What is a KSA-3 bulb????

Lightfoot98 · Oct 13, 2011

Found this in an old reflector assembly. Don't know what
kind of flashlight it was from. Looks like a regular reflector from
any standard flashlight. Metal with a screw in plastic sleeve
plug to hold bulb.

Bulb is a PR style base with straight sided globe with lens at tip.
Globe diameter is slightly smaller than the base diameter.
Globe length looks same length as base.

Marked "KSA-3 USA" stamped into base.

Found 3 adjustment washers between bulb and reflector.

Any Idea as to what this is????

Made for Mag-Lites.

Actually manufactured by Carley, before production shifted to Mexico.

The " 3 " indicates it's for 3-cell flashlights.

KS denotes Krypton Star

They would often include several of those thin round shims in each package,
so that you could "adjust the focus" of this lens-end bulb, when using it in something besides
the Mag-Lite. Not needed, of course, in any "adjustable focus" flashlight.

Hope this helps.

Thanks Burgess.

Are they still being sold?

Probably the standard Mag "White Star" bulb, so I'd say yes. The MagnumStar is an improved version, though.
