need info my fellow grow friends

im looking at buying another grow light 400 watt hps and was wondering if they are all swicthable like the one i already have (hps/mh ballist) any input would be greatly appricated.

i dont think they all are it depends on if it has a swicthable (hps/mh ballist).

The product description of the light will tell you if it's switchable. If there is no mention of switching ability then assume it is not.

Whether its switchable or not, One can just purchase MH conversion Bulbs.

IMO Switchable is bullshit.
