I was afraid of that but was hoping you got more info or there was another component to the unit that was not shown. I dont know, maybe you can get the light afterwards, since for a dollar is not even worth griping that this guy represented this as a light unit not a power supply. Ah well, just send the guy his dollar and look into making an exposure uinit yourself. You can make one fairly cheap, read the article Sandy wrote about exposure lamps, some of the actinic mercury lamps come up on e bay from time to time.
