A discharge lamp is provided with a tubular discharge vessel having an internal diameter of at most 5 mm, with a luminescent screen, and with a filling which comprises mercury and a rare gas. The rare gas comprises more than 98 mole % neon, and the luminescent screen comprises a first group and a second group of luminescent substances, which first group comprises luminescent substances for converting UV radiation generated by mercury into visible light, and which second group comprises luminescent substances for converting the UV radiation generated by neon into visible light. The discharge lamp has a comparatively high luminous flux immediately after ignition even in cold surroundings.
