Here is a photo of my island with the old chandelier and before cabinets were painted. The above lights will replace the lights in this photo.

As per houzz: Above an island. When thinking of pendant lighting what probably comes to mind first are fixtures hung in a kitchen. They are a great solution for providing adequate task lighting while also providing an opportunity to enhance or reinforce the kitchen design. Typically pendants should be placed 28 to 34 inches above the countertop, or 72 inches above the floor.

Your lowest (bottom of the light) should be 36 above the counter top , and the highest probably no more than 42 inches above the counter. My bet is your light is showing no more than that variation. And my second bet is it is already "fixed" to vary the height between the individual lights. The longest length on the fixture is 25.5 inches, and a check of the installation sheet shows you how they attach.

This means if your ceiling is nine feet, versus eight, the fixture is actually a bit short for your room unless the fixture allows for more adjustability . Check the spec sheet and install instructions
