I have purchased items twice from these guys and they are great to deal with. They are very knowledgable and all my questions are answered FAST!

This time around I purchased some BLITZ Dual Tube Halogen bulbs in 6000K and the shipping was pretty fast and the item was packaged nicely. I will definately shop with them again and again!

By the way... these are the lights:
