Help me choose LED in South Africa

Hey guys,

Im located down in South Africa and our selection of goods to buy is quite limited to a few stores.

Is anyone perhaps willing to helping me choose the best LED light from these few stores i have access to?

I have a 1.5m x 1.5m x 2m / 5" x 5" x 6.5" grow tent and want the best possible yields. Capital isnt a problem.

We would like to grow as much as we possibly can in this space.

I Cant find these specific lights anywhere on the web: The Nova and Saga
Nova LED S8 360w - No info on true watt

SAGA LED 430W - No info on true watt

These 2 lights are no brand: The 600w and 1000w

Cob light, only heard good things about it: Is it worth?

One last question, whats your preferable amount of plants to grow in this size tent?
