Here are the measurements made on my equipment using precision lab scales pre calibrated with a 200gm physics standard before measurements and calibration check for delta after measurements.
1 DJI Mini 2 with ND filter and battery inserted = 239 gm
2 Cree standalone strobons with downward facing plastic clips 3D printed = 10.93 gm.
Total with Crees attached = 249.93 gm.
… and that includes an ND filter on the gimbal.
Hopefully that will stop people worrying about whether the attachments push you over the < 250 gm threshold.
The delta shift before and after measurements was zero over three sample measurements.
