Below a graph showing the color temperature for different inclination angles.Ĭolor temperature as a function of inclination angle. This color temperature is measured straight underneath the light bulb. The measured color temperature is 2792 K which is warm white. The spectral power distribution of this light bulb, energies on y-axis valid at 1 m distance. Warm up effect: During the warmup time the illuminance doesn’t vary significantly ( 2 hours onĬolor temperature and Spectral power distribution The ambient temperature during the whole set of illuminance measurements was 23.6 – 25.1 deg C.The temperature of the lamp gets maximally about 7.5 degrees hotter than ambient temperature. It is the surface of the opening and also the wall that is lit. This factor indicates the amount of times more efficient the light of this light bulb is perceived under scotopic circumstances (low environmental light level).ĭimensions of the luminous area (used in Eulumdat file). The total number of photons in the light of this lamp. It indicates a kind of efficacy in generating photons. The total emitted number of photons by this light, divided by its consumption in W. Value valid at 1 m distance from light bulb. The number of photons seen by an average plant when it is lit by the light of this light bulb. TM30-15 is an improved indicator (over CRI) of how well colors are rendered. This label is an update of the previous version, and compulsory from Sept 2013. The energy class, from A++ (more efficient) to E (least efficient). Measured with photogoniometer, calculation done as described in LM79-08. This current has been found at a voltage start angle of 90 degrees. Is a measure for the amount of flickering.ħ7 deg is the beam angle for the C0-C180-plane (perpendicular to the length direction of the lamp) and 115 deg is the beam angle for the C90-C270 plane, which is along the length direction of the lamp.Īn electrical load with this power factor means that for every 1 kWh net energy consumed, there has been 1.57 kVAhr for reactive energy. Measured with a light sensor looking at the lamp (angle not defined). See this overview for a comparison with other light bulbs. Many parameters are also found in the Eulumdat file. This article shows the measurement results. The lamp consumes 0.9 W and has a luminous flux of 52 lm. The measurements from OliNo show that the lamp emits a warm white light with a color temperature of 2792 K.
