Do not watch into the bulbs directly.

It's unfiltered UV light which can burn your Retina.

In an earlier comment I mentioned that "The amount of UV radiation emanating from the exposure unit wouldn't be enough to cause any noticeable damage." I was referring to normal everyday use shouldn't be an issue, but please do not stare directly at these bulbs as well. Thanks "normangbates" and "steve0one" for the reminders. You can never be too careful.

From personal experience, or did we leave out a step? :)

you are using UV light blubs right? for one looking at the blubs when it is on is not really good for your eyes.... and having the power off is always safer and of couse using a coth to ajust the blubs, using your fingers is not recommened, as the life time of the blubs will be cut short.

Per the manufacturer, the bulbs used in the system are standard bulbs one might find in a Walmart or hardware store. The amount of UV radiation emanating from the exposure unit wouldn't be enough to cause any noticeable damage. Although, it is NOT suggested to stare at any light source. About touching the bulbs with your fingers, the amount of heat given off would not be enough to crack the bulbs even with oil from fingers remaining. Also, it is only advised to rearrange the bulbs if needed.
