This kit comes with:

600w Horti Gear Ballast (formally know as Pro Gear)

6 inch Air Cooled Reflector (small)

600w Dual Spectrum Bulb

The ballast included in this kit was featured in hydromag :

"If you’re after a high output ballast, with a decent build quality, then this is the one for you. One of the few ballasts to carry the ‘mark of quality’, you can rest assured the overclocked performance will be one of the safest you can buy. "

An excellent purchase!
