Yes it's true. I was picking up some stuff to build my latest aero unit and found some T5 fixtures and bulbs in the lighting section and the best part of it was they are half the price of what I've found online for the same thing. They don't come with reflectors though. I paid about $39 for the 46" fixture (2 bulb) and about $11 for two bulbs. I've never seen a T5 before; they are skinny little dudes. The bulbs are 3500 Kelvin.
