LED Tube Light (SA218, 1200mm, 5year Warranty Time)

Additional Info.

Product Description

When calculating the average brightness per inclination angle and turn it off in a graph, the beam angle can be computed, being 133 degrees for the C0-C180 plane and 108 degrees for the C90-C270 plane. 

Luminous flux 
With the averaged luminance data at 1 m distance, taken from the graph showing the average brightness, the luminous flux calculation. The result of this computation for this led tube is 978 lm.

Efficiency 
The luminous flux of 978 lm, 10 W,forsted so luminous efficacy is 98 lm / Watt. 

Electrical characteristics 
The power factor is 0.96. With this power factor means that for every 1 kWh net power consumed, a 0.27 kVAhr for reactive power. 

Voltage V 230ACV 
Supply current 0.055 A, 
Power P 10.2 W, 
Apparent power: 12.7 VA. 
Voltage and current waveform recorded for this led tube . if you want to know how the voltage and current waveform is measured please check the OliNo site 
Form voltage across the LED tube and current through the led tube 
This stream is checked on requirements posed by the norm IEC 61000-3-2:2006 with Amendment 2:2009 which contains requirements for lighting equipment <= 25 W and> 25 W. For more information about the IEC 61000-3-2:2006 request from OniNo 
The harmonics of the current plotted against the requirements for harmonics from IEC61000-3-2: 2006 and A2: 2009 

For lighting equipment <= 25 W there are no limits for the harmonics. 
The Total Harmonic Distortion of the current is computed as 20%. 


led tube Temperature measurements 

Temperature image (s). 
Led tube itself has a low emissivity. In order to measure its temperature using masking tape. A low emissivity means that the material is poorly kwijtkan heat by radiation. 

Led tube status: > 2 hours on 

Ambient temperature :24 ° C 

Reflected apparent temperature 24 degrees C 

Camera :Flir T335 

Emissivity: 0.95 (tape) tube is much lower. 

Measurement distance :1.5 m 

IFOV geometric :0.136 mm per 0.1 m distance 

NETD (thermal sensitivity) :50 mK 



Color temperature and LED tube power spectrum 

The color spectrum of the light from this led tube. Energy valid at 1 m distance. 
The measured color temperature is 4315 K which is neutral white 

The temperature is measured straight underneath the led tube. The color temperature can also be measured at different tilt angles. 

The color temperature of the led tube depends on the tilt angle. 

The color temperature is given for inclination angles up to 80 degrees. Beyond the luminance is too low (<5 lux) that it has not been used for color determination of the light. 
For the C0-C180 plane: the beam angle of 133 deg is equivalent to 66.7 deg inclination angle, this is the area where most of the lighting is. The maximum variation in correlated color temperature in this area (tilt angle) is approximately 0%. 

For the C90-C270 plane: the beam angle of 108 deg is equivalent to 53.8 deg inclination angle, this is the area where most of the light is. The maximum variation in correlated color temperature in this area (tilt angle) is about 1%.
