The wire does not come in contact with the metal end cap or the insertion pins, instead it touches only the glass tubes. Sorry this wasn't clear. Using a bare wire can have the same hazards as any metal conductor would, such as metal reflector.

If you are really concerned about shorting the ground wire the use of a ground fault breaker or outlet will add additional safety and may be a reasonable precaution since the exposure unit is not a UL certified device.
