These are the lights I am using they use a passive cooling system, no fans. They are white lights, actually a blend of cool, warm and infrared lights, but white to the eye. They grow compact plants with great colour. I keep one foot between each light and the plants between the lights still show great colour. Its a great spot for plants needing a little less light. I'm able to grow plants that want indirect light up to 6" away from the lights without issues.
The window behind the lights are west facing windows. On normal summers the window shades are shut all summer long to keep the house cooler, but open the rest of the year. This summer we have had very cool weather, so they have remained open. Even without the lights its too hot upstairs unless I close them during warm days. Very few people have AC in the PNW.

This red aloe is not directly under the lights, but between two lights and still has great colour. The picture does not show how bright red it is actually.
