Using a nikon sb700 flash/led light with Westcott 7 Feet white/black umbrella? - 1

The sb700 obviously used for photography.
Anyway, I also own an LED light kit with 600 led bulbs. It seems pretty bright when lit up. I have ordered a Westcott 7 Feet umbrella with the white interior and black exterior.
My question then is, will any of these light sources be powerful enough to achieve an effective lighting with this umbrella considering it has the white interior?

Here are the links to the led light kit and umbrella I'm talking about:

Light kit - http://www.amazon.com/...t/B00ATTY…

Umbrella - http://www.amazon.com/...t/B004QEV…

-These will NOT be used at the same time.
For video I will use the led light and for photography I will use the flash.

- For photography it will be for portraiture or a small space, including a person.
- For video it will a similar situation.
Bottom line, it will not be used to light up an extremely large area, like a hallway, but more like part of a large room (video), or just a small staged area (photography).

I'm aware that this may be up to me to test the equipment, but if for some reason any of these are not powerful enough, please recommend me light sources that are great quality but affordable.

I believe both objects will be of great use, especially the Westcott 7 Foot umbrella. It will, however, project a soft and narrow beam of light onto its subject, but the 7' Silver Parabolic Umbrella will also offer maximum light reflection for use either indoors or outdoors. (As seen below)

As for the 600 LEDs, it offers a full spectrum, beautifully soft light. LED lights off significantly further "throw" than a comparable fluorescent light. This is because each of the 600 LED lights has a 30 degree beam angle lens that directs light forward.

So yeah, your 600 LED lights offer the brightest light in the smallest form factor.
