3 Photometric data Spectral power distribution Wattage CCT [K] Properties DIN 35 Class Lucalox TM XO Clear Tubular Figure Lucalox TM XO Diffuse Elliptical Figure Relative intesity Wavelength [nm] Survival rate and lumen maintenance Average lamp life & lumen maintenance is based on laboratory tests of a large number of representative lamps under controlled conditions, including operation at 11 hours per start on ballasts having specified electrical characteristics. The following conditions can reduce average lamp life and lumen maintenance: frequent on/off switching high line voltage excessive vibration high ambient temperature within the fixture ballast and ignitor characteristics. Survival rate of XO W lamp 3 1-2W Survival rate of XO -W lamps 3 W 1 W Survival rate of XO W lamp 3 1 W Survival rate of XO 1-W lamps W Average rated life The survival of individual lamps or particular groups of lamps depends on the above described system conditions (see Lamp Survival graph). For cost-of-light calculations involving these lamps, the following estimated operating time is suggested: % survival at 35, hours for W,, hours for W-W, 45, hours for 1-W and 32, hours for W.

4 Lumen maintenance Under the same controlled conditions, Initial Reference lumens refer to the lamp lumen output after -hours burning. Due to variations in systems and service conditions (in particular the burning cycle), actual lamp performance can vary from the reference lumen ratings. The lumen maintenance (light output during life) of individual lamps or particular groups of lamps can be seen on the Lumen Maintenance chart. Lumen maintenance of XO -W Lumen maintenance of XO -1W %of rated lumen %of rated lumen W W -1W Lumen maintenance of XO 2-W lamps Lumen maintenance of XO W % of rated lumen Electrical data Data is based on a nominal lamp operating from a nominal choke (reactor) ballast with power factor correction. Supply power is based on a typical commercially available ballast. Run-up characteristics The graph shows typical run-up characteristics for a 1W Lucalox TM XO lamp. The time needed for the light output to reach % of the final value is determined by the supply voltage and ballast design. Typical values are: W W Watts 1 2 Run-UP (Mins) % of rated lumen Wattage Volts ±15 [V] Current [A] Power [W] Current Crest Factor Lucalox TM XO Clear Tubular Lucalox TM XO Diffuse Elliptical Percentage of final value (%) Typical run-up characteristics Time from switch-on (sec) P lamp V lamp I lamp lm

5 Hot restrike time All ratings restrike within 4 minutes. This occurs when the lamp has cooled to a temperature at which the starting aid can re-establish the arc. The new solid state starting aid is integrally bonded to the arc tube for shorter restrike time, and improved reliability no moving parts or welds. Supply voltage Lamps are suitable for supplies in the range 2V to 2V /Hz for appropriately rated series choke (reactor) ballasts. Supplies outside this range require a transformer (conventional, high reactance or CWA) to ensure correct lamp operation. Lamps start and operate at 1% below the rated supply voltage when the correct control gear is used. In order to maximise lamp survival, lumen maintenance and colour uniformity, the supply voltage and ballast design voltage should be within ±3%. Supply variations of ±5% are permissible for short periods only. This may be achieved by measuring mean supply voltage at the installation and selecting ballasts with appropriate settings. Relative change (%) Effect of supply voltage variations on performance Lamp Voltage % Supply Current % Lamp Wattage % Light Output % Relative supply voltage (%) Ballasts It is essential to use a ballast appropriate to the supply voltage at the luminaire. Typical wiring diagrams for control circuits incorporating Superimposed or Impulser ignitor and choke (reactor) ballast are shown.

6 Ballasts To achieve correct lamp starting, performance and life, it is important that the lamp and ballast are compatible and suitably rated for the supply voltage at the luminaire. The Lucalox TM XO range is compatible with IEC662 (High Pressure Sodium Lamps) and IEC635 (HID Lamp Safety). Ballasts used to operate these lamps should comply with ballast standards IEC922 & IEC923 and incorporate adequate overload protective measures to ensure that safety is maintained under abnormal lamp end-of-life rectification conditions as prescribed by IEC662, IEC635 and draft changes to luminaire standard EN Ballast thermal protection is one method of providing adequate protection. Ballast voltage adjustment Series choke (reactor) ballasts incorporating additional tappings at ±1V of the rated supply voltage are recommended. Alternatively, a single additional tapping 1V above the rated supply voltage will ensure lamps are not overloaded due to excessive supply voltage. Ignitors Ignitors should comply with specifications IEC926 and IEC927 and have starting pulse characteristics as shown in the table on the right. Timed ignitors Use of a timed or cut-out ignitor is not a specific requirement, but it is a good optional safety feature for the installation. The timed period must be adequate to allow lamps to cool and restart when the supply is interrupted briefly (see Hot Restrike Time ). A period of 1 minutes continuous or intermittent operation is recommended before the ignitor is automatically switched off. Commercially available 1/11 minute timed ignitors are suitable. Cable between ignitor and lamp Cables connected between the lamp and a superimposed ignitor Lp terminal, or the ballast when using an impulser ignitor, must be rated at a minimum /Hz voltage of V. Mineral-insulated cables are not suitable for connecting the lamp to the control gear. To achieve good starting superimposed ignitors must be adjacent to the luminaire. Cable capacitance of wiring between the ignitor Lp terminal and the lamp should not exceed pf (<1 metre length) when measured to adjacent earthed metal and/or other cables, unless otherwise stated by the ignitor manufacturer. When using impulser type ignitors, longer cable lengths between ballast and lamp are normally permissible. Limits for particular ignitors are available directly from the ignitor manufacturer. PFC capacitors for choke (reactor) circuits Power Factor Correction is advisable in order to minimise supply current and electricity costs. For 2-2V supplies, 2V±1% rated capacitors are recommended as follows: Watts 1 2 PFC Capacitor (µf) Watts Min. Pulse Voltage [kv] 1 Max. Pulse Voltage [kv] 2 Min. Pulse Width [µs] 3 Min. Pulse Repetition Rate /½ cycle /½ cycle /cycle /cycle /cycle /cycle /cycle 1. When Loaded with pf min. 3. At % peak voltage 2. When Loaded with pf max. 4.
