Lumatek 600 watt digital grow light

Hi, I have this Lumatek 600 watt digital ballast with a hps bulb and air cooled reflector. All used very little. Can plug in and check out. This has the 110 volt cord. Very quiet. $175.00 I also have a cheap 400 watt digital ballast with 2 bulbs for $75.00. Works great. Thanks, calls are best. Please, no texts.
