Halogen J Type Light
J Type halogen light bulbs
are double ended halogen light bulbs. The most common base type for J type halogen
light bulbs is called a "recessed single contact" (often abbreviated
RSC). The bulb shape is referred to as "T3" for "tubular"
(T) and 3/8" diameter. J type halogen light bulbs are also available in
"Pin Blade" base (PB). Pin Blade J types have a flat piece of metal
at each end used to make contact with the socket (this type of halogen light
bulb is becoming increasingly uncommon). J type halogen light bulbs are available
in various voltages, from 12 volt to 277 volt, and in lengths from 78mm (3.12")
to 254mm (254mm). J type halogen light bulbs are most commonly used in security
lighting and in high-end accent fixtures.
Please note that J type
halogen light bulbs should not be touched with bare skin. Halogen light bulbs
utilize a semi-permeable glass with can be penetrated by oil from skin. The
oil creates hot spots on the glass that reduces the bulb's life.
