One of the few HPS bulbs with resistance! usually mercury lamps have a resistor because it is necessary, hortilux usually put a resistor in the HPS, strange lamp, is it of Polish origin?
However, 250w isn't much for an indoor space because it's 30,000 lumens, you weren't wearing sunglasses, even 70w is a lot for an indoor space, how strong is the light at 250w?
Yes, they are indeed very strong, the 600w is the highlight, they reach 90,000 lumens!! I prefer 70w because they are small bulbs and not so blinding light
@@johnjunior-70 I'm also more into 70W ones. They can easily be used as indoor lights. I have a project in my mind to make a high pressure sodium desk lamp.

250W HPS lamps are pretty strong inside. The light was passing trough my window and even lighting up the other side of my apartament building.
