets are medium based & max 120 volt. I use 4 Eiko 30 watt, 120 volt, 5500 kelvin bulbs that I purchased from Adorama. I absolutely love it! I shoot alot of newborns & young kids & love natural light, but when it is not available I use the florescent 4 bulb adapter in the uLite. I do this so I don't run any risk of burning or overheating the newborn. It has worked great for me.
