Take everything I just said with a grain of salt.That seems to be a southern phrase, I thought I used it just because it sounded better that I don't know.
Just to qualify, I only play with lighting and have no professional training.
The closest I've been able to get that sunshine look is to take a strong flood light back off about 4 feet and use a plasitc lens (like you see on flourescent lights) and diffuse the light and even then I got a little whiter light than I wanted.
If you use the cheap clamp on lights, which do work well, you might want to consider what type bulb, (that makes a difference). The cheap Walmart brands shine a little yellow for me.
Anyway, that's my SHINE on it.
