Metal halide lamp for irradiation of plants. Notable for the shape of the flask. To power this lamp, you need a 380V supply and an appropriate ballast. I managed to run it at 1/3 of the power from LATR regulated transformer through a choke for DRL 1000 and IZU. To start, I also had to additionally touch a lamp with a plasma ball. It is not very correct to judge the color of the glow in this mode, but it is very pleasing to the eye and is well reproduced in the photo No. 3.
