... with T16 high-output The ambient temperature of alamp affects its lumen output. As comparative measurements using twin-lamp ZX T26 andTECTON T16 fitted with variouslamps have shown, each lamp responds differently to tempera-ture changes. The light outputratio of T16 (2/80 W or 2/49 W) and T26 lamps (2/58 W) variesby approximately the sameamount at temperatures above 25 C. The thermal economy and output ratio of the T16high-output version are better atlower temperatures. At all tem-peratures, theirlight outputexceeds that of comparativeproducts, and this means that fewer T16 2/80 W R or RCmodular luminaires need to beused compared with ZX 2/58 W R or RC luminaires in order toachieve the same illuminance.

2/80 W TECTON-I at 25 °C and 500 lux was adopted as basis for assessing the tempera- ture gradient. The “cool spot” corre-sponds to the marking printed by the lamp manufacturer or the lamp type designation. TECTON-I R TECTON-I RC ZXXR ZX XRC Flexible Spacing … TECTON has thefeature of allowing luminaires to be positioned anywhere along its length. This means that by spacing them cor-rectly to where your calculation de-signs and predicts, means you will require less luminaires overall, to purchase, install and maintain.

Arrangement of light sources In order to optimise light output, light sources in the TECTONcontinuous-row lighting systemmust be arranged so that cool spots coincide with cool spotsand hot spots coincide with hotspots. Otherwise, according to information provided by lampmanufacturers, luminous fluxesmay differ. This also applies to vertical arrangements of T16 lamps.
