Led lamp arrangement with svm reduction circuit

An LED lamp arrangement for replacing a fluorescent lamp in a luminaire having an electronic ballast, the LED lamp arrangement comprising:

• a plurality of LEDs;
• an SVM reduction circuit comprising an energy storage device connected across the plurality of LEDs;
• and
• a measurement and control circuit adapted to measure the current drawn from the electronic ballast and generate an output to the SVM reduction circuit;
• wherein, based on said output, the measurement and control circuit is configured to deactivate the SVM reduction circuit when the current drawn from the electronic ballast does not exceed a threshold, and activate the SVM reduction circuit when the current drawn from the electronic ballast exceeds the threshold, such that:
• the LED lamp arrangement operates in a first operation mode in which the SVM reduction circuit is deactivated, when the ballast is a constant current ballast, and;
• the LED lamp arrangement operates in a second operation mode in which the SVM reduction circuit is activated, when the ballast is a constant power ballast.
