the grid voltage. Color temperature as a function of inclination angle. The measured color temperature is 2775 K which is warm white. Luminous efficacy The luminous flux being 252 lm, and the consumed power of the lamp being.0 Watt, results in a luminous efficacy of 64 lm/Watt. S/P ratio The S/P ratio and measurement is explained on the OliNo website. These averaged values are used (later) to compute the lumen output. S/P ratio.2 This factor indicates the amount of times more efficient the light of this light bulb is perceived under scotopic circumstances (low environmental light level). I2 x t after 10 ms at 0 deg voltage start angle.700E-5 A This is the I2 t value when a zero crossing detector is used to start the voltage from 0 degrees. C-planes since the lamp is symmetrical along its 1st axis.

Chromaticity diagram The chromaticity space and the position of the lamps color coordinates. Power.0 W, follow the link for more information on electrical properties. The lamp consumes.0 W and has a luminous flux of 252. The luminous flux measured is 252. The classification of this lamp needed to determine the useful flux is: Other directional lamps. In this area the Ev is linearly dependent from (1/distance)2. It is the surface of the reflector at the front. For lamps where there is already no energy content near 350 nm, the values 300-349 can also be set at zero then. These cost about 8 maria lundström cdon Canadian each. Luminous flux 252. 300-350 nm values stuffed with 0s yes In the event OliNo has measured with a SpB1211 spectrometer without UV option then the irradiance data of 300-349 nm is missing. R8) are averaged to compute the Ra which is equivalent to the CRI.
