Light measurement made easy First portable complete measurement solution

Light measurement made easy What’s inside Universal power input Light source power USB to computer

Lumen Peak candela Color temperature CRI Beam angle Angular field distribution Power Power factor Lumen per watt In 30 seconds Light measurement made easy

Full automatic just click Automatic integration time set Automatic adjustment for ambient light Automatic goniometer speed set Automatic beam centering Light measurement made easy

High resolution up to step per 360 degrees High accuracy goniometer Low: 50 intensity points Medium: 100 intensity points High: 300 intensity points 3 selectable resolutions

Automatic quality control for optimum resolution High accuracy goniometer System automatically rescan beam section if resolution is to low due to a narrow beam.

Lumen value calculated using patented spherical method Lumen measurement The non-circular part of the light distribution is measured and then used to calculate the complete integrated luminous flux. ==

Circular B field error How accurate is lumen measurement using viso technology ? Lumen accuracy Spectrometer error + sensor error + circular field error = Total error = = = = =

spectrometer intensity error + sensor error + (circular field error type1+ type2+ type3+ type4+ type5) / 5 = total average lumen error = 0,5% + 2% + (1,6%+2,3%+4,6%+7,9%+10,2%) / 5 = Lumen accuracy Average accuracy Total average lumen accuracy +/- 7,82%

The LightSpion is first measurement system to fully support limited cone measurement. Spherical limitation New EU regulation No 1194/2012 requires from September 2013 directional lamps to be specified in lumen limited to a cone of 90° or 120 ° — directional lamps with a beam angle ≥ 90° other than filament lamps and carrying a warning on their packaging in accordance with point 3.1.2(j) of this Annex: rated luminous flux in a 120° cone (Φ 120° ) — other directional lamps: rated luminous flux in a 90° cone (Φ 90° ). Text from EU regulation Example: Lumen is only calculated in a 90° cone (white part) grey part is considered waste light in new EU regulation. Total: 258 lm 90° cone: 201 lm Waste light: 57 lm
