LED lights give off strong UV rays which can be harmful to the eyes.  Not sure if it is an issue at 13W, but at 80W they can certainly damage ones eyes and without an enclosure, a lot of the light is being lost - a reflective wall system would be much more efficient.

 

May be you are talking about mercury vapor lights. If the outer glass is broken, the bulb inside will send out harmful UV rays.

LED chips can only generate one single frequency (color) of light. Actually there are no white LEDs. White is generated by using phosphors or using three color LEDs in combination.
