Exceptional reliability

These lamps combine high efficiency and long life with an improvement in colour appearance and rendering compared with low pressure lamps. SON lamps emit a golden-white light. The SON-T lamp, with its clear tubular outer envelope, lends itself to applications that demand precise optical control, e.g. floodlighting. The SON-E lamp, with its elliptical glass bulb, inside which a white diffusing coating is applied, suits other applications where such accuracy of light control is not so essential. An ignitor (internal or external) is used to supply the high voltage necessary for lamp strike up. Reliable strike up (when hot, less than 60 seconds) thus is ensured, and a simple choke is used to stop excessive voltage rise. The run-up time can be up to 6 minutes when cold.
