The stand is 4 feet long with 3 shelves and four lights, with four bulbs in
each and have electronic ballasts.

This is unfortunate. Electronic ballasts are not recommended for damp, humid
situations, which is what you have in a light garden. It should be purchased by
someone who is planning to grow succulents.
Unless the situation has changed in the last few years.
