Not trying to rip off Philips at all there with the style of the packet

Packaging design does look to me as if they are copying Philips but at the same time not making it super obvious so that Philips doesn't flag copyright on this Chinese manufacturer/labelling brand. It reminds me of the copycat techniques that you see with Lidl and Aldi own supermarket range of their products a bit

Otherwise the colour quality of that lamp looks brilliant to me

I like how they print the Turnhout symbol on them, I wonder if the Chinese even knows what that is?, pretty good though you can still buy new halides on Ali Express Cool

This lamp takes very long time to stabilize.

@Flurofan96: I think that the quality of the light and CRI are much lower than lamps with Dy-Tl-Cs like the Sylvania HSI-TD 70W/D.
