Novatron lights that I really like. The kit came with two flash heads, stands, umbrellas, cords etc in a hard carrying case. Also have a third novatron light with stand that was thrown in by the store. I like the way the bulbs are protected with glass since I have used White Lightnings and seen stuff fall and burst their bulbs (at about $80.00 a bulb makes a big difference.) Its a great portable starter kit and ran about $900.00 new. I know there are brands considered "better" but I have been really happy with these. Edited to add link to Novatron

I used them on this set of pictures

They can be triggered by your flash or a strobe light. In reading they seem to use them a lot for interior shots. They are small, hide well and can be placed in dark corners or behind thing that would block lights. Example here
