Copper Vapor Lamp

Unearthly Green instead of Sickly Yellow

Sick of the sickly yellow industrial feel of your sodium vapor street or warehouse lamps? Switch now to the unearthly green-blue glow of our new copper vapor lamps. Same idea as a sodium vapor lamp, but (I imagine) a lot more engineering involved!

* Strontium vapor lamps also available for a more festive street atmosphere....

       Yes ... why is it that hospitals always seem to install lighting that makes patients look iller than they actually are ?
