Abstract
An electrodeless fluorescent reflector lamp has a discharge vessel containing a fill, a solenoid in a reentrant and indium on the inner wall of the vessel acting as a primary amalgam. A secondary amalgam of indium may be provided on the reentrant. The primary amalgam is preferably under an insulative skirt. The vessel has a light reflective coating on the inner wall under the skirt. The exhaust tube is tipped off at the proximal end of the reentrant or is omitted, the vessel being tipped off at the distal end of the reentrant.
