First one is HPS(high pressure sodium) second is MH(metal halide)

MH are best for veg, HPS are best for flowering.

MH is usually 5100 kelvin in color temperature
HPS is usually 2100k

HSP for flowering. The HPS bulb looks like the rolling pin granny used to roll out the FLOUR
when she made pies. Get it?

Anyway I can help, BigSteve.

The important question is.......
Do you have the relevant ballasts for them.

HPS always have those cylindrical translucent ceramic inner capsules. MH have the transparent blown quartz capsules. cn
