long-arc lamp

[6.5.9.2]

An arc lamp in which the distance between the electrodes is large, usually greater than 10 mm.

Note: This type of lamp (e.g., xenon) generally has an arc tube containing gas at high pressure. The arc fills the discharge tube and is therefore wall-stabilized.

NOTE: This definition was changed in RP-16-17 Addendum 4.
