I suggest a white shade cloth instead of black.

My new lamps are metal halide. I have them fairly high above the plants,

but

I will take Kipp's advice and stretch a shade cloth between the light and

the

plants. Many of the plants are young seedlings and thus more sensitive to
burning.

I assume your new fixtures are a metal halide or high pressure

sodium.

These are indeed strong lights and can burn even full sun-loving plants. I
would suggest shading with cloth or placing more sensitive plants outside

the

"cone" of light directly beneath the fixtures.

Just to note: If you lights are still fluorescents then they are

unlikely to

burn anything unless the bulbs are within inches of the plants.
