I just got this off of the plant list. 150 watt HQI ballast & fixture (ballast is core & cap) for $150 US ($135 if 4 or more are purchased)

On the website it says bulb not included but someone on the plant list phoned and said the bulb was included (10K bulb).
Not a bad deal if your looking for that wattage
ps. I have no affiliation with this company
