So recently i have just found a Philips SL Kubo Lamp which i will share the picture in a while, with a box containg 4 of them (original carton). I wonder has philips made any of these lamps back then and if they were mass produced?

This was indeed a mass production product. It was marketed as SL Kubo under the Philips brand name and as Fee Kubo under the Mazda brand. However, I don't think these were sold in large quantities. The plastic housing could be either black or white.

Here are some pictures:
