I wonder if I can use the following bulbs to light varios areas of my
home where I like to have a lot of light:

400 watt BT37 Mogul Base Coated Horizontal Burn +/- 15 degrees High
Output Position Oriented Metal Halide Sylvania Light Bulb
(Sylvania MS400/3K/HOR 64498)

You need the right fixture, and a Metal halide ballast, and cooling for
both.

Metal Halide bulbs are used quite often for horticulture, so check in
the indoor growing area. 175 and 250 watt would be more common, as they
throw a LOT of light, and a 400 watter would light up a warehouse.

For example, the local box store has the smaller bulbs on the shelf.
