The Lowel DP kits are tungsten kits. You need, I think from your description, daylight lighting. One option: the Lowel Caselight with daylight bulbs:

Note that you can use the same daylight units to light your windowless studio.
Another alternative is to go with tungsten units and add 1/2 CTB to each. Remember when you see out the window you want the outside to be around 2 stops hotter than the inside.
Finally, for LED options, do a GoogleSearch. Two quick choices: BHPhotovideo.com, search for "LED", and CoolLights. (Their server is down right now.)
