Abstract
The invention concerns a gas discharge lamp or vessel wherein at least part of the lamp is in the form of a spiral. The windings of the coils forming the spiral are tightly-spaced (less than 1 mm apart). In addition to providing high amounts of light, the compact packaging resulting from the design offers safety advantages in that the electrical contacts are located deep within the vessel interior. Thus, the opportunity of contacting live electrical contacts in the event of glass breakage is lessened.
