I purchased this unit with a working lamp. Only to have it break on me when I cleaned it. Knowing full well that replacement lamps do not exist. I tracked down some parts (see pictures) GX10Q 4pin base, two self tapping screws and a new black light lamp. I removed the old lamp base clips without cutting the wires. Installed the wires and screwed the new base to the unit. Reassembled the cage, plugged it in and IT WORKS! Now I can't wait for warm weather and bugs.
