LSRF-3 is equipped with Class A fast photometric probe, so the sampling speed is up to 100kHz. It fully meets the requirement of BASIC, Energy Star V2.1, IEC TR 61547-1:2020 IEC-Pst, CA CEC, ASSIST, CIE TN006-2016 CIE SVM, IEEE Std 1789 standards, etc. It is professional for flicker test of LED lights and lamps, energy-saving lamps, etc. According to EU directives 1194/2012, 2009/125 / EC, SASO2902, EU2019/2015 - EU2019/2020 and IEC60969 "Self-ballasted Lamps for General Lighting Services—Performance Requirements" and other requirements.
2. Lamp Start and Run-up Test: the LSRF-3 needs to work with LISUN's LSP-500VARC AC Power Source (With Trigger Function) or LSP-500VARC-Pst (IEC-Pst AC Power Source) to test the Start and Run-up time of lamps which is according to clause 11.4 Start Time Test Method & clause 11.5 Run-Up Time Test Method in the US Standards of Energy Star V2.1, and SASO2902 Table 13:
